I purchased a S&W Victory through Davidsons Gun Genie and had it shipped to a local gun shop. I tried to field strip it and found the barrel locking screw was impossible to remove. I bent the factory Allen and a Sears T handle wrench and the screw didn't budge. It appears my efforts stripped the head of the screw. I returned the pistol to the gun shop for return to Davidsons in accordance with their lifetime warranty. I decided to buy a S&W Victory for ease of take down, I guess I should have waited for the new Ruger Mark IV.
