Yup, trigger kinda cheapo. Can be fixed, I've heard, via tuning, or upgrading to an all metal one from a 390 or 303. I'd guess that a conversion to release makes for one sweet trapgun. Consider closing bolt at an opportune time so targets not released, or close it gently and not letting bolt slam home.
These are, again, IMO, the "small block Chevy" of trapguns in today's world. Little felt recoil, strong quality for the money, nice looking, fun to shoot.
