Glock & +P; +P+ ammo?? What does Glock say??
So this came up in another thread, and it's come up several times, so I decided to call the US "Assembly" plant in Ga today and find out first hand.

I talked to Darrell(Darryl) who was in tech support and asked specifically if there was a problem removing ANY Glock pistol from the shipping box and feeding it either +P or +P+ ammo.

His response:

Next I asked if they recommend upgrading any components like a recoil spring for someone that might want to carry these rounds exclusively and practice with them at a rate of two range trips a month.

Then I asked him if there was damage to the weapon and a customer sent it back with full disclosure that they had indeed been shooting +P and/or +P+ ammo in it, would this void the warranty or otherwise affect the level of service they received. This answer was a little less definite.

"So, Glock may question if the end user was handloading and this caused the problem?"

So, there you have it folks. Right from Tech Support in Georgia. You can shoot the hot stuff through your Glocks, but make sure and change your recoil springs frequently and have your data books up to date with the ammo you used just in case.

+1 for Glock on this issue.
