So on my RIA ultra fs 10mm the hammer broke in half after about 1000 rounds , I installed a flat bottom firing pin stop and a Wilson 22 lb recoil spring at around 4 - 500 round count. So I send it in ( with factory fps and recoil spring reinstalled ) and the factory smith changed a bunch of parts and installed a 22 lb hammer spring (factory stock is 25 lbs ) . Not sure I like that this was done, I installed the heavier recoil spring a flat bottom fps to keep the brass from flying 30 ft . So what effect will a lower hammer spring have ? I’ve been doing some searching on this but would like to know what your thoughts on this are ?
And please let’s not turn this into mim vs forged , after this happened I googled 1911 broken hammers and found forged one’s have broken also .
