Questions & Answers
How does it mount to the slide?

You will need to remove the rear sight. The red dot comes with a piece that will slide into the rear sight dovetail. This piece has the posts for the optic screws. You’ll place the red dot directly on the slide. You then install the red dot screws and it’ll tighten up to the slide and with that dovetail piece. Make sure to torque the screws to spec and witness mark them.

Green. I don’t know if it comes in red or not yet.

Does not disappoint by Kenneth, November 12, 2025
after running some dry draws, holstering/rehousing, and cycling the slide a few hundred times, I can vouch—it stays tight, zero shift, no wobble.

spot on sight by Greenmachine1, Verified Owner, April 3, 2026
This sight works great for distance. It really makes up for the LCP MAX short sight radius. Money well spent.

Never seen anything like it before! by Larry1, November 10, 2025
I love my LCP MAX and never thought I’d be able to find an optic for it—until now. I’m genuinely excited about this one. There are plenty of lasers and lights available, but if you’re looking specifically for an optic, this is the one to get. It moun...

I was excited to try this out . I carry my max 380 daily, at the range not bad had to adjust it a bit but its there. I'm out late a lot and this is where this thing becomes completely useless. The dot is so faint you cant even see it. And in the dark...
