Let’s Dive into SIG SAUER M17/M18/P320 Corrosion-Resistant Slide Completion Kit w/Extractors
The SIG SAUER M17/M18/P320 Corrosion-Resistant Slide Completion Kit w/Extractors offers a convenient and reliable solution for completing or upgrading your P320 series pistol slide. This kit, manufactured by SIG SAUER, includes all the essential internal components except for the barrel, sights, and recoil spring assembly. It promises factory-quality parts and improved corrosion resistance, making it a compelling option for both new builds and replacements.
My journey with the P320 platform began a few years ago, drawn by its modularity and the positive reviews surrounding the M17 and M18 variants. After running thousands of rounds through my P320, I decided to build a dedicated suppressor host upper. I needed a reliable parts kit to complete the new slide assembly, one I could trust to perform without fail.
Upon opening the package, I was immediately impressed by the quality of the components. The parts were individually packaged and well-oiled, suggesting meticulous attention to detail. The finish appeared durable and uniform, consistent with SIG SAUER’s reputation for producing high-quality firearms.
Compared to some aftermarket slide completion kits I’ve seen, this one exuded confidence. Some third-party kits use questionable alloys or have rough finishes, making them less desirable. I chose the SIG SAUER kit because I wanted factory reliability and didn’t want to risk compatibility issues with aftermarket parts.
My first impression was one of excitement and relief. I knew I was getting genuine SIG SAUER parts, which gave me peace of mind knowing that the slide would function reliably. The quality of the parts was visibly superior to cheaper, non-branded options.
Real-World Testing: Putting SIG SAUER M17/M18/P320 Corrosion-Resistant Slide Completion Kit w/Extractors to the Test
First Use Experience
I tested the SIG SAUER M17/M18/P320 Corrosion-Resistant Slide Completion Kit w/Extractors at my local outdoor shooting range. The weather was typical for a late spring day – slightly humid with a chance of rain. I put the completed slide on my P320 frame and ran roughly 300 rounds through it, using a mix of 9mm FMJ and hollow-point ammunition.
The performance was flawless, even in the somewhat damp conditions. Ejection was consistent and strong, and I experienced no failures to feed or extract. The primer strikes were deep and centered, indicating proper firing pin engagement.
Installation was straightforward, although I’ll admit it requires some familiarity with the P320 platform. Because I’d disassembled P320 slides before, the process took me about 20 minutes using basic gunsmithing tools. Novice users might want to consult online tutorials or seek assistance from a qualified gunsmith, as the product description warns.
I didn’t encounter any issues or surprises during the initial range session. The slide functioned as expected, and the improved corrosion resistance gave me confidence knowing that the internals were better protected against the elements.
Extended Use & Reliability
After several months of use and approximately 1500 rounds fired, the SIG SAUER M17/M18/P320 Corrosion-Resistant Slide Completion Kit w/Extractors has proven to be remarkably reliable. The finish has held up well, showing only minor wear marks on the extractor. The parts continue to function smoothly without any signs of degradation.
I regularly clean and lubricate the slide components after each range visit, following SIG SAUER’s recommended maintenance procedures. The parts are easy to access and clean, and I’ve experienced no issues with rust or corrosion, even after shooting in humid conditions. The SIG SAUER kit has definitely outperformed my expectations.
In comparison to previous experiences with aftermarket completion kits on other platforms, this SIG SAUER kit is a clear winner. I’ve used kits with extractors that failed after only a few hundred rounds. This SIG SAUER kit provides exceptional reliability and peace of mind.
