Thanks for bringing this back up.
I planned to reply and figured I'd have to go digging to find the thread. But you did the work for me.
I finally got mine to the range last week.
In actual use, the trigger didn't feel as bad as casual manipulation.
After 10-15 rounds, it smoothed out a bit and felt notably better.
By the end of the session, it seemed fine. Still heavier than desired, but nothing like it was right out of the box. I can live with what it is now.
However, it won't cycled 115 gr ammo at all, is 50/50 with standard velocity 120-125 gr ammo, and is only reliably cycling with 124 +P or stout 147 gr loads (not necessarily +P).
So, that's something I need to figure out.
The recoil spring is ridiculously heavy, though. Heaviest spring in any full size 9mm that I've handled. I might need to swap that out or see about some redneck solutions.
The above being said, I didn't get to shoot the pistol any more after about 10 minutes. My 12 year old son stole it and wouldn't give it back. He shot only 115 gr ammo, so that he didn't have to chase the brass.
