I had the exact same model which I acquired for use as a 'Club Gun'. That gun had thousands of rounds through it during my ownership and NEVER missed a beat, no new springs, firing pins or anything else. The only thing that I did to it was to strip the varnish finish and oil it, due to people hitting the back of the 'Monte Carlo' stock comb on the bottom back board of the gun rack (TAKE NOTE !). Lovely gun and I wish I still had it..
