Obvious Posted March 13, 2021 Share Posted March 13, 2021 I recently got a RIA 1911 I plan on running in limited and I've been looking at the MBX mags. Why are they 141.25mm long? I thought the limit was 140mm? I'm assuming I could sand the basepad down a little but I don't see why they're just not 140mm. Link to comment Share on other sites More sharing options...
RJH Posted March 13, 2021 Share Posted March 13, 2021 The 141.25 is legal in uspsa. 140 is ipsc. I *think* they made the 141.25 rule so if you were shooting 140s you had a little buffer for tolerance stacking. But gamers gonna game Link to comment Share on other sites More sharing options...
BoyGlock Posted March 13, 2021 Share Posted March 13, 2021 No 140 in ipsc std div. Gun must fit the box w/ empty mag inserted. Link to comment Share on other sites More sharing options...
71Commander Posted March 20, 2021 Share Posted March 20, 2021 If you want to always be on the safe side you can go to EGW and buy a mag gauge. Link to comment Share on other sites More sharing options...
