There is a HUGE discussion going on in the reloading room,on facebook. A fella has a brand new M&P from 'Smith,and when he inserts loaded mags the slide drops. A whole bunch of people say this is normal with 'newer' combat-oriented semi-autos,of many different brands. Some say it is designed-in frame flex. I say BULL SQUAT. None of the shooters at my thursday night shoot have slides dropping 'unintenionally' when doing fast mag changes ,or slow ones. what do you think gang,? I think this is a dangerous design flaw,not something that should happen by its' self . I know my 1911 does not ever do that,yet some of the folks their say their 1911's do it all the time. what say you,am I out of the loop on pistol operation ?
