During Saturday's match I had 4 instances of FTF across three of the four stages I shot. I haven't had time to dig into this further, but may get some time in the next few days.

azrik Posted July 25, 2017 Share Posted July 25, 2017 I had a similar issue with my MP9 2.0 where the round was hanging and seemed to chamber in a "2 step" motion. I found that the bottom corner of the extractor hook was digging into the extractor groove of the case. I took a 1911 trigger channel stone and very slightly rounded the corner that contacted the case on it's way up the breechface and no more 2 step hesitation. You might want to look at that corner to see how sharp it is and if it's stopping the round before it can slide under the extractor. Link to comment Share on other sites More sharing options...
