It could be the handgun but it could be the ammo that was the problem too . One thing you may be able to bank on is ruger will fix the issue . I had more problems with rugers than any7 other brand BUT they stand behind there products .

I have had one primer back out of a factory 357mag load since 1976 and it locked up my DW revolver . Had to shim the front of the cylinder to remove any gap then work a heavier greased shim in behind the primer enough to force some slack between the primer and breach face to open it by hand . That was one of the big ammo company loads . .
