I bought this pistol in the beginning of December from a local gun store. It was used and had been bought new by one of the employees of the gun store I bought it at. I was immaculate when I bought it. The previous owner had only put about 4 or 5 hundred rounds through it. I have put about 600 rounds through it myself. About 225 rounds have been .357 SIG (I bought a factory sig barrel to convert it from .40 to .357). I fired 120 rounds today. When I got home to clean it I noticed the takedown lever is sheared off and missing. The gun still functions fine, I just can't take it apart to clean it. I am not the original owner, so I doubt SIG will warranty the part, but I obviously need to replace it. What do you think of these pics?
