I don't know if price of the gun is a big factor or not. In the Sig, I would recommend the P250. It was not a great seller for Sig Sauer so you can probably find them at a reasonable price. I have one in .45 and I have another that has two complete "uppers", one in 9mm and one in .40 S&W. One of the neat thing about the P250 is that you can change out the slides assemblies and the polymer grip assemblies to find one that will fit just about any body. Go over to the Sig website and see what I am talking about
