Hi all,
So this goes back some time but I just began thinking about it again. Some time back I bought an M&P 9 FS and an M&P 9 C. Both have manufacture dates of March of 2013. Not long after I purchased two APEX DCAEKs from the same vendor online. The install for the Compact went fine. On the Full Size I noticed something odd. The Compact ended up with a trigger pull of ~ 6 lbs. 2 oz. The Full Size ended up ~ 7 lbs. 5 oz. That's a pretty big difference when they should be roughly the same. Later on I did another DCAEK install on another Compact and ended up at ~ 6 lbs. 2 oz. This got me thinking about the Full Size.
I swapped the APEX trigger return spring back for the stock. The trigger pull went down to ~ 5 lbs. 5 oz. This seems mighty odd to me. Is it possible for the APEX trigger return spring to be out of spec? I did a complete frame disassembly and reassembly and got the same results. In addition, the pull on the Compact is very smooth all the way to the breaking point. For the Full Size it feels like something is rubbing. Both pistols have the APEX USB (striker block). I'm somewhat concerned something might be out of spec on the Full Size and that's what's causing the differences I am seeing.
Any thoughts?
