Getting familiar with my new Trade Gun, I notice that I cant lower the hammer to half cock without lowering all the way and then bringing it back. After some searching I have found out about the fly. What purpose does it serve? I read a few references to removing the fly but no definite answer to whether it actually helps. Is there a way to modify and improve the function? I dont really want to resort to upgrading to an L&R REP lock, although that may be a possibility. Seems to me that the fly has no purpose except to agitate me, or would the sear hit the half cock notch when firing if it wasnt there?
