Pain in the ass to instruct/teach compared to most modern duty-weapons. If you want me to teach 15 people that have never fired a pistol in their life, please, please, please don't give them a 1911.
Put those same 15 shooters on line with a 1911 and have them do drills from the 7-25. Then those same 15 shooters do the same drills with a Glock/M&P/XD. Watch how many alibi shooters you have in each group.
Sooo, you're saying the Glock/M&P/XD pistols are better choices for inexperienced shooters and cops that don't know crap about handguns?
