Can you shoot 255 gr. +p .45 ACP cartridges in a Glock 21 at 975 fps, or is the pressure too high? My Glock armorer says that Glocks are "set up" for +p cartridges but forgot to mention 255 gr bullets in .45 ACP.

I don't think a bullet that heavy will shoot to the sights. It's gonna hit high!

From my experience with .45 ACP's 975 fps is a pretty warm load with 230's, and I'd imagine that with 255's it might be over the top. Since my religion is Orthodox Coward I don't want to be hanging onto a handgun that might go kaboom. I don't know of any 255 gr jacketed bullets either and if you fire lead bullets in a factory Glock barrel you'll likely have more problems.

Warning!!
Before you shoot it mount it on the bench and run a sting to the trigger and pull it from behind a tree!!

Pressure is pressure and +P is not bullet driven but, the pressure rating of the cartridge.
The 45 acp SAAMI MAP of 21K psi piezo, the 45acp +P MAP is 23Kpsi. If your pistol is +P rated you can fire any +P load that meets SAAMI guide lines regardless of bullet wt.
Be aware Glock is a Austrian maker and likely follows CIP instead of SAAMI standards. The CIP MAP is 19K psi and they don't recognize +P loads.
