Blacked o s, when you tire of sending your 41 back and forth to S&W for repairs. David Sams or KC's Kustom Creations or several other competent gunsmiths known to others on this site can get it running like the racehorse it is supposed to be. S&W barely can assemble the line it sells much less service the troubled ones. Waste of time to send for free service in my experience. Sorry you got one of the few that does not work.
