The Beretta 92 is fragile enough in 9mm, the 96 is just not going to last too long. The SIGs have a much better reputation for durability particularly compared to most of the 40 cal pistols on the market.
Yeah that's my understanding also. They beefed up the slide on models like the Brigadier but they need to on all of them because I don't think we are even supposed to run +P loads either
