Last night I bought a Gen 3 G20.  I've always wanted one but was afraid I couldn't handle it.  I can very accurately shoot my .45s one handed, but last year I bought a G23 because it was slimmer than my G30SF.  BIG mistake!!!!  Even with a lot of practice I simply could not handle the "flip".  Those of you who shoot .40s will know what I mean.  So I finally gave up and sold it.  Everyone I talked to said that if I couldn't handle a .40  I'd NEVER be able to handle a 10mm.  So for a while I just stopped thinking about it.  Anyway, last night I was at my local gun shop and there it was...a G20.  So I went to the range counter to find out whether they had one to rent and they did, so I thought, what the hell, I'm going to give it a try.  I was shocked!!!!  It was a pleasure to shoot, didn't have hardly any "flip" and so I bought it.  Does anyone know what the differences are between the .45 and the 10mm?  I know the 10mm has more powder and is faster, but in real life situations I don't understand what that really means or if its more powerful or has more knock down power than a .45?

Congrats on your new pistol!  My 20 is much softer shooting than my 23, but the 23 is far from difficult to shoot with the proper grip.

The .45 is great for two-legged critters; the 10mm is "more powerful", shoots flatter and penetrates deeper making it better for hunting situations. As far as knockdown power against a human being, I doubt you could really tell the difference but the .45 does have a stellar reputation and you could argue that it's the better choice as a self-defense type of gun. I was like you, always wanted one but wasn't sure about the recoil. Bought one about 8 months ago and absolutely love it.

Please show me the data supporting the "stellar reputation" of the 45 ACP. All of the facts I've ever seen say the same thing: 9mm, 40, 45, even 10mm - they're all mediocre "man stoppers" at best, and there is no such thing as "knockdown power".  Handguns are not particularly effective, but they are a lot easier to conceal than an AR15.

This!

The 10mm gives you better penetration and flatter trajectory.  Both can be an advantage in a hunting situation.  For self defense against two legged creatures it's actually at a slight disadvantage because there are not many choices for loads with modern bullets.  You have to go boutique to get a load with a Gold Dot bullet and you can't get a Ranger or HST bullet in a 10mm

I have a G20sf and it's my carry gun in the woods.  I make hot loads using 180gr Hornady XTP's since it's more of a controlled expansion bullet.

Congrats! I just bought one myself last week. And my underwoods ammo just came in a few days ago, I cant wait to go take mine for a spin!

If I used a 10mm for defense I'd use a very moderate load like a 190@1000. No point to more unless you're hunting.

I purchased some .40 HST, 180gr ammo. Used a bullet puller....voila, 180gr HST 10mm after hand loading them into virgin starline brass, fresh magnum pistol primer and a nice dose of blue dot.

I've tested a few 10mm defensive loads and peneteration hasn't been an issue (any more than defensive 9, 40, 40SW, ect...  loads)   Here's a test of the 155gr Gold Dot load from Underwood with under 14'' of penetration for example:

2/1/2013 3:40:23 PM EDT
[#12]
It's my understanding that gel studies have shown that the 9mm penetrates just as deeply as the more "powerful" rounds...40, .45, 10mm.  However, the bigger rounds produce larger channels, which hypothetically would equate to greater tissue damage.
2/1/2013 7:20:39 PM EDT
[#13]
Not really. The 10mm penetraits almost 21" with Underwood 180gr where a Underwood 147gr only penetraited 11.8"  Thats way more than most other 9mm ammo.
2/1/2013 8:16:53 PM EDT

Hot Underwood ammo is the SHIT !!!!! Factor in the speed this 165 gr bullet is traveling at 1400 FPS and energy delivered 718 FT/LBS Add in longer barrels and everything just goes up If it works on Grizzlies then I like it

Might as well just shoot a .40 or 9mm and use a smaller gun. There's no point in using light loads in 10mm for defense.

Sure there is. The G20 is a softer shooting and more reliable gun than the G22.
2/4/2013 9:52:10 AM EDT
[#17]







The OP's comparisons between the G20, G23, and G30 are
meaningless without specific ammo information.  I own a G20L, 21, G21L,
22, 23, and 24 and his comparison between the G20 and G23 means nothing without
the specifics of the ammo used in each platform.  I handload everything my
pistols eat and I can load hot 45acp and mild 40s&w, mild 10mm and hot
40s&w (however, why would you?), or anything else I want so a blanket
statement the OP makes without specifics is plain nonsense.
I suspect that the 10mm ammo he shot was generic commercial type while the
40s&w might have actually been hotter loads.  Bullet weights and
powder burn rates have a marked impact on the perceived recoil in one's pistol.
 My G23 is my CCW weapon and it eats hand loaded 180grn Speer Gold Dots
(1050fps) using Power Pistol powder as it's single diet.  Those loads have
less muzzle flip than 165grn 900fps loads through it using TiteGroup
powder in part because of the type of recoil impulse generated by the large
differences in burn rates of the two powders.
One needs to remember that the difference between the 40s&w and the 10mm is only peak chamber pressure.  Both calibers can shoot the exact same bullet, both could shoot them at the exact same velocity too.  Unless one does a systematic analysis, rash statements like the OP's and some of
the other posts such as the nonsense below saying that the 10mm round is softer shooting than a 40s&w round are simply silly.

Add to that the statement above that the G20 is more reliable than the G22 and one soon realizes that much of what is said on the internet screams to be taken with a grain of salt at best and completely disregarded at worst.

The G20 doesn't have the slide velocity issues that have caused 8 revisions of G22 magazines, the FBI to use downloaded Speer Gold Dots and Glock to design the 4th generation Glock.

The real advantage in 10mm is the versatility of the round. It can be downloaded to .40 specs for moderate shooting, or it can use a hot round for killing large 4 legged animals.

G20>G22 all day long.

My gen 3 G22 has well over 27,000rds through it with absolutely no issues at all.  My 180grn GD loads at 1050fps work just fine in my G22 too. Many LEOs may carry firearms but have no idea how they work, nor how to even clean them.  The real issue is that the Glock, like most mechanical items made since the beginning of time isn't completely idiot proof.

You don't think that 9 minor or major design changes to the pistol and one to the ammunition indicates that the weapon is perfect and the only issue is with the operators? Really?

I'm glad your gun works. People who use enough of them to have a statistical sampling have found a problem. The manufacturer has gone to extreme lengths to get them to work with a light.

Light loads from a G20 are very soft shooting too.

Got my 20sf mags loaded with 155 Hornady XTP.  Found them at the LGS next to the 10mm Hydrashoks.  I know the Hydrashoks have fallen out of favor to the more modern bullet technology, but then again I don't hear too much about people using Hornady self-defense ammo here either.  The price difference between the two brands was $15 for the same quantity of rounds, so the choice easy anyway.

Sounds like Underwood has ammo in stock despite the panic.  Will have to order a few different loads!

So the .40 S&W has more recoil than the 10mm?  I ask because I have a S&W M&P 40 on order and I'm curious what to expect.  I've always heard the 40 has a much snappier recoil than other common calibers and that's why it's appeal has wained since being introduced.  I've got 9mm, .45LC, .45acp, .357mag and .44mag...which one of these would compare closest to the .40S&W?  I've also got a G20 on my list of wants so I'm surprised to read the .40S&W has more recoil than the 10mm.

I have a buddy who has a 10mm.  I've shot it a few times and have really liked it.  Very little recoil and easy to shoot..... kind of like my 26, 19, 17 and all the other glocks I've shot.  The only Glock I really didn't care for was the 27.

The .40 got its reputation from the underweight Glock 22 with its high slide velocity. Compared to the G20, it kicks harder. The G20 is significantly heavier, has a heavier spring and a wider grip. In like guns I'd expect the 10 to recoil more. An M&P40 will recoil less than a Glock. The softest shooting centerfire pistol I've ever fired was a 2011 in .40 caliber.
