It's a 32 Degrees style grip-frame. Something from their Enforcer Era. It's the little things too. It may just me me, but It's the same quick disassemble pin, and the same rear adjuster you see on their markers. One other way to tell is if the internal seal on the pin is molded to it. Another sign it might be a 32 Degrees marker.
This makes me feel really old actually to have pulled the Enforcer card.
