Does anyone have the steps or options for converting my semi Kahr TM1 to accept original GI 20rd mags. My goal to to do the form 1 for the SBR and also add the 10.5" barrel and fore grip, but this is the first and easiest modification to make this TM1 look like a WW2 era GI M1A1. More questions to follow on barrel removal, stock replacement, etc as I'd like to eventually have a worn look GI M1A1 Any help or advice appreciated. John
