Sounds like you got a good deal. It might not be a bad idea to have a smith check it over for any bushing or springs that need replacing. Also, what barrel length did you get?

I had a M13 4" for a while (same basic gun but blued). It worked decent but I never did find a set of K frame grips that felt real good to me, and I've had a couple of K frames to experiment with. It funny, the OEM grips on my Taurus M65 work just fine.

That depends on how you feel about the whole full power using lighter bullet thing. There is a flat spot on the forcing cone that sometimes cracks with the 125gr loads. I haven't heard of any issues with the heavier bullets. Here's some articles with more information:

Now, I'd shoot what I wanted to and not worry about it, especailly with what you paid for it. But you may chose differently.
