Civility. This is an objective discussion about gear, not our children.
Boris, thanks for that info on PDs and the GAP. Bear, I don't disagree re PDs, BUT we are really discussing acceptance and the market, not the merits of a cartridge. Hell, our military shot down the Brits' .280 cartridge of the 50s in favor of the 7.62 NATO, then we went to the 5.56 NATO, and guess what? We're finding the .280 was a great choice because we are sniffing in that direction. Regardless, sales of firearms in 7.62 and 5.56 are driven by military acceptance just as sales of civilian handguns are quite driven by "what the police use". The .45 acp and 9mm just happen to be very good cartridges, AND what the military and police use.
Most of the people here in this discussion, on both sides of the issue, are far and away more learned than the consumer. We are the minority and regardless of how good the 45 GAP is, if it isn't generally accepted and doesn't gets distribution, first through PDs, I don't think it will last as a major caliber. As for the Glock pistol, I no longer own one, now having XDs. My Glock 21 was as accurate as my Clark customized Series 70, and as reliable (at one third the cost and packing almost twice the capacity) but it felt terrible in my hand. However, the Glock is a great firearm, one of the top designs of all time IMHO. I should get a 19. My choice is personal due to "feel" and features subjective to me, accessories, spare parts, and familiarity (I like as few self defense firearms as possible so I know the go switches by instinct).
