I was in the same position you are now. I got to try a SIG P210 years ago and wanted to get one, but they were always not available or too expensive. I happened to find exactly what I was looking for a couple of years ago: a 210-6. It has adjustable sights and plastic grips. I replaced the plastic grips with beautiful Nill grips and put on a “grip safety” extension to prevent hammer bite. I also found some mags from a German gun store on line and got some new mags. The new mags worked, but didn’t lock the slide back. Numrich had the proper followers so now I have 8 good mags.
The thing is a really sweet auto. Accurate with anything I feed it. So far, it has cycled anything I put in as well. Good luck in finding one.
