Heres a couple that suck...

Smith and Wesson.....I have about a 1940s nickle Snub nose JFrame .32 long...might be an I frame not sure and don't care.

The main pin that the hammer rides on in the frame broke I called S&W anout getting it repaired....everything was going good until I gave him the serial number then he advised me that they did not work on guns built before 1960.

A few years back had issues with an AR scope....sent it in to be repaired they charged me and made me sign a waiver stating that I would not bad mouth them on the internet or they would sue me.

I paid them and signed the waiver so I cant tell you the name of the mayor company....looking back I should have thrown the scope in the trash and trashed them.
