Very very Nice S&W M39-2 and 9mm Sig P220!
Congratulations!
My very first handgun was an S&W M39 basic (no dash). I later traded it for a S&W M19 .357 Magnum Revolver, which later got traded for a WWII Walther P38, which I still have. I have often thought of picking up one of the M39's successors such as the S&W 5906, but have never found a good deal on one.
I also had a Sig P220A in .45 ACP. While it was a very good .45, it always seemed to lose out to my .45 Tanfoglio Witness Pistols and was sold off along with a few other firearms to fund my L1A1 FN FAL project. I also had an excellent 9mm Sig P226 which was an excellent handgun.
