I have a P220 compact. Not the carry. I had a P220 Elite Dark that was fantastic. But I like the compact. Got it used. Sent it to Sig for their refurb program. $140, full inspection, new springs where indicated, Sig nights installed. While it was there, I had them do the SRT trigger and a full trigger job as well. Now it's a fantastic pistol and allowed me to confidently sell my Dark Elite. I used the funds to get the AR 15 Sport. Totally happy with my decision.
When you get the new parts in your Sig, it will be a gun you'll never sell. When it's done, tell me what you think.
