[QUOTE=GypsmJim;140082116]I've owned the gun for 10 years or more and have not had a problem before. When I bought it the PO said it had a "trigger job", and it's evident by its very light trigger pull. However, its also the most accurate S&W I own.

Recently started having light strikes and no fire. Using handloads. Naturally, the first thing I did was check primer seating and that was OK. If I try hitting it a second time, maybe it will fire maybe not. Yesterday it took 4 tries with one round. If it doesn't fire on the second try, its still a light strike. When it finally does fire, the primer strike is normal.

I can go thru several cylinder reloads and it won't happen. Then, it starts again.

The same ammo is 100% OK in another .357 revolver.

Any suggestions appreciated...[/QUOTE
Sounds to me the mainspring is on the verge of not being reliable would be my first guess.
