About 3 weeks ago the firing pin to my original S&W model 59 broke. You tube did not have anything for the original so I checked with Midway to see if they had a new firing pin for it. They did and they suggested a firing pin spring also. I ordered both 7.95 for both. I got it yesterday and I had no idea how to replace it so I called Midway. They put me in touch with their gunsmith who walked me through from start to finish. Fifteen minutes later the gun was put back together.
One thing he said was to stay away from Federal primers as they have very tough cups. He said that some of the striker fired pistols were having trouble so they no longer recommend them for older pistols or striker fired pistols.
That is one great company.
