.45 Glocks

Are .45 Glocks as durable (long lasting) as the 9mm Glock counterparts? I read in the 1999 Glock Annual of a 140,000 plus round G17 9mm Glock still going strong. But, I have never seen studies done on .45 Glocks-- which are my favorite caliber in Glocks.
 
Operating pressure of a 45 is much lower than a 9mm. Velocity of the slide and of the bullet are reduced. I don't know why the gun wouldn't last as long if not abused.
 
Not only are the glock 45's as good as the others, but if you have big hands they are MUCH BETTER. and MORE ACCURATE. the riflings are octogonal instead of polygonal. they are a little thicker than the 9mm/40/357sig counter parts, but every bit as reliale and more accurate.

i have a glock 30, and it is as or more accurate than much larger guns, and my Sig p245, which is for sale by the way.
 
Quantum; Come to think of it I've never seen any write ups on long term durability or reliability of the Glock 21 either. I've had mine since '96 and have shot maybe 5,000 rounds though it. No breakage or malfunctions of any kind so far. I'm not sure I'll ever put 30 or 40 thousand rounds though it. IMHO, I believe there's just as much stress put on a 45 as there is any other pistol because of the heavier bullet. I think a 45 would be "battered" just as much as a 9mm over the period of say 20,000 rounds. Best Regards, J. Parker
 
Actually, my shootin' buddy and I are going camping next week and I'm going to give my G-21 a good workout.I'll shoot it right hand weaver, right hand only, left hand weaver, left hand only, double taps and triple taps. If it doesn't choke shooting left handed (weak hand) it's a keeper! :) Best, J. Parker
 
If it chokes shooting weak hand, don't "off" the gun, start doing some curls to build that wrist. Massad has written often on the value of weak hand shooting > if you're serious about your defensive training, you should include it every time you go out!
 
thanatos; I whole-heartedly agree with you. When My buddy and I go shooting I shoot almost as good weaver lefty as I do righty. But my buddy won't even attempt left handed shooting. What's really challenging is shooting left handed (weak hand). The true definition of "limp wristing" is shooting one hand, weak hand. Best Regards, J. Parker
 
I have 2 G21's, one old, one new, with about 45,000 rounds between them. Broken parts so far, both trigger reset springs on both and an extractor on the newer one. Replaced parts so far, both recoil guide rod assy and springs with Alchemy captive rods and ISMI springs, all mag and reset springs with Wolff springs, and aftermarket barrels, Federal and AccuMatch, for shooting lead. Other than holster wear, and nicks, thats it.

Well I have small to medium sized hands and I too love my Glock 21. The grip feels very good to my hands. I get groups the size of a quarter out to 15 yards. There is usually one flyer-- but I discount as the exception, but I believe thats more of a magazine problem than gun problem. A 45 that puts 9/10 rounds in a hole the size of a quarter is really hard to find, and my 21 can do that. My only concern is the lack of durability tests done on the .45 models.

My other concern is Kb's-- I hear .45 Glocks are suseptable to Kb's more than 9mm Glocks.
 
Quantum, for a really intelligent and well documented discussion on KB's, do a search for posts by MarkCO.
 
To slightly change the topic, anyone know why the .45 Glocks are so much more accurate than the other caliber Glocks? I know .45 Glocks use octagonal rifling and all other Glocks use hexagonal. But is that the only reason for the improved accuracy?
 
Hey QS, did you used to post on the Rogue forum years ago?

Anyway, the Glock 9mm in question is now up over 200,000 rounds without more than a chipped extractor IIRC.

There is supposed to be a couple Glock 9mm's at the factory with well over 750,000 rounds through them.

The .45 is a bit more powerful, but it is also a beefier gun with more slide mass etc. Think of it this way: the .45 is the weaker round for the design, because the 10mm is far more powerful. So, shooting the .45 through a gun designed for the 10mm means you are going very easy on the gun. I predict it would last a veyr long time. My Glock 30 has given me no problems, but I only have a few thousand rounds through it. It can print an inch at 15 yards as well.

The Glock 30 in particular is extremely accurate. Some say it is the recoil setup. Some say it is the stout, stiff barrel.
The width of the frame and the polymer also eats up a lot of recoil, so the Glock 30 has VERY light recoil.

I have not found my Glock 21 to be as accurate as my Glock 30, but it sounds like yours sure is!
 
The .45 Glocks are quite durable. The only problems I have had out of the 21 and 30 were both due to shooting semiwadcutter bullets.

That resulted in chipped extractors and it was quite simple to replace those.

I have played with the springs, etc, on my Glocks and now use a 22 pound Wolff recoil spring, a standard striker spring, and, on occasion have used the Glockmeister competition trigger spring. These additions, along with a 3.5 pound connector with a good polishing job on the components yield a darned good shooting gun.

I like a light trigger. That being said, I tried the reduced power striker spring along with the GM competition trigger spring and the 3.5 connector. It was too light...even for me. That is why I go with the springs mentioned in the above paragraph.

No, I never posted on that forum (I don't even know what forum that is). But I do still post on occasion on the AOL Gun Talk forum. I think you helped convince me to get a Glock 30 as a backup to my 21.

I plan to get a Glock 30 soon! I like the accuracy potential of that model.
 
If you like Glock and the .45 ACP, you will love the G30.

Compact, Powerful, Accurate, and Reliable.
 
I hate to get into semantics, but octogonal is polygonal. Octogonal simply specifies that there are eight flats.

I haven't shot more than 300 rounds through a G21, but if you can accept the Glock grip angle and have big hands, it's perfect. If I hadn't run into a CZ-75, it would have been my first pistol.
 
Destructo6; I knew it, you're a west coast kind of guy. Things get pretty quiet this time of night. I'm here in Wash. state bouncing back and forth between TFL and GlockTalk and there's not much happenin' Best Regards, J. Parker
