I agree with Madhatter1. Most likely the ones being used for training already were in action. I'm former 0311 myself. But to be honest didn't spen a whole lot of time behind the 249 personally. Night shoots with tracer rounds are a blast to watch. Good luck
Look I like glocks. I've owned Sig's, HK's, 1911's, S&W, and other fine pistols but Glocks have been a favorite for me. Handguns without safeties are not dangerous. Idiots are dangerous.
