O.K. guys-talk me in or out of 10mm

The difference is only 1mm

take a look at a metric tape measure . . . . how much is 1mm . . . ask yourself . . . is it worth it for so little more???

9mm is generally available - price is great for practice - 1mm extra is not going to make that much of a difference if the BG is hit in the right spot. 1mm extra is not going to make that much difference in stopping power

..........wow.........I don't know what to say to that

maybe someone else can straigten this guy out

1mm

That is really a narrow view of guns and bullets.

I think you should become a .40 S&W fan like myself. Its a magical compromise with better velocity and the same knock down power of a .45 . The only better rounds are those that are too powerful for auto loaders and thus not too practical for CC.

I am pretty sure that 10mm is virtually the same as .40 cal. If you put the two side by side I could see loading the wrong one. 10mm is becoming less and less common which usually means more money. I like 9mm myself but i like to shoot alot and 9mm is dirt cheap (about 15.00 for a box of 100 at wal-mart)

It's not the size of the bullet, it's the ballistics.....115 grain 9mm- 1100fps;390ft lbs energy.....180 grain 10mm- 1150 fps; 550ft lbs energy; and then there's Doubletap 10mm ammo 165 grain- 1400 fps; 725ft lbs of energy.. and the 40S&W is just a shortened down loaded 10mm

actually 10mm is gaining popularity for the reasons i've given...better ballistics

All good ammo is expensive.

My G20 is about my favorite...but I like my other DOA calibers: 9X23mm Winchester, 38 super and 357 sig (all dead I guess).

Start with a G-20 (Used to be Glockmeister's [Mesa, AZ] favorite caliber/gun)

It's a great caliber, but then again, I like another dead one, 41 magnum.

Here is a pict from the Shot Show. The Delta Elite is back!!!

I think the 10mm cartridge, and particularly the Glock 29, is a truly fantastic platform. But I'm not against carrying 9mm or .45 ACP either.

Heck, they're all handguns. No "magic bullet" exists when it comes to your sidearm.

10mm is nice, but, it sort of starts running out of case capacity when the bullets go over 170 grains or so. 45 ACP, or better Super, is really nice, because some of us feel 230 grain HP's are sort of the minimum for SD use. Faster you push them, sooner they open up, so it's hard to get adequate penetration with lighter bullets, same with the 10MM.

Now if we can get 260 grain 45 cal bullets, at 950 fps, we'll pretty much equal the 45 Colt. What progress...

Id say just the opposite the slower heavier projectiles tend to penetrate less. 40 S&W is the one notorius for deep penetration along with its big brother the 10mm.

Actually in all my trauma training we are more concerned about velocity that mass. Both are important but we square velocity times .25 mass to get kinetic energy. The exception is knife wounds which can be more deadly longterm speaking that gunshot wounds.

That looks like this for you scientific guys:
KE = 1/2 M V2

KE is kenetic energy
M is velocity
V is velocity

O.K. DON'T buy that 10MM. You don't need to spend the money on another gun. Instead, pick a couple friends on THR and let THEM spend the money and you just go to the range and shoot theirs.

I have owned a delta elite now for about 15 years, have yet to fire it. it is one of the few guns i own that i havent fired. think i'll just continue to collect this one. have three 45 auto's, one 40's production colt, one 1991 a1, and an officers model. love the shoot all of these.

Glock 29 and I love it. Small and makes a good bang. Not that bad on recoil, but you know you are shooting something with some balls. I am not sure about accuracy compared to my Sigs, but it does make a strange huge hole in the paper targets like nothing else.

I dunno if the 10mm is really undergoing a revival, but it's a cinch there are more 10s available now, over the last year or two. There's even a thread on the Bren Ten being revived.

You can read about my experiences with a Kimber STII 10mm and the EAA Witness Elite Match 10 mm here.

I've always liked the 10. Just never got around to buying one. But then I'm also a 41 Mag fan, which I do own. Go for it, I envy you.

Dreged thread, should be in autoloaders anyway
A 10 would be great in a 5 shot L frame.

The Main reason I do not like the 10mm, is it has become the odd man out caliber. Self defense ammo is expensive and less choices. Honestly looking at the research, the .40 and .45 are a little better stoppers anyway. I am a big .45 fan, all of my .45's are Hi-Cap Mags 12 and 13 rounds. So Mag Capacity is not an issue. I am actually starting too lean towards the .40 because practice ammo is so much cheaper and I do not reload. Ammo choices for the .40 are very good now, because it has become THE Law Enforcement round. A lot of SWAT teams and Special forces lean towards the .45 for a side arm. I do own several 9mm's and in all honesty I would choose 9mm over the 10mm because the choice of guns is so much better and ammo is less expensive and ammo choices are Excellent. Also the 9mm has become a real very good stopper because of Modern Bullet Technology. So as you can see I rank the .45 and .40 dead even as the Best to me and the 9mm a close second. I would even put the .357 Sig ahead of the 10mm because of the choice of guns and ammo cost.

The Best to You and Yours!

The 10mm round is extremely versatile! It's worth the money, imo. You can have rounds down to being as weak as the .40 S&W (Short & Weak), and a round more powerful than the .357 Magnum! Even approaching the power of the .41 Magnum!

DT has 10mm ammo that penetrates far, and expands wide (1.2 inches!)!

You can easily use the 10mm for self defense DEPENDING ON the grain and load you buy / make (a lot of 10mm ammo is watered down on the market, except DT's 10mm, it's hot!). Then use the hot loads from DT for hunting, taking down medium, and I'm reading about Ted Nugent taking down large game in Africa with his Glock 20!

Now, when you can actually put such versatility to the test, you'll soon see why it costs just a bit more (come on, not that much, like at Georgia-Arms.com... $13.70 for 50) to buy.

You can always start reloading, but make sure you buy an aftermarket barrel, since Glock barrels don't like lead bullets flying through them compared to others. Buy a 6" barrel for hunting long range, too!

I've asked around, and though I know it'll be a chore, it's not impossible: The Glock 20 is concealable! Just got to get the right holster, and clothes to fit.

I'm willing to make the sacrifice! For 16 (15+1) rounds of 10mm in the Glock 20? How could I resist!

If only glock came out with a compact frame for the 10

I agree. I think GLOCK should've made a Compact 10mm first, and then Sub Compact (G29) later on. The current Sub Compact G29 is roughly as long as the Compact G23, G19, G32, etc., but it has a shorter grip; if they just lengthened it about 1/2 an inch to fit a few more bullets in (so it could carry maybe 3 more), I think it'd be more attactive than it is now. Though, I'm still buying the G29 after my G20, anyway. I always like backup, even if it has but 11 round (10 in magazine, 1 in chamber) capacity.

Frank or anyone...

Can you post a reference to where the research you hint at exists. I have never seen any research like this.

And I am not being a smart rear end... I do want to see this research.
