This is my duty (California LE) firearm and my daily load out (external vest carrier + Sam brown belt). Standard 8+1 in my firearm and x7 spare 10rd magazines. All are Sig Sauer branded and marked "made in Italy". It came stock with the SRT.
Prior to this pistol, I carried a P226 .40 for over 10 years. I have owned this pistol for nearly two years, and put countless (several, several hundred... maybe over a thousand) rounds through it.
When I first bought the P220, I had a problem with the pistol getting stuck out of battery. If I pushed slightly on the slide, just barely pushing it out of battery, it would stick there until I racked the slide.
I sent the P220 back to Sig for repair, and while it was there I had them perform their "action enhancement". The pistol came back and the problem was gone.
Since then I have fed my P220 a VERY healthy diet of Winchester Ranger 230gr T-series (department issued) ammo.
Initially I believed my P220 just required a lengthy "break in" period. I don't know why I felt this was the case, as my old P226 shot fine right out of the box. The problem is, ever since I bought this pistol, no matter which magazine I use, I get the same jam. Most often I see the jam occur within the first 3 to 5 rounds, when using the extended magazines. This has actually occurred more than once per mag. (Very rarely, the slide will fail to strip a round from the magazine, and will leave me with an empty chamber)
Here's a view of what the jam looks like. I don't know how well you can see, but the jam appears to be inside the mag. It's as if the cartridge tips forward before it loads, gets stuck, and prevents the slide from pushing the round into battery.
My question is, has anyone else run into this problem? Are there any suggestions? I plan on putting a call into Sig ASAP about this. I fear if it can't be resolved, this pistol may get retired early. Perhaps another .45 is in my future???
