Just recently, the Sigma SW9VE was brought on line as an Allied Forces Model SW9VE, with the Afghanistan National Army, National Police and the Border Patrol placing initial and follow-up orders for more than 22,000 of the 9mm-chambered pistols.
It's not a refresh, it's a midline gun between the entry-level Stigma and the high-end M&P. Should compete directly with used Glockrenades.
The Sigma is supposedly S&W's best selling semi-auto since it was introduced (not sure if that's actually true but is the rumor). Most people who buy a defensive handgun just want it to go bang each time the trigger is pulled, and the Sigma certainly does that - it's a reliable enough design (assuming they can pull the trigger)
