10 Mm That Much Advantage Over 40 Sw.

The hottest commercial ammo I can find is from Double Tap:

Caliber : .40 S&W
Bullet : Speer Gold Dot
The 180gr Gold Dot @ 1100fps from a Glock 23!
1050fps 441 ft/lbs from a 3.5"bbl.
1140fps 520 ft/lbs from a 4.5"bbl.
Ballistics : 180gr. @ 1100fps / 484 ft/lbs- Glock 23 (4.0"bbl)

Caliber : 10mm auto
Bullet : 180 gr Speer Gold Dot JHP
Ballistics : 1300fps 676ft/lbs- Glock 20
Glock 29 - 1240fps

Caliber : 10mm auto
Bullet : 200gr Controlled Expansion JHP
Ballistics : 1250fps / 694ft lbs. muzzle - Glock 20
1083fps / 521 ft lbs 100yds Glock 20
Glock 29 - 1195fps

Momentum of the 40 S&W = 1140 x 180= 205,200
Momentum of the 10 mm = 1300 x 180= 234,000
Momentum of the 10 mm = 1250 x 200= 250,000

One additional option with the 10mm is heavier bullet weights in commercial ammo.

You decide.

I was thinking of getting a dan wesson down the road.but already have m@p 's fullsize and compact in 40 sw. mainly for cc.
 
Double Tap creates ammo that realizes the 10mm's potential.....like 165 gr loads over 700 ft/lb.

Hand loaders can do the same.

Many commercial manufacturers make 10mm ammo that is really not that much different than their .40 offerings.
 
The trouble with DT 10mm is they use bullets designed for optimum performance at .40 S&W velocities. Pushing those bullets to the velocities to which DT pushes them usually results in less than optimum on-target performance. There is a whole lot more to effectiveness than MV/ME (and that is not even addressing issues like shootability--i. e., speed and accuracy of follow-up shots, recoil, muzzle blast, etc.).the
 
I've got about two cases of DoubleTap 10mm ammo and I have been nothing but pleased with both it's accuracy and it's performance in inanimate objects such as tree stumps, ice/snow berms, water jugs, etc...

I'm not sure that many people would be able to provide an objective viewpoint of DT's performance as not many of us TFL folks shoot people on a daily basis and I'm unaware of any official testing by any LE Agency or independent 3rd party of DT ammo. I'm also unaware of any LEA that issues DT ammo...

If anyone could provide supporting data for juliet_charley's opinion, I would be very interested to know it's content and source. I understand that not everyone can shoot the 10mm accurately, quickly, and so on... But those of us that can have a much more powerful handgun than 9mm/.40S&W/.45ACP/.357SIG shooters. Hands down, no if's and's or but's. That is a fact.
 
... and the ? still stands: For what purpose?

For SD against 2 or 4 legged animals, trail gun, night stand gun, ext.
 
A friend was having some minor issues with his Witness so I tweaked it up for him and then took it to the range to function test. All he had was some of the top-end Double Tap so he gave me a box of 50 and said "have at it".

I was actually kinda surprised at first with the 10mm (my first time shooting it) but I'm a fan of the .40 S&W and have shot a lot of .357 magnum in my time so I settled in pretty quickly and produced a nice grouping.

I'll have to tell you though, 30 rounds of that hot Double Tap shot pretty rapid fire to test the gun's function and my wrists were basically done for the day :D

10mm is a beast even in something as heavy as a witness. I'd hate to see it in a lighter gun!
 
mrt949:

A ccw is a very personal thing. I suggest to pic the platform first then the caliber. Remember you want a small and light weapon for comfort & convinience. A 10mm in a small weapon can be a wallop.
 
I won't ever get rid of my 10mm. Then again; I won't ever carry it concealed, either. My old stock of Hornady 155's are marked "1410 fps" right on the back of the box, and they feel like it. Look up the new Hornady 155's, and you'll see they're marked "1286 fps". Thanks a lot, wussies. ;) The 200 grainers are where you see it really move out front. You can't do that with a "shorty forty", but they do carry a whole lot easier. The very same thing is true for my revolvers. A great 6" .357 mag. is totally awesome to shoot all day long, but do you want to use a fire-breathing dragon that pulls off your pants for you for CCW? "Where's the beef?" -7-
 
Unless you have joint sensitivities, I don't see how shooting lots of 10mm ammo can cause pain.
About 15 years ago when I was in my forties, I shot about 1500 rounds of 155gr @ 1350fps while attending Gunsite going through the 499 course (five and 1/2 days). A couple of the people commented that they noticed the muzzle blast standing next to me on the firing line. That load sure put down the Pepper Poppers fast. It helped me hit at ranges over 25 yards because of its flatter trajectory too. I impressed one of the instructors by knocking down a Pepper Popper that was set backwards (it was not supposed to fall over) at about 40 yards.
 
Mello2U,

I also forgot to add that just like my very first .357 revolver experience was, the 10mm is at the top of my list on the autopistol side for a "must have" in a young shooter's life. :D -7-
 
a7mmnut,

My first purchase of a center fire handgun was a S&W model19 in 357 magnum. Now, my choice for personal defense is Colt Delta Elite in 10mm auto.
 
Thirty percent more power.

Does it recoil thirty percent more?

Or do you 10 mm owners find shooting your 10mm handguns ,not that bad.

I'm used to shooting a 357 mag no problem.

10mm reads like the big dog on the hill as far as semi autos go for cartridges that are commercially availible.

It's simple. Some people (myself included) just don't take heavy recoil well.

Fully loaded 10mm can have a pretty stiff recoil and anyone considering a 10mm should be aware of that. Might be no problem or might be a deal breaker.

To my surprise, I was actually fine...until I did an as-fast-as-I-could-shoot-the-gun function test.

The cumulative effects of of slamming through three mag changes without a letup left me with a definite tremble in my hands by the time I was done (but I verified that the gun would now run :D ).
 
The 10mm is well worth it and, in my opinion, is probably one of the best calibers available for a defensive pistol. After years of shooting everything I could get my hands on and just about every caliber imaginable, I settled on a 3rd gen. Glock 29. I wish I had found both the 10mm and the G29 sooner.
