Which main spring would it be possible to use with both 9mm and 7.65 and which main spring would not be advised to use with both. I have both 9mm barrel receiver and 7.65 barrel receiver but only the 7.65 bolt assembly/lower. All parts seem to work together but I have not done any shooting just working slide and dry firing. Everything seem to work smoothly...Am thinking of obtaining another bolt/toggle assembly?..........
