WOW I am glad that I bought my first sigma in 1995, second in 1997 the other dozen have been since then, BEFORE I knew there was a problem. 40 cal and 357 sig all of them. Rounds unknown,dry fire unknown, the first 2 have been my carry gun (s) since they were broke in. I did have to replace a striker spring (light hits ) at about 5000 rds, Lucky- no just well made guns. If you check the lounge I put a post up for SW service on 2/28/2012, after I managed to shove the guide rod through the front of the slide,lock up the gun, repaired & returned in 10 days including the weekend. They paid shipping both ways. In 1996 I dealt with S&W for 4 MO over my new 629 that I could not hit a target board 3 ft X 4 ft @25 yds with my target loads, worked up in my 29. They move the sights, replaced BBl, cylinder, etc, till they finally shecked the frame that was drilled off center. So it does not matter S&W, kimber Gold match II ( rear sights fell off 25 rds, repaired, fell off @ 30 rds of factory hardball, colt, glock,ruger, myself or someone has gotten one that has broken for no good reason. Call Smith, they will send a mailer, get it repaired and shoot,shoot,shoot, most of all enjoy!! Be Safe,
