Can’t trust my P365...too many failures.

Reading the op I see that first time he had 20 failures in 250(ish) rounds.

Second time he took it out he had 4 failures, out of 300 rounds of ammo.

I can fully agree with not carrying it at this point but declaring it a lemon is a bit early, I think. Some guns just take longer to break in than others.

Since the gun has gone back to SIG and come back with a clean bill of health, go shoot it some more, and see if you have 4 failures in 300 rnds now. Or less.

Sure maybe WWB isn't a good fit in that individual gun. Cheap ammo is cheap for a reason.

As to shooting FMJ, why not? Generally speaking I would run fmj until I was sure it was running perfectly, before running expensive self defense ammo.

if a gun chokes on ball ammo why waste expensive stuff until it no longer chokes on ball ammo?

Failure to fully feed and return to battery is failure to feed. FTF can be read as Failure to Fire, which is of course a different problem.

Cheap ammo is often the source of problems, and it is the easiest thing to change but its not always automatically the source of all problems.

Everything has +/- tolerances and sometimes they just stack up together and give issues.

Please do let us know how the gun runs the next time you get a chance.
 
I guess that he just assumes that he only needed to shoot FMJ Range Ammo for an evaluation..

I guess there are EDC guns that are finicky with some ammo but...
'most' make sure their gun works, with 'range ammo'(cheaper) and their defensive ammo..and new mags, and with any changes made with their EDC gun..I donno, it's the first thing I do..just got a new 15r magazine for my G26..went out yesterday to see if it worked Ok with various cheap and expensive ammo..FMJ, JHP, G9, Lehigh Xtreme Defense...

all worked 100%, BTW..

BUT, I think any modern EDC gun in 'modern' price ranges..they shouldn't be finicky with any kind of ammo..IMHO..
 
First off I am not a FANBOY!
I would be the first to state that there are NO GUNS that are Perfect..and Lord knows the P365 has had it's colorful past!
And there is No one Gun or Gun make for everyone.
If there was there would be a lot less guns in the world.

Nor would I make excuses for any reason that someone has a issue with a Sig.
However I was not born yesterday and I have posted about the P365 every day since it came out at SigTalk.
You can say that I've read it all..

It is rare that someone has a issue such as MontyCop05 has had.
There are more people that will Post that they never had a issue with WWB or any ammo than those that did..
but the WWB Exclusive issue Posts do exist and the end result is not that the gun always has to go back to Sig..
Most times it eases up with range time as the Gun eases up.
If not call Sig!

There are Enough posts about WWB that I would not purchase WWB and run it through my Sig's.
Why do I need to take the chance?
There are SOOOO Many choices for 9mm Ammo these days!
However if someone wants to make the stand that dagnabit it should eat everything thrown at it...then God Bless!

The rule of thumb is that if you can work it out.. Great... if not Call Sig.
Sig's are tight guns when new..know that and be aware of it.
Rack the Slides when new and feed it some good ammo while the cycle is easing up and after that run whatever you want through it.

That is what I did and 4,000+ rounds downrange I have been extremely Happy!
Then there is the shooter..is there anything that the shooter is doing that could be contributing to the issue? i.e Grip..Limp Wristing

Sig obviously found no issue with MontyCop05's P365 and Sig is very thorough.
For Battery Issues most times Sig Replaces the Recoil Spring..
It must say something that Sig found no issues.

Anyway I just try and pass on what I have read has worked for others..no excuses.
Sometimes our helpful suggestions help and sometimes they don't and back to Sig it goes.

If MontyCop05's Defensive Ammo also gave him issues along with issues across so may different kinds of FMJ Ammo and Sig found no issues..
What does that leave?
You post as much as I do..you have read a lot..What do you think..TunnelRat
What is your professional opinion?
Gun?
Ammo?
Shooter?
Something else?
Combination of..
So what if he doesn't ever fire a premium defensive round in it... Ever. It might be a compact SD gun, but who fires nothing but their SD ammo? So if his SD ammo worked, he should just stick to firing the SD ammo and be perfectly fine with it? A thousand rounds of SD ammo costs more than the gun.

Just getting the thing to work with common plinking ammo seems to be an issue... that is a pretty big issue all by itself.
 
Hi MontyCop,

Have you had an armorer take a look at it?

If it's an off-duty gun and not reliable, I'm sure you've already decided to sell it.

I used to carry a Model 60 that I bought when I go into LE. I've never trusted it to save my life. I've retired it. When I do carry, which is more rare than raw beef, I go with my flawless SA EMP 3 9MM. I have complete faith in it.

See Post_53. The OP had SIG examine the gun (presumably an Armorer) and test-fired 90 rounds with no problems. We'll just have to await the OP to test his gun again and get back to us.
 
Personally do not see what the big deal is on the 365. If you want to spend $500.00 on a new gun simply because it has a few more rounds then do it. If not, there are plenty of proven Micro 9mm's out there as well as revolvers. And if you really fell that you have to have more than the standard rounds, then just get a sub compact or compact pistol with a double stack magazine, No big deal. Heck, if I felt like I have to have more rounds, which I do not, I will just start to carry one of my Semi's with a 17 rd. mag.
I would say to also stay away from Hollywood movies.

It is a micro-compact with full sized duty weapon capability.

I got the gun back from Sig. Gunsmith found no defects, ultrasonically cleaned it and fired 90 rounds of fed and aguila 115g ammo with no malfunctions. I haven’t gotten a chance to test it again since getting it back. I have a bunch of different ammo to test when I do find the time, but as of right now, No, I’m not carrying it. I won’t until I put at least 500 more trouble free rounds through it. By then it will have over 1k through it. If I get any more malfunctions I will elevate the complaint with Sig and it will go back. Maybe permanently.

Could you be limp wristing the weapon or inducing a malfunction with your grip?

Lol man that sounds great for marketing hype. But like I said, just get a Good Double stack subcompact, or just a good solid single stack, or revolver. But I guess a 32oz Big Gulp is a whole lot better than a 12oz class of water to some folks. More will always be better to them.

Very well said. Could not agree more. The idea that a gun should shoot every ammo available to include cheap range ammo is just not real. Especially a nice gun with tight tolerences. They make them with tight Tolerences for a reason.

One box of Cheap range ammo that one of my guns would not shoot. Not sure I want a gun that will.
And I will say that any small Barrel gun can be limp wrested. Seen it happen many times and the owner declare a malfunction by the gun, Send it back and they find nothing wrong with the gun. Same thing occurs with the owner yet again. Then I have shot the same gun and all failures were non -existent.

In dozens of production pistols owned I have yet to have one that would repeatedly malfunction with WWB. These aren't hand fitted match pistols. While I agree that my own P365 is tighter than some of my other pistols, production ammo from an American manufacturer should work. Moreso, and for the idk how many time now, it also had issues with SIG ammo. Ammo literally made by the manufacturer. My own P365 had no issues straight out of the box, even when fired by my petite wife whose grip is certainly less than ideal.

Maybe it is the shooter. Maybe not. If only there was some way for the OP to check function and then report back to us...

And yet I have a batch of WWB that will malfunction in over a half dozen semi-auto's tested. Good solid guns. I will NOT buy any WWB. Over the years and seen too many failures. They seem to run in batches of good and bad. Just not worth buying.

Regardless, not worth the debate, you like WWB then there is plenty around. Each to his own.
 
It's not a matter of liking. I generally use other brands, by a wide margin. That doesn't change that in my experience it works in the pistols I've owned. And again, it wasn't the only ammo brand having issues in the OP's pistol.

When Wally’s announced that they were discontinuing ammo sales, I overreacted and bought up more WWB than I probably should have, so I plan on using it up.

Where I live I don’t have a lot of options for buying ammo so I guess I’ll be paying significantly more for what’s available from very limited sources.
 
I've used WWB for years and, though it might not be my first choice for self-defense duties, the stuff works fine in all of my many and different handguns. I don't dispute the experiences of others but I do think that WWB is not nearly as bad (again, not bad at all imo) as some on the internet allege. If it was truly as bad as some folks report, it would never survive in the market place.
 
Thought I'd add to dglud's post: I've used WWB for years in a number of calibers and have had no problems with it. In .45 ACP, it's as accurate as some of my best hand loads in fact. In 9mm, it's as good as Federal American Eagle 115 gr FMJ.

Additionally, in my P365 with a 2/19 build date, I'm over 1200 rounds now, of 115 & 124 gr mixed reloads & commercial loads, about equally divided between JHPs and FMJ's, and with a significant number (approx. > 300 rounds) of cast LSWC's. It's been a great pistol for my CC needs and fills that role daily. YMMv. Rod
 
Happy Thanksgiving Monty and L-2,

When I was in business of catching bad guys, I've carried on-duty at least four handguns manufactured by S&W, Sig, and H&K. My absolute favorite was my Sig P229 .40 S&W. I had and still have complete confidence in it. I have no clue of how many thousands of rounds I've fired through it with 100% reliability. The H&K USP .45 ACP and S&W 5904 were superb and flawless weapons. But my Sig P229 was my favorite. I had complete confidence in it. All three were/are more reliable than any revolver I've carried and owned/own.

At one time, possibly though the early 21st century, Sig was the definitive name in double-action semiautomatic law enforcement handguns. Of late, I've become aware of diminished quality control at Sig.

I have not read every post in this thread. I rarely read all posts in threads before offering an opinion. Who has that much time?

Having a Sig armorer examine Monty's gun is an option. However, were I Monty, I'd go with a POST certified armorer every time.

Every single problem I've had with a handgun (all were revolvers) save one I had repaired by POST certified armorers, all of whom were retired cops who had/have taken retirement gigs with my former agency. The lone exception was a Springfield Armory EMP 3. I knew it would probably have uncorrected problems before I bought it. If Springfield Armory had corrected design flaws common to the original version of the EMP 3l, CA DOJ would have considered it a new handgun. As a new handgun, it would have had to have been equipped with microstamping, a nonexistent technology. Hence, CA DOJ would not have allowed and will not allow a flawless version of the SA EMP 3 to have been sold/to be sold within CA. I was elated that Springfield Armory kept the EMP 3's original design for sale only in CA, flaws and all, because it allowed me to buy a copy. Springfield Armory's customer service is exemplary. I shipped my EMP 3 to Springfield Armory at its expense. Within two weeks, Springfield Armory's Custom Shop returned a flawless EMP 3 to me. It is a Custom Shop EMP 3. It has been 100% flawless thanks to Springfield Armory's Customer Service and artisans at Springfield Armory's Custom Shop. Every other Springfield Armory handgun I own has been flawless. I can't write that about S&W revolvers. I've had two that have suffered catastrophic failures and were repaired by my former agency's armorers.

My advice to cops is always go to their agency's POST certified armorers. Most armorers are retired cops. They know of the extreme importance of firearm reliability. They are ethically committed to officer survival. If a cop were to bring a junk gun to an agency's POST certified armorer, such an armorer would tell the cop to trash a junk gun that might used to save his life. POST armorers are not bound by manufacturer loyalty. They're bound by professional and ethical commitment to officer survival.

I'm honorably retired. I hold retirement credentials from my former agency. Hence, I'm viewed as an employee when it comes to retirement-carry handguns After I received my Springfield Armory custom Shop EMP 3, I asked one of my former agency's armorers to examine it for reliability. He is a retired cop. He disassembled it. examined every part of it, reassembled it, and told me that it was a perfect gun. I took it to my former agency's range and put about 150-200 rounds through it, range and duty ammo, without a single issue.

That's why I recommended a POST certified armorer examine Monty's gun.

I've read about too many defective guns that were returned to their factories and then returned to their owners with problems uncorrected along with manufacturers' claims that their guns met or exceeded manufacturers' standards, which were obviously inferior to PSOT armorer standards.

BTW, my former agency's armorers would not and will not approve for duty and off-duty use any handgun that did not/does not meet or exceed their agency's standards of reliability. POST armorers are only concerned with officer survival, not brand loyalty.

BTW, there were two armorers on duty at the time I brought my Custom Shop EMP 3 in for reliability inspection. Both agreed that the Springfield Armory TRP .45 was among the best (the best) on-duty law enforcement handguns. They said that simplicity of 1911-A1 design combined with Springfield Armory's unrivaled quality control created a perfect handgun. Based up their professional opinion, I bought a Springfield Armory TRP .45 ACP. They were 100% right. That gun is flawless. It has become my primary carry handgun when I'm fishing the Eastern Sierra and Rockies. The Springfield Armory TRP is the factory production version of its famed Custom Shop FBI gun. Springfield Armory's FBI gun bested all entries, including Wilson Combat, in that agency's vigorous firearms test. It was selected as the official handgun for specialized FBI units and many LE SWAT teams. In essence, one could pay twice as much for another brand, but he would not be buying a better gun than Springfield Armory's FBI gun. In fact, he might be paying twice as much for an inferior gun.

Monty, the above is a lengthy explication of diplomatically opining that it might be wise to sell your problem Sig and replace it with an EMP 3. Especially off-duty, without body armorer and no back-up, a completely reliable handgun is absolutely essential. I've long ago retired what was once the quintessential off-duty cop gun, an S&W Model 60, after reluctantly accepting the fact that it was a poor choice for saving my life. I'd sell it, but its sentimental value prevents me from parting with it.

BTW, Monty, besides its complete reliability, my EMP 3 is phenomenally accurate.

Monty, my primary concern is that you always return home to your family.


Stay safe my brother,

SATRP
