I have a friend who is thinking about getting a handgun in a .357 Sig caliber. That got me thinking about the 10mm. In general, what would be a better caliber to get, a 10mm or a .357 Sig? In my friend's case, he will use it primarily for home defense and range use. Any suggestions for a particular handgun and ammunition will also be appreciated :)
 
Honestly....from the criteria listed....neither. Not bashing either cartidge, as i have multiple guns in multiple platforms for both, and I'm a big fan of both.
 
If they prefer a 1911 the question should be 10mm or 38 Super (whose ballistics are nearly identical to 357 Sig).
 
I'd say the sig for home defense over penetration might be a problem with 10mm that being said id make sure I had good hollow points for the sig
 
I would also say neither. For the stated purposes, I would select a more widely available and less expensive alternative caliber....that is unless he plans to reload. Also, if hunting or defense in the wilderness were other potential uses, then I would say 10mm.

Nice thing for me about the G20(10mm)is that with a 40s&w conversion barrell you can shoot that caliber as well, using the same magazines. Gives flexibility in ammo choices.
 
10mm. I think there are more options available in 10mm and I notice a trend in increasing popularity of the 10mm vs. Sig 357. If the trend continues, ammo, supplies, pistol choices and accessories would continue to be more available for this platform.
 
I voted 10mm because that is what I am wanting for my next semi pistol, probably not going to be a Glock. Geater ammo choices is another reason but I am thinking 357 Sig is less expensive or at least it was the last time I checked.

I had a Glock 24 that I bought a 357 Sig barrel for and played with it for a while. Never could fall in love with it for some reason, traded it with no regrets.

You can do the same thing with the .357sig models. But you can also step down to 9mm with a barrel and mag change...
 
The G20 can also be converted to shoot 357sig for that matter.

If he reloads, the 357sig is pretty cheap to roll your own. Lots of once fired brass out there for cheap. 10mm brass...not so much.

Realistically you could get the G20 and with new barrels shoot at least 3 different calibers through it. Heard there might be a .22tcm conversion in the works too.
 
I don't like either cartridge as a "house gun" round, but if pressed, I'd go 10mm due to its versatility.
You can load light and fast, heavy and fast, and everything in between.
357 SIG is limited to specific bullets in a small window of weights and dimensions, and I wouldn't mess with it in any case.
The only argument for the SIG is that smaller guns can chamber it, while you must use a large frame for 10mm.
If I were going to a small frame gun, I'd go 9mm, +P+ if necessary, for the larger capacity.
 
For those of you who don't like the 10mm for home or range, but have one, what do you do with yours? I never thought of it as a particularly good hunting round or do you effectively hunt with it?

Assuming the OP chooses one of the Glocks (G20 or G29), he can, in theory, shoot 4 other cartridges by just swapping out barrels: 10mm, .40S&W, .357Sig & 9x25 Dillon.

Swapping out the G20's upper for that of a G21 would allow him to shoot .45acp off the G20's frame.

Then there are the large-frame .22-kits for the G21 & G20.

The Glock 10mms are as versatile as the 10mm cartridge itself.

Word ... :cool:
 
I use mine mostly as a "fun gun".
I shoot some IDPA competition, entertain myself with load development for its own sake (how much faster does it go when I add .2 grain?), and I'm a 1911 junkie that didn't need any convincing that the Delta Elite is a GOOD THING.
If I were going for a hike in the woods, I'd probably carry the Delta in preference to any other handgun I own, due to its size/power ratio and ease of handling.
The 10mm round will do just about anything that any other round, between 9mm and .357 Mag will do, so for someone who needs a good excuse to buy another gun, a 10mm will serve a whole lot of handgun niches.
If I really took that to heart, I could easily get rid of six or eight of my handguns, and use the Delta to replace them all.
 
I agree with just about everyone else- for home defense these are terrible calibers. But just in terms of general awesomeness I'd advocate for the Sig. I have guns chambered in both and I'm consistently thrilled with the results from my .357 Sigs- both of which are pretty short barreled. And the ballistics are far superior... Here's some screen shots showing comparisons from Federal's ballistics program. Which, on an unrelated note, I'm effing addicted to.

Banger I'm no expert in either of the calibers--but looking at your ballistics chart it doesn't look to me that it's a realistic comparison--the 180 gr 10 mm looks like an anemic load--you push that up to the warmer side of 1200+ fps and your kinetic energy should significantly increase from what is here I believe.
 
To me ... not much use for either. To expensive to use as a range gun. Also not needed for defense. You can get higher capacity, and way cheaper and more readily available ammo in 9mm. As well as more than get the job done in a defense situation.
With that being said... I would consider a 1911 chambered in 10mm for hunting deer sized game at closer ranges
 
That's definitely a possibility Stag- this is Federal's program and I like it because it is really easy to get quick, easy to read comparisons. But of course it is limited to Federal's product line, and they don't have many offerings in the 10mm. Most of my 10mm has been hand loads or DoubleTap defensive rounds, which are probably higher pressure than these.
 
Definitely neither round for home defense. Both rounds are very loud, and both produce a lot of night vision-killing muzzle flash. Two distinctly suboptimal choices for home defense, in my opinion.
 
split the difference. 9x25 Dillon. 10mm Auto Necked down to 9mm. :cool:


.357sig would be a better choice for SD, over the 10mm auto IMO.
