Is it OK to dry fire the 340 pd scandium revolver without using snap caps ?

Welcome to the Forum. Always great to have new members. I have dry fired my scandium guns without snap caps; revolvers are made to be so dry-fired. Since I have these caps, I prefer to use them with all my .38/.357 guns.

FWIW: I occasionally dry fire my centennial j-frames without them, but if doing so extensively, consider the following commentary from renowned author, instructor and revolver gunsmith Grant Cunningham...

"If you pick one of the lightweight Centennial models, there is one specific concern: the hammer comes to rest below the firing pin, as opposed to above like the other models. The metal in that area can be very slightly swaged into the firing pin channel by the hammer; I've seen a few where firing pin travel has consequently been compromised, leading to possible ignition failures. In fact, there is one on my bench this week with the beginning of the problem. This isn't an issue from firing live rounds, but from dry firing without spring-loaded snap caps. If you elect one of the 642/442 models, do not dry fire without snap caps."


Does this still occur with the scandium frame guns?

"Probably, though to a slightly lesser extent due to the tougher material."

Mister X: Thanks for posting. Cunningham knows his stuff
