One of my friends just bought a S&W model 40 F. As far as I can tell,it is a Sigma series but I`m having trouble finding information about this gun.Are any of you familiar with it?
Info on the SW 40 series. The F was the original version, pre-1999, with longer barrel:

Action: Single Action *
Caliber: 9x19mm Luger/Para in Sigma 9; .40S&W in Sigma 40; 9x17mm (.380ACP) in Sigma 380
Overall Length: 184 mm
Barrel Length: 114 mm (4.5in) in pre-1999 Sigmas; 101.6 mm (4 in) in current versions
Weight: ca. 690 g empty
Capacity: 16 rounds (9 mm); 15 rounds (.40SW)
The Sigma series of pistols was introduced in 1994 by its first model, Sigma 40F in .40SW, following with 9x19mm version. Sigma pistols bear so much similirality to Glocks, that the lawsuit was rised against the S&W, so Smith & Wesson finally paid undisclosed sum (some millions of $$$) to Glock for violation of their patents, and then S&W received the rights to continue the production of Sigma line.

technically, Sigma pistols are recoil operated, locked breech semi-auto pistols, built on modified Browning-style linkless locking principle. All Sigmas feature Glock-type single action-type trigger with automatical half-**** and manual striker cocking during trigger pull. Sigma pistols had no external (manual) safeties. Gun frame is made from polymer, the slide and the barrel can be manufactured from the stainless steel or from the carbon steel (in so called "Value" models).

In 1999 S&W improved the Sigma series. Main change was shortening the barrel and the slide by .5 inch (12.7 mm). Other improvements included more comfortable grip checkering, slightly enlarged ejection port and addition of the acessory rail at the front of the frame (under the barrel).

I was watching this as well. It appears you've finally struck on something that no one here really knows anything about. The only experience I ever had was one my brother in law had bought. I didn't care much for it so didn't do a whole lot with it. He parted with it and ended up with a CW 9 with no direction from me. I guess he liked my K40 and got a deal on the CW so another happy ending.
I guess I had two experiences now that I ponder it. My future son in law was at a shop not too far away, thankfully my daughter was with him. She texted me and said he was buying a gun, I asked what kind, she said S&W auto. I asked which one, she didn't know. Fearing the worst I called even though with my hearing it's a pain, I asked to speak with whatever salesman was selling a gun to a bald headed young guy. They put him on the phone, I asked what Smith he was selling. the guy was put out but asked why, told him if it was a Sigma it was gonna earn him an arse whooping from an old man in a wheelchair. Turns out it was and M&P 9. Nice gun, should have been a 45 but oh well. I should send that salesman some flowers.
