My '92 SIG P220 with a stamped slide has a black 15lb recoil spring that is multi-strand and about 1/2" shorter than the new 20lb green recoil spring. I bought a supposedly like NIB P220 recently with a G354 serial # (2004) and a stamped slide but it has a green spring. My understanding is that the 20lb springs were introduced for the milled stainless slides due to the extra weight. Did SIG issue green springs for the folded steel slides? I ask because I'm wondering if the green spring is the one that originally came with the pistol or whether the seller changed the spring. There's some odd wear on top of the raised "lugs" on the frame near the muzzle. My '92 P220 with tens of thousands of rounds through it has considerably less wear on those lugs. This "new" pistol supposedly only had 16 rounds fired through it. The condition of the barrel and mag well are consistent with very low use but the wear on the frame looks like it came from someone racking the slide about 10,000 times!!!
Thanks.
