newmexicocoonass Posted August 17, 2019 Report Share Posted August 17, 2019 Getting ready to SBR my Kahr SA. Going from stock 16.5 to 10 or 10.5. Question: Are all Thompson barrel threads the same? Will a USGI 10.5 M1/A1 barrel fit on a Kahr SA? Will a 1928? Second question, does anyone know the weight difference between a M1 plane 10.5 and a 1928 finned ? Thanks !!
