Took this guy out for the first time today with mixed results. about two hundred rounds. Not problems with function as far as feeding and extraction. Very accurate. Now the fun part. When I bought it, it was filthy. Trigger pull was fairly heavy, felt like standard hi power trigger. After about 2 hours of scrubbing with a toothbrush and breakfree it was clean. At the range trigger felt very light. Almost to light. Noticed the pull was getting lighter. After about 180 rounds started to notice there was no wall in the trigger pull. Slowed down my shooting. Hammer started falling when the safety was disengaged. That's when I stopped shooting. The RO let me use the trigger scale to measure the pull. Came in at just over a pound average for 5 pulls. Yes, it still has the mag safety. If anyone has any thoughts one this I'm willing to listen. As it stands now, in my opinion it's a dangerous trigger. I think I'll be sending this one of to mk3 firearms for a makeover.
