I currently own a springfield xd40, and a refurbished .357 ruger blackhawk, before I found the sig p239. Shot over 2,000 rounds through it with excellent grouping even @ 20 yards. The only jams Ive encountered are with P.O.S. PMC ammo purchased from longs. Now I buy the Winchester FMJ 100 pack, shot another 500-1000 and have not seen a single jam. The action on the gun makes my Springfield look like a cheap toy.
