Took it to the range today.
The trigger pull sucked. It seriously has like a 50 lb. trigger pull. Now I'm a big guy, and I couldn't always get it to fire. I couldn't generate enough force with the pad of my finger to get it to discharge, I instead had to put the trigger at the joint and squeeze like hell, and that didn't always work. My shots at 5 yards were consistently 1 foot high.
I got it home and disassembled the gun. I found the trigger return spring to be ridiculously stiff. I couldn't compress it at all between my finger. I found that an AR-15 trigger return spring was the same diameter and MUCH lighter. I think I have the trigger pull down to 20 lbs. I think I'd need a lighter hammer spring to get it lighter. I don't want it too light, as it has no trigger guard, but maybe a few pounds lighter would be nice.
