Extended grip safety NOT needing frame alteration

Some time ago I purchased an extended grip safety from Gil Hebard that did not require frame alteration and am looking for several more.  Anyone have one for sale, know where I could get one or a similar product.  It worked very well for bullseye.  Thanks, Dick

try brownells or midway usa

Wilson makes a drop-in version. Requires no frame alteration but the pad may need to be fitted to your individual trigger.

Drop in depends on the cut of the frame, there are two or three different ones, you must first determine which you have.
