Mine was a Sig P320 Compact w/ the manual safety (back when they were first added to the Massachusetts"roster" and before I knew about frame transfers)... I sold it after I bought my HK VP9K, and sold the VP9K for a Glock 45 MOS.
Now, my first Smith?: A current "dash"/ production S&W Model 617 (won it in a raffle at my LGS). Ended up having so many QC issues with it I traded it for a blued, 2.5" S&W Model 19-5. That started me down a rabbit hole of pre-Lock K-Frames. Recently picked up a Model 67 no-dash to compliment it!
