S&W Mdl 39 was also the first DA semi auto 9mm pistol adopted by a North American Police Dept, Illinois State Police in 1967. It played an important role in later developpements in Police Depts arsenals as most corps (if not all) are using pistols these days...
Had a few 39s over the years....Used to be a favorite daily piece 20 years ago as it's light, slick, accurate, compact and carries well in an IWB. With good ammo it's 8 + 1 capacity is all you need in a defensive pistol. Grip shape, specifically that round backstrap, is one of the most comfortable I've seen...As for looks, a second generation stainless Mdl 639 with the original walnut grips is quite nice...
Thumbs up to Barry out west, I can attest he does some great work at fair prices.
