SIG SAUER P365 Modular Optic System Cover Plate Review

First Impressions of SIG SAUER P365 Modular Optic System Cover Plate

The SIG SAUER P365 redefined concealed carry with its impressive capacity and shootability in a compact package. However, for those of us who prefer the clean lines of a slide without an optic, the Modular Optic System (MOS) cut can feel like a gaping hole. The SIG SAUER P365 Modular Optic System Cover Plate offers a simple solution: a sleek, color-matched plate to fill that void.

My journey to this little piece of aluminum began with a philosophical debate: red dot or no red dot on my carry gun? I ultimately decided that, for my needs, the iron sights were sufficient. The resulting MOS cut felt incomplete, aesthetically and practically.

Unboxing the SIG SAUER P365 Modular Optic System Cover Plate was underwhelming, as expected for a small piece of metal. However, the initial impression was positive. The aircraft-grade aluminum felt solid, and the finish, which I ordered in black to match my slide, appeared flawless. I immediately appreciated its simple design.

Compared to other cover plates on the market, the SIG SAUER offering seemed a bit pricey. However, I’ve learned that with firearm components, especially those for a SIG SAUER, you often get what you pay for in terms of fit and finish. Aftermarket options exist, but I wanted to ensure a perfect match and a secure fit. My initial reaction was cautiously optimistic. The price seemed a little high, but the promise of a seamless integration with my P365 slide was alluring.


Real-World Testing: Putting SIG SAUER P365 Modular Optic System Cover Plate to the Test

First Use Experience

The primary testing ground for this cover plate was my everyday concealed carry routine. I carried the P365 with the cover plate installed daily for a couple of weeks, assessing its impact on comfort and draw speed. Installation was simple, requiring only the removal of the screws securing the MOS plate and replacing it with the cover plate.

Performance in real-world conditions was unremarkable, which is exactly what I wanted. The cover plate stayed securely in place throughout daily activities. No amount of jostling caused any loosening.

The improved feel was immediate. The smooth surface of the cover plate eliminated the slightly sharp edges of the MOS cut. I found it now provided a more comfortable, snag-free draw from my IWB holster. No issues arose during this initial period, only a growing appreciation for the simple solution it provided.

Extended Use & Reliability

After several months of continuous use, the SIG SAUER P365 Modular Optic System Cover Plate has proven itself to be a reliable and worthwhile addition. There are no signs of wear and tear on the finish. The anodizing has held up beautifully against the daily grind of concealed carry.

Maintenance is virtually non-existent. A quick wipe-down with a lightly oiled cloth during regular firearm cleaning is all it requires. My previous experience with aftermarket firearm parts, especially budget options, taught me to be wary of long-term durability.

This cover plate exceeded my expectations. It has maintained its tight fit and flawless finish. It outperforms cheaper alternatives I’ve used on other firearms.
