Hinge/back tension release with safety, in quicksilver brass with flex fingers.  Great for new hinge shooters nervous of punching themselves in the face.

Almost new with very little use, it's a lovely thing but not for me.  Comes complete with thumb peg, three and four finger flex fingers, lanyard and hex keys as shown.  It only comes in one size, which matches my other medium Truballs. 

Currently around £230 new for the three finger,  and the four finger flex fingers sell separately for around £25.

Can post within the UK at cost.
