Swapped out the stock muffler for an undaunted cover. Haven’t cut with it, but did start it to hear it. Thing sounds like a dirt bike from my youth with the throttle wide open!
So after close to 4 weeks with HK they found nothing wrong. I took it to the range yesterday and but around 80 rounds through it and had 0 malfunctions. Trigger didn’t even give a whisper of a malfunction. Who knows why the trigger locked up the first range time. I am planning to take it back in the next few days and give it another work out.
First mag (12rd), gun ran flawless. Every mag after that it would develop a dead/ stuck trigger. I would depress the safety shoe and pull the trigger and it would travel about 1/3 to half way and stop. It was like it hit a wall. Tried no mag, other mag and nothing. Time for it to go to HK. Feels the same as if you don’t cock the gun and try to pull the trigger.
Feels very good in the hand, though I need to figure out something for the grip, the sides are as slick as a 70’s pickup line. Front and back are decently stippled, not the sides. I also stream light tr7 is too long to mount. 1913 lug sits just in front of the pic rail.
