Ok, I did a search and did not find sufficient information to answer my question, so here goes. How do the polymer pistols hold up compared to steel frame (1911) pistols? Already have a SA mil-spec, but have kind of had my eye on a SW99 for my next addition. I just don't want to spend the money on the SW99 if it's life-span is going to be noticeably shorter than a 1911. If so, I'll just go with another 1911. Oh, and assume generic ball ammo being used 99% of the time. And--.45 of course!
