Absolute junk - Rival Arms Slide Completion Kit for SIG Sauer

Bought this thinking it be nice in my killer instinct flux build because of the pvd finish. Firing pin is silver just like the factory sig one. Not to mention, I think all the parts are exactly the same as what comes in the factory sig sauer kit. My package came with extra parts that for the life of me I can’t figure out what they’d be used for. Definitely not for use in an sig p320 slide!!! And to top it off it didn’t have the extractor spring in the package… friggin garbage!!! Not to mention that is lit took multiple trips across the us with the usps advantage ground shipping. So rather then waiting for optics planet to solve this. I jumped in the car and drove to local sig and bought their completion kit for $95. Just buy the sig kit. Fits perfect and has all required parts in it!!!
