Both will work, and I have confidently carried both. My personal choice these days is the 10mm. A bit more horsepower and a couple extra rounds.

That, and I've always tried to be different in every way possible.
 
Another post. I have been reading eveything that I can locate about the 10mm, and specifically the Glock 20 and G20C. These two pistols are touted as being appropriate for hunting. But what caught my attention was one of the professional writers, who is a member her eat THR, stated that the Glock 20 is appropriate for 100 yards shots without significant hold-over on the target. Even the G29 was touted as a sure thing for 100-yard, human impacts. Wow.
 
45 has been used in the wars for 100 yd shots, the grease guns did it just fine. Thompsons also. Pistol will do it easy. Chest shot hits um a little low is all.
:uhoh:
 
Thanks for all the info guys and gals. After careful consideration, I am the proud owner of a new Glock 30. I am used to the .45 round and it will (and has) do all that I need it to.
 
I would go out on a limb and the 10mm is a little too powerful for self-defense situations where over-penatration is a concern.

There is so much concern about overpenetration yet most rounds fired in self defense don't even hit the intended target yet nobody worries about those full velocity rounds zinging around! Yes, I know that we think all our shots will be on target. It doesn't happen that way.

I'm a believer that deep penetration is needed to be effective. (See the FBI report on handgun wounding factors and effectiveness at http://www.thegunzone.com/quantico-wounding.html)

I have little worry about a round penetrating the target (it would exit at low velocity if I hit COM) and then wounding an innocent bystander. I'm more worried about the rounds that miss.

FWIW, I carry a .45 but I think a .357 or 10mm would be more effective.

Just my $.02

"FWIW, I carry a .45 but I think a .357 or 10mm would be more effective."

Agreed. In most respects, 10 mm will meet or exceed the stats of the venerable .357 magnum. Plus, there's the whole sixteen shots thingy, if you're talking a G20. :eek:

I shoot both .45 ACP and 10 mm, and I'd have to say 10 mm has the edge. Even the +P .45 ACP cartridges don't report like the potent 10 mm cartridges do! In 10 mm, I shoot Double Tap exclusively.

Still, humans are fragile creatures, and .45 ACP is more than enough for that kind of trouble.

I guess I'd say, if you're buying manufactured ammo, go .45 ACP. ;)

If you're getting into reloading, then 10 mm has it all! :D

As a woods/trail load, I'd also say 10 mm has the edge. :scrutiny:

Dgreno, congrats on your new G30! I love that gun--it was next up for me too! Note that KKM has a 10 mm Conversion Barrel for your G30, so you can walk on the wild side if you want to! :evil:

In reality the 10 is superior I'd have to think. 140 grain bullet going along at 1500 ft a sec and plenty of pentetration, where the 45 is pretty much never going to accomplish that part of the program. So I'll mention again it is the better if you are shooting through doors, or windows or clothing.
The bullet can be carried for the hunt to be specific. The Self defense side of it is similar. So if the 10 is better for hunting and doing the same thing for self defense what can be the reason? Lots of folks like the 1911 A1. My guess.

:uhoh:
 
.45acp V 10mm

With the Glock models you posted, I'd go with a Glock model 36 or 30 in .45acp, with a New York 1 trigger, ;). The 10mm is very powerful but bear in mind the Fish incident(research it here or NBC/Dateline). In short, A retired teacher named Fish, shot at a guy with a 1911a1 10mm. Some high priced "police expert" told Fish's criminal jury that "No US police agency uses the big bad 10mm." and Fish was then convicted. Boom full stop, end of story. :rolleyes: A jury member told NBC news; "I don't understand why he(Fish) used a jacketed hollowpoint."

The 10mm has had a bad rep for poor feeding too. Noted gun writer; Duane Thomas wrote a good item about the 10mm's use for SD/CCW/duty a few years ago. Thomas stated that the tip of the 10mm is not best for the semi-auto pistol's action.
Glock's 29 and larger 20, 20C are well made but for your uses, stick with the proven .45acp.
PS: Get some well made 230gr bonded JHP loads too, :D.

I have regretted trading off my Glock 20 for years. I love the 10mm round. Used to carry it when I lived in grizzly country, but traded it off when I moved south. Figured a 10mm full of 16 rounds of hardball may at least give me a running chance from a griz...
For human targets? I can get 300 fps out of a 3/16 ball bearing from a slingshot. That'll turn 95 percent of aggressors away.
However, 800 fps out of a 230 grain inverted ice cream cone will stop the remaining 5 percent in their tracks.
Love them both, but relegate 10 mm to back country.
Have to admit though, the 10 is a harder load to master as a reloader because it is kind of finnicky. Had to add a factory crimp die before reloads became reliable.
An aside - Once took a Glock 20 deer hunting just to prove it was an appropriate hunting handgun. Stumbling through the dark on the way to my stand an incredible 10 or 12-point buck walked right in front of me. I brought the Glock to bear on target and the night sights obscured my vision of the buck.
Turned out OK. Sunrise wasn't for another hour and it would have been an illegal kill if I'd dropped the hammer. Still wish that rack was on the wall, though.
Am looking into a 10mm conversion kit to fit my Tanfoglio .45. Complete slide assembly plus mag and it will shoot 45 and 10. Understand all I need to shoot 40 S&W then is a barrel and recoil spring.
Who says you can't have it all...
 
I like either, but carry the 10mm. One poster stated the 10 is dead. I beg to differ. It is growing in popularity ever day. Check out the offerings from Dan Wesson or Fusion Firearms.

The rounds are expensive but reloading is a very satisfying hobby, and a way to save a lot of cash on all calibers.
 
the .45 offers everything I want in a self defence gun, heavy powerfull round low to moderate recoil, easy follow up shots, large amounts of different rounds out there and every store you go to carries it. The big seller to me is that with a good quality hollow point you can diliver a huge amount of force with almost no chance of a pass through shot. When I can carry it (it is a bit large for tee shirt and jeans carry) I carry my 1911 loaded with federal 230 grain hi shocks.
 
I have owned a 30 but not a 29. For self defense against two-legged predators, I would still want the .45. The 10mm, loaded to its full power potential, is surely going to be quite a handful in this light gun, while the .45 with its softer "sharp push" recoil is very controllable. A full-power 10mm may also be overpenetrative, unless there are two or more attackers and they happen to line up one behind the other. ;) A reduced power 10mm has about the same power as a .45, so you have gained little there. I still say .45.
 
My vote is for 10mm as long as you load your own.

I've had both, a 45 in 1911 and a 10mm in Glock.

The 1911 seems to have a smoother recoil than the 10mm Glock (G20). I loaded my own 10mm, not the to the max load but just under. It kinda stung like catching a baseball with no mit.

FWIW... I own neither of these two calibers now. I've standarized my handgun selection to .40 S&W (G22,G23 & G27). I can control the .40 better then the 10mm and I don't have to worry about diminished mag capacity associated with 45/1911s.
 
The 40 cal is a similar designed bullet and is carried by LEO all over the USA. So I don't think feeding and ejecting is the problem, I believe it might be the facts of limp wristing the stronger recoil. Then you have a failure to feed. The noise is a biggie for some. Failure to feed can happen and does, murphy's law can be applied to that one:what:

I have shot both quite a bit, the 45 has been around a very long time. If that is what you prefer it is a good round for self defense.
If you want to hunt with a handgun many recommend revolvers with big powerful new and improved rounds for that enjoyment. 44 mag and above some will say. 357, 41 and 44 are all moderately popular and have been for a long time.
The 10 is one that is gaining in popularity though. It will continue to be avaliable from Glock, so if you like the firearm you can have both:)
 
The big seller to me is that with a good quality hollow point you can diliver a huge amount of force with almost no chance of a pass through shot.

If there is "almost no chance of a pass through" then it isn't a very good self defense round. Read the FBI report that I noted earlier in this thread. A round needs DEEP penetration to be effective. Add in the factors of possible heavy clothing, a bad angle or an arm or other bone in the way and any round that doesn't have enough power to fully penetrate probably won't go deep enough to stop someone.

Handgun rounds are all marginal. Yes, I believe the .45 is better than the 9mm, but the ,41, 10mm and .44mag are probably even better, especially if one is using hollow point ammo.

You really should go back and read more about the case, 10mm isn't what got fish convicted.
 
To me, If the ammo is only available at gun shops in few choices or isn't available at WallyWorld or other mass discount/department/sporting goods stores, guns in obscure calibers it are useless to me except as space fillers in my safe.

I'm culling all guns that don't use commonly available ammo. .45 acp is a better choice.
 
For self defense, I choose the .45ACP. Ammo can be found anywhere at decent prices for JHP and FMJ.

10mm.
I have a G20, and have used it with a 6" KKM barrel to take several deer.
IM0- a Big-Bore caliber in a revolver, is a million times better option.

Woods carry? I'll take a 4" 686 or 4" Model 29. I'll take SA revolver over the G20/G29

Non of the local guntores carry 10mm ammunition. They will order at higher prices, but will not stock. That leaves reloading or mail order.

For two legged threat the .45ACP is just fine. For four legged threats or hunting, there are better options than the 10mm.
I own the G20, to add to the collection. To me, the 10mm is a waste of time.
