General Holosun pistol optic thread

I don't understand the disclaimer: "Important Note:



This model will fit Sig Sauer P365 XL only. It will not fit any other models. Please do not buy this model unless you have a P365 XL."

Is this model somehow specific to that particular gun only? And if so...why?

I got my 507K from that guy. He wanted me to confirm I was putting it on a sig. I told him no, I'm having my slide milled for it and he replied saying he just wanted to make sure because someone bought the sight thinking it would just drop onto any ole gun. Apparently the Sig is the only model the 507K will work with without milling or a special plate.

What is it rubbing up against? I’ve had an RMR that I’ve carried since the release of the MOS system that shown no sign of wear on the buttons.

It hasn't rubbed on anything to my knowledge which is the weird thing. Here's a picture of the RMR.

It’s weird. I looked on Agency Arms site and they list the 507k X2 as one of 2 options for the G48/43x. They sell the 507k x2 for like $45 more than the link provided.

I wonder what’s up with that. If it’s good to go on the 48 one may as well save a little at that link except for the fact it lists it there as 365xl only.

Is Agency gtg for milling and red dot install btw?
Does the RMRc fit the 48?

The 407K/507K needs an adapter plate (or milling a couple of the bosses) to mount to the Glock 43X/48 MOS.

Agency is rad for milling. I have one M&P 2.0 slide milled by them for an AOS now and I’m waiting for another Glock 34 AOS slide and a mid-priced done-up frame to be ready. A bunch of our guys have Agency cuts and guns as range toys and like ‘em.

Excellent. I actually just bought a 2.0 compact.

I have intentionally left my 509T on manual, at a pretty high intensity, to check battery life. Been well over a month, and the battery is still going strong.

Interesting concept. Larger outer ring reticle outside the view when the optic is aligned but shows the reticle when it is misaligned.

What does the Brownells optics 48 slide need in order to mount the 507k?

Grind off 2 of the bosses. Here’s a buddies.

I've got a 507c, 2 507cV2s, and 2 510cs. All have been 100% flawless so far. Thousands of rounds on MKIIs, hundreds on G17, hundreds on 9mm AR.
