I was asked to respring an ailing SMK 19,.....Well I could not believe the response from SMK when asked for a spring.....
Sorry our gunsmith is on holiday and we only have export springs which produce 22ftlb!!.....
Yeah right.....just send it please.....
Well I wasn't going to get a 22ftlb spring now was I.....no someone had hacked it for me.....badly......after redressing the last coil and flattening off.....I fitted it into the 19 with a little grease.....almost no preload, it was just a gentle push in and replace the pin.....
Time for the chrono and TBH I wasn't expecting a lot but was very plesently surprised with a nice 11.2 and smooth cycle.....am I underrating these things....can they do 20ftlb?? Any one have more experience with these??
