Doc Sunrise,
I have a question for you. Does your USFA Lightning bolt lock when the hammer is cocked? By that I mean that with the hammer cocked, you cannot pull the slide to the rear. I know that you may very well be able to hold the trigger and slam fire the thing, but in the normal course of events, my Uberti does not lock and that can lead to problems of the cartridge not being fully chambered when the hammer falls, it then goes kerthunk and I have to cock the hammer and go again. That is a royal pain, the work around is to really slam the bolt home when you cycle the action.
