Yes. This product is compatible with the Sig p365 regular. However, you will either need to have the slide milled or buy an adapter player to attach the sight.

No, only the P365XL with the precut optics cut will work. In order to put this on a regular P365 you'll need to have the slide machined.

The p365 does NOT have an optical cut slide, therefore you would need to send your slide in to someone who does optic cuts (which is what I am doing currently) or you would need to buy an aftermarket slide. I dont recommend the second option mostly because of cost. Jagerwerks will do the slide cut for $125, whereas most aftermarket slides are between $250 and $400

This will work on the P365XL & P365X, but the P365 is not factory milled for an optic.

I’ve seen different answers on this: I have a p365X with Romeo Zero optic. Want to swap to this. Will it fit with current plate?

A P365 straight from the factory (as I write this, 1/7/21) cannot take this sight. The slide on a P365 can, however, be milled to take this sight.

I have the 407K on my regular P365 but you will have to have your slide milled. I had mine milled.

Only if you have had the slide milled. Unlike the P365xl, the P365 does not have a cutout for an optic.

Not until you have the slide milled. The P365 is not optics ready.
