Any of y'all have any experience with either of these cartridges in a full size Glock? I'm considering purchasing either a G22 or G31. I'm fairly familiar w/ Glocks, but have never owned one, so I've been doing some research and reading a bbs called GlockTalk. Apparently there is some concern re: KB's due to the Glock's unsupported chamber, particularly in the higher pressure cartridges. If any of y'all own Glock's, have you experienced any problems with these cartridges, ie. failure to feed, extraction problems, signs of excessive chamber pressure (case swelling/bulging), the pistol blowing up in your hand? How would you rate the Glocks in terms of reliability?
