So for the longest time I had been running a knock off, “gun show special” ACOG on my SBR. Well I finally decided to pull the trigger and get a real ACOG, and wow. As the title says, I get it now, the difference in price, I mean. The glass is so clear, I wouldn’t know I was looking through an optic if it weren’t for the reticle. I don’t think I would want to shell out the money again, but it is one of the best optics I’ve ever used.

So as the title says, I absolutely love this XRay3 slide assembly. My P320 was a first generation, “Carry” model, or in another word, “Boring”. I ordered a new Carry-X frame, Sig’s Magwell, and the XRay3 slide assembly and did a major upgrade. It looks so good now, and shoots even better. Barely any recoil, the sights you can pick up immediately, the only thing I don’t like about it, and this is 100% my fault, is that I didn’t think about the OE Sig holster that came with my P320 not working anymore.

The issue I mentioned was that it would not rechamber a round after shooting on. Or I guess to be more accurate, it failed to eject the spent casing. Part of the time it would eject about 25% of the way, others 50%. I took it back home, disassembled and reassembled it, went back to the range last night, and still had the same issue. I put my original slide assembly back on the new frame (to see if it was a frame or FCU problem) and it ran perfectly.

On a whim, I put the spring from my original slide assembly into the new XRay3 slide assembly, and Viola, the problem was solved. I ran a couple hundred rounds through it last night, a few mags shooting it as fast as I could trying to get it to fail, and ran like a top. I’m guessing the spring in this kit is a little lighter to accommodate the compensator.

So in a nutshell, I love this kit, and would highly recommend it. Just use your original spring.
