So picked up a pumped out slide. Got it off eBay that somebody polished to a high brightness. I installed a slide finishing kit and a Osights S.

Wow...polishing that slide must have taken many hours !! My shoulders hurt just thinking about it!
Sharp looking little 365 !!

Yep I don’t know if it hurt but I wouldn’t ever put that much effort into it. But I do like the results.

Have to let us know what you think about that O sight. I'm a big fan of their lights.

I recently picked up an Osight s and thus far I’m impressed. Clarity is excellent and auto adjust seems to be just right for the lighting. I have to contrast this to the Holosun SCS (PDP version) which is way too bright at all times. Only has about 100 rounds shot (SW Equalizer) and has kept zero this far.

I’d agree Olight prolly reversed engineered this based on Holosun EPS. Reports of early issues with Osights have been reported as fixed. Time will tell regarding longevity. Hopefully, if successful, they will keep prices down unlike Holosun whose prices have been creeping up.
