Hello to all...I have a chance to get back my old 3914 from the friend I loaned it to almost 10 years ago if I want it back. I am really a revolver guy but have a fondness for this pistol. However, I can't remember when I first bought it, maybe someone can help. SN is TEC 46XX. I was the original buyer and wonder if it came out after Smith introduced the lifetime warranty. I was in the army and it was somewhere around 90- to maybe 94.
