For the couple folks above considering a 226 for their first - just do it! Great all around platform, very accurate, simple and reliable. You could own this as your only pistol and never go wrong.
Warning - Sigs are like a sickness. You won't be able to stop the infection once you start.
You'll soon find yourself with, in addition to a 226 TT, an X-5, 220 Carry Elite ST, 239, 239SASII, 220ST. Just to keep the S&W 642 company, along with the Colt 6920, FN Herstal 12ga., etc., etc......
Happy shooting. Thank God ammo is available and (somewhat) reasonable again!!!
