Does this come with screws to install on a p 365 XL?

I haven't bought the 507K yet, but I do have the 507C. It came with everything I needed to install and adjust, including the screws. I can't imagine the 507K wouldn't come with everything as well.

Is the Holosun name/logo, and model/serial number, painted on, or is it a decal? I've been waiting months for a HE508T-GR-X2, because it's all black. Expert Answer

Yes they are painted on there on the sides of the red dots.

Small red dot for EDC by Simon, Verified Owner, November 22, 2025
I had a doubt about adding red dot to my P365. It was supposed to be small for every day carry and adding accessories would not be desirable for the purpose. I thought that I would try and added HE507K-GR-X2. The installation was straight forward. I ...

Highly recommended HE507K-GR-X2-ACSS by JLC, Verified Owner, January 22, 2026
I’ve been running the HE507K-GR-X2-ACSS for EDC and it’s easily one of the best micro pistol optics I’ve used. The ACSS Vulcan reticle is the real standout. On the draw, the outer reference ring immediately guides your eye to the center dot if your ...

Wonderful green dot by Argos, Verified Owner, April 20, 2024
I have purchased cheaper dots for rifles, but I have never spent money for a higher end sight. I got this for my 10mm springfield, and I love it. In daylight, the objective is pretty crisp and clean. In low light it can get a small blur. This is defi...
