After sitting back quietly reading the posts, I noticed a common trend; if you're going to get a glock, get it in 9mm. This raises a question...
Is it because of the Glock's design that we should only get a Glock in 9mm? I have heard from some Glock owners that because the Glock was originally designed in 9X19mm Parabellum, the glock isn't guaranteed to perform as well in other calibres (ie .40 S&W, .45 ACP, etc) with respect to mileage and stability. This doesn't make sense, however, since Glocks are made in other calibres anyway. Can someone perhaps clarify if this is just a knock to make glocks sound bad or just plain bogus?
Big Red - I had not heard of Questar before. I got my 19's and 23 before the supply dried up. The mid-frame size does seem to be the way to go for best feel and "pointability" (whatever that is ???)...
Guys the issue of the Glock being best in the 9mm is quite simple. The envelope was designed around the cartridge. It performs best in the format in which it was designed. When the .40 S&W came along the big rush was on to get the first to the market and Glock (along with others) simply shoehorned it into the existing envelope. This often occurred without complete consideration of the added stresses - I know, I know... "but Glock has engineers and everything to sort these things out...". Yeah, right - and they are a profit driven company looking to grab a share of the market before anyone else. Not saying they didn't do all the requisite research, but not everything was known about the .40 that we know now. Things like bullet set-back from repeated chambering of the top round in the mag causing pressures to go all wonky and shoot thru the roof, causing what, you ask?? Well, turning the hand
gun into a hand
grenade (more or less)... Talk to any armourer from forces that use the .40 Glock about some of the things that happen with them. Not saying it's a bad gun, it just gives you extra things to consider.
Fact of the matter is that the .40 is a high-pressure cartridge that performs at a
much higher level (and consequently
much higher pressures) than the original format 9x19mm. In Gen 2 thru 4 of the .40/.357 Sig cal Glocks there is a reinforcing pin that runs transversly thru the frame in the area over the trigger - why? Because that area needed reinforcement after some use and the engineers figured that as the best fix without a total redesign of the gun...
I have seen personally, at the time of the event, or viewed the remains after, 5 Glocks that KaBlammed while shooting factory ammo. 4 of them were G22's in .40 cal and one was a G21 in .45 ACP. The G21 and one of the G22's were being fired by myself, both of these incidents being the result of the primer being struck with the slide out of battery causing a rupture in the unsupported case-head area. I know this is not supposed to happen, but there you have it. could have been a high primer, could have been dirt in the firing pin channel causing the FP to protrude from the breechface - don't know, couldn't recreate anything...
In both cases maintainance had been routine, not more that 3-400 rds since being field stripped and cleaned and absolutely no more than 1k since detail strip and clean. Both of the events resulted in the floorplate being blown off the mag, all the remaining rounds, the mag spring and follower and parts of the cartridge case being forcibly blown from the bottom of the magwell, and gas coming form the area between the slide and frame immediately over the trigger guard contacting the inside of the basal knuckle of my right hand. I suffered some burns from the G21 and a laceration from the gas coming out of the G22. Both of the pistols were sent back to Glock for inspection and Magnafluxing of the frames/slides/barrels with the result being that the G21 was returned to service unharmed, and the barrel of the G22 was replace at nominal cost due to being out of spec (slight bulging of the chamber).
The 1911 platform is
meant to be a .45 ACP, the BHP is
meant to be a 9x19mm, as is the Glock mid-frame. I'm not saying that they can't be made to work (after a fashion) in other calibers, but they will never be optimum in other than the original configuration...
YMMV
be safe,
