Well, the Beretta Brigadier kicked the SIGs butt in the INS/BP T&E for reliability. Glock too. Much tougher T&E than the FBI or USSS too. They issue the Beretta, the SIG is an approved option, the Glock is not. They will start issuing USP compacts to plainclothes agents if they haven't already. Last ammo contract was split between Rem/Fed for 155 JHPs.
The Glocks, USPs, Walther P99/SW99 and sig pro are pretty damn tough. The alloy framed Berettas and SIGs are too close too call IMO, and the steel frane S&W 4006s have been holding up well. Very few people are gonna shoot any of em enough to wear em out; anybody who can afford that can afford to replace them?
Have seen/heard of kBs in all of them, but the Beretta and Glock are the only ones I've seen rupture the barrels. They also have the thinnest chamber walls and least amount of case support. The others blow cases and keep on going...
