Over the last few years, the popularity of concealed carry micro 9 pistols has increased dramatically, and the Sig P365 started it all. First introduced in 2018, the Sig P365 was the first concealed carry 9mm pistol with a high capacity of 10+1 rounds in such a small package. Being manufactured by Sig, it was also very reliable and accurate and, therefore, is the go-to option for concealed carriers all over the US and the world.

Slides

The factory slides on most Sig P365 pistols may not have an optics cut, which is one of the main reasons some shooters buy optic-ready aftermarket slides. You can also send your factory slide to a gunsmith for optics cut milling. However, that can be expensive and take a lot of time. Some aftermarket slides also have unique serrations and lightning cuts, which decrease the pistol's weight and can make it run a little faster. However, remember that you may also need lighter springs for sides that are considerably lighter than the factory slide. Otherwise, you may have some reliability issues.
