Need advice on making a few cuts to a leather holster. I searched old threads but didn't see anything. Have an IWB Leather holster that partially covers and can activate ambi magazine release on pants side (outside) of holster. I need to cut just a little of the holster away from the magazine release so i don't have a magazine drop out on me. Before i started attempting to cut, thought i'd tap into expertise on the forum to see if anyone has suggestions for best tools to do this. I have to cut approx 1/8 or more around mag release and would like to know which tool(s) would work best for this since i've never worked on a piece of leather like this. It is double leather wall since it is place where holster portion joins with belt retention clip portion so is fairly thick that needs cutting. Was thinking even a drill bit around this size but thought i'd get the advice of experts before i screwed up a holster. Any suggestions are welcome...
