Best firing pin for 610-3 (lots of light strikes)

[3Gunnah]

I have a 610-3 3 7/8" barrel. It is the only IL/MIM Smith I own. I will be moving up to a 610 no dash this summer if all goes well........But in the meantime who makes a good replacement firing pin. This gun will not shoot a cylinder of ammo with out a missfire. I have tried all types of primers. I have tried high seated primers, deep seated primers. I even broke out the factory ammo for a test run. I only bought this gun because the deal was to good to pass up and I HAD TO HAVE A 610. The guy I bought it from only fired 200 rds and he had no issues ( I know because I was the RO at the match he shot with it). Please help with an aftermarket pin to tide me over. Thanks

Make sure the strain screw is all the way tight. Also pull it out to make sure someone did not file/shorten it. If it is correct then the extended firing pin brownells sells would work fine.

I have checked and the gun is as new. Thanks
