Completion Slide Parts Kit for Sig Sauer P320, P320 M17/M18/X5 Legion 9mm

After installing this parts kit, I noticed the trigger reset felt more positive. It’s hard to explain, but the little springs and pins just gave a fresher, cleaner feel to the internals. Took a little patience during install, but once it was done, it was an easy recommendation to fellow P320 shooters.

I bought this kit to have on hand just in case something wore out or got lost during maintenance. After assembling it on my “project” P320, I realized it’s not just an emergency spare — it genuinely refreshed the overall feel of the gun. Definitely keeps in your range bag or safe for future use.

I liked how the kit is packaged — parts were clearly labelled and easy to identify. That helped keep assembly organized and reduced guesswork. The quality felt good and it made re-stacking springs and pins much less frustrating than piecing them out individually from random bags.

Everything fit perfectly with no problems, but I’ll admit installation wasn’t a quick job for me. If you haven’t worked inside a pistol before, take your time and reference a guide or manual. Once it’s all assembled, though, the performance improvement makes that extra care worthwhile.

Picked this up after noticing my shooter P320 was starting to feel a bit “sloppy” in the fire control group. Replacing the springs and pins made a real difference. It’s not night and day, but the overall feel of the pistol — especially during reset — is more crisp and predictable. I’d buy again.

My P320 has seen a lot of range time, and after thousands of rounds, it was overdue for a parts refresh. This kit gave me fresh springs and pins where needed. Took my time putting it together and now it feels smoother than it has in years. Excellent option for long-term P320 owners.

I’m a hobbyist who enjoys doing my own basic gunsmithing. This kit had all the small parts I would have otherwise had to source individually. The parts are organized and labeled, and once installed, the pistol ran consistently through multiple range sessions. Only minor gripe is that a couple springs looked a bit compressed from shipping, but function isn’t negatively affected.

I priced OEM springs and pins separately from SIG and it was going to cost me almost twice as much. This combined parts kit was a better deal and included everything in a nice organized set. Quality was great and fit was precise. Installation wasn’t trivial, but if you’re mechanically comfortable, it’s a good investment.

I bought this parts kit after a friend recommended refreshing the internals on older pistols. It took a weekend, but swapping in all the new springs and pins has noticeably reduced mis-feeds and hang-ups. It’s hard to quantify, but the gun feels more “confident” now. Worth it if you want your P320 to feel like new again.

Had my P320 for years and figured it was time to replace some internal components. This kit had everything I needed. Springs felt like the right stiffness and pins were solid. After a few hundred rounds post-installation, things still cycle smoothly and the trigger reset feels reliable. Very happy with the completeness of the kit.

I ordered this kit to replace worn parts on my carry P320. I was a little nervous pulling apart the fire control group, but once I took my time and followed a guide, the kit worked great. All the pieces fit without forcing anything. After reassembly, my pistol’s action felt noticeably cleaner and more consistent.

I bought this parts kit to refresh a tired SIG Sauer P320 I bought used. The pins, springs, and small parts came in perfect order — everything fit just like OEM. Installation took a bit of patience, but once it was done, my striker reset felt crisper and function was smoother overall. Great value for anyone rebuilding or refreshing their P320.
