Optic cut , new trigger design , with or without thumb safety , 15 rounds , 4 and 4.6 inch models
Frame and slide are from the M&P45/45c, so we're stuck with those barrel lenghts.Would have preferred a 5" barrel. But I'll still buy one.
If the price of that kit is more than about $50, you're probably better off buying an APEX trigger. APEX costs three times that, but it's much (MUCH) better.... it will be possible at some point to get your hands on the new trigger and it should work in the 2.0 45s.
