    I bought one as a project. They are known to fail to feed & fail to extract and jam.
    My first thought is to try different springs. Anyone have any suggestions or expierence with the AMT backup?

    My mother has carried one for years. Never had a problem with it as far as I know.

    I doubt the springs are the problem. They seldom are.

    AMT had a lot of problems with galling. They were the first to use stainless steel in mass produced self loading pistols. Try Rig Lube +P. Specially made for stainless steel.

    I had the same cleaning problems too. Because the gun is so difficult to brake down. I cleaned it with a can of Blake cleaner. Once it dryed I then lubed it with spray oil then buffed. Been fireing flausly since

    They are a major pain to brake down.
