I had a Sterling Arms .25 pistol at one time. Jam-o-matic piece of junk, I would get 4 or 5 stovepipes out of a 6 round mag....not good. It doesn't surprise me that they're out of business.
My best advice is to get rid of it and look for something better.
I don't usually bash any particular brand of gun ( except Glock
), and while the Sterlings appear to be well made, I was never able to get mine to work right.
I sold it to a friend of mine for 30 bucks and I was happy... Until he traded it straight up for a S&W model 36
