Weak ignition was a cause of hangfires and misfires (and cold) in my S&W 586. I was using AA#9, the weather was cold, and the mainspring was old.

Replaced the mainspring, and everything worked fine in slightly warmer weather.

Is your mainspring tension screw backing out?

Maybe your primers are too deep or not properly seated?
