Sure! It's a Early 4013 TSW (non-rail) in 40cal. It was made in the first 3 years. After that they put rails on the frame. It was NOS when I bought it and now has about 250 rnds through it. Nice weapon. The other pics in the album are of a 6906 9mm. At the top of the semi-auto forum page there is a "sticky" that explains what the numbers mean and what calibers etc. I was a revolver only Smith guy and like you didn't know much about them. My first was the 6909 in 9mm. I Love the 3rd generation Smiths. Too bad they quit making them...Bob
