Gentlefolk, I let my enthusiasm for Sigs possibly get the better of me. My LGS had a used P220, SN:G 167 xxx Sales guy guesses maybe late 90s, and it has had a number of rounds shot thru it - obvious wear on the top of the slide, but it appears to me to be tight and solid, so I bought it for $565. I took it to the range right after I bought it to put some range FMJ thru it. The first two mags of five rounds each ( there is just one mag) ran fine. The next five rounds of five rounds all had the final round fail to feed. The nose of the round jammed on the edge of the ramp, the nose was not tilted up to go i to the ramp. The round was still perfectly horizontal the nose not tilted up. If I rack the slide back and let it go forward - let fly- the final round chambers. I talked to the sales guy and he pointed out the significant crud buildup on the ramp, barrel and basically everywhere. He suggested cleaning all the crud out and trying again. I have just completed the cleanup, but when the slide is manually released, but the battery force is slowed by my hand...that is when I ease the slide forward, all rounds feed correctly save for the last round. I have not yet fired the P220 since cleaning. So, my questions: 1: did I screw myself by getting this piece at this price, and 2: is the fail to feed a mag issue, recoil spring issue, both, something else? Honest assessments appreciated. Thx!
