At least the M9 has BTDT. Ditto for the SIG P226 with the SEALs. The B92 saw plenty of mud in the joint service pistol trials. It's not Beretta's fault that only the SIG P226 could keep up with it.
When I was in the service, all the 1911A1s were clapped out. That's the way it goes with community property. The services were not expecting to go 40 years between acquisitions this time. There has been a series of M9 contracts, not just the one. Clapped out M9s should see the crusher after being stripped of serviceable parts.
The HK is the ultimate gear queer weapon--a lab tested range queen with no actual combat record. That might change someday, but no H&K model has proven itself where and when it matters save the crew served Tactical that not even the SEALs who adopted it like very much.
The Glock is picking up a little bit off of being a mere "cop gun" by seeing varied service in Iraq.
CZs are widely used across the planet, but not by anyone who actually seems to fight.
The SIG P228 soldiers on, mainly in aircrews.
If any of the above, from the 1911A1, to the latest HK lab rat, were saddled with crappy low bidder Checkmate magazines by the DoD's bean counters, their reputations would all suck.
