I have, sitting in a drawer, a Galco Ankle Glove holster that I used to carry a Glock 26 in. I sold the 26 long ago and the holster has sat in a drawer ever since. I am considering picking up the new Glock 42 as a deep conceal piece and thought it would be a great time to dust off the ankle holster. The 42 is a fair amount slimmer than the 26 was so can anyone recommend a good way to modify the leather of this holster to fit the new gun?
