Fits 3.6” barrel and slide by AH, Verified Owner, August 10, 2025
Not much to say. This fit my 3.6” barrel and slide build. Sig didn’t have this item on their own website so I ended up finding it here. Way to go Optics Planet!

completely wrong recoil spring by Derrick, Verified Owner, February 2, 2023
Completely wrong recoil spring, and what they sent isn’t even what is pictured. I compared it to my sig compact and it’s the same size but is still not even compatible with that. I’m sending it back in hopes they send me the correct one.

Recoil spring by DARKPREACHER, Verified Owner, November 12, 2024
I'm sure it works fine but apparently I bought the wrong spring for my sig build when what I needed was the AXG LEGION SPRING/ROD...Oh well lol

its a review by Lou, Verified Owner, May 24, 2024
Recently purchased this item and it was a perfect fit for my p320 build. Have yet to shoot the newly built pistol but I’m more than positive it will work great.
