Sig P220 Locking Insert New

56.00

Picture shows a used 229 but these are new production 220 four dot locking inserts. There is some confusion about the four dot and five dot locking inserts, all my kits had four dot inserts for milled slides. The feedback I have been getting from people that have completed their builds is the four dot functions flawlessly.

Apparently the 20# recoil spring is what Sig is recommending for the 220, changed every 3000 rounds.
