I picked up a m18 fcu (wanted thumb safety) for very cheap.. Now I know I'll probably end up getting a wilson grip module down the road but can anyone educate me on:
-triggers, which do people prefer and do they work with the safety
- Tell me about the slides: 3.6, 3.9, and 4.7
-barrels? Just go with factory?
Factory optic cuts look like a nightmare to sort out, a lot of the x series guns now have the plate infront of the rear sight which is a plus.
