I had bought a 9MM Sigma in 1998 and shot it twice,but not in the last 14 years.My son borrowed it last year and said it was having some issues with jamming.Fast forward to this year when I took my concealed carry class and was considering a few newer semiautomatics.After reading about the Sigma problems on this forum,I called S&W and told them of the issues with the gun and they emailed me a mailing label.They called the following week and said that my gun was unrepairable and offered me a free replacement.I chose the Shield 9MM with the safety and just paid the fees to the gun shop.Since then I have bought a Bodyguard 380 and a Ruger LCP.It has been 95 days since I applied for my CC card in Illinois and I am still under review.
