I don't know but it may be time for another gun if self defense is its purpose? One that's new, newer or an older one that's still in production like a 1911. I have a bunch of older S&W semi auto's that were made in the 1980's when most police agencies started switching over to semi auto's. Magazines and some parts are nearly impossible to find. In spite of the fact that tens of thousands of these guns were probably made?Not that I know of. I have two, I just wanted to try to find another one. It's very accurate, but these days I'm afraid I can't find parts. I have a Remington mod 51 .380 that I don't shoot anymore for the same reason. I got it in1969, but I think it was made around 1918.
