Anyone know if the 507k has a unique foot print or is it the same as some other RDS? Having trouble finding that info out in internet land.
Yes and no. It’s a similar footprint to the Shield RMSC, however slides milled for the RMSC must have the rear posts removed and the front posts shorted by .015 for the 507K to mount correctly.
Thx…that was sort of what I thought. Its not a drop in for anything like the C is a drop in for a RMR.
I have a 507K on my G43X MOS. C&H Precision has an adapter plate for the K which is what I use. Works great. My pistol RDS experience has been with RMRs mounted on 2 other glocks. The 507K my first Holosun optic and I REALLY like it.
I have the CHPWS adapter plate on my Gen 5 G19 MOS with the 507K V1. I had to do some adjustment to the forward edge of the plate before it would fit fully flush, but the posts and rear were fine.
Thanks guys. It looks like the K is in it’s own little niche, and the mount makers are having to catch up a little.
I have a 507k direct mounted a p365 XL. The 507k shares a footprint with Shield RMS and the Romeo 0. I’m digging mine.
So the footprint is a direct one for one without modification with these 2 RDS’s?
That is my understanding. The p365 XL is obviously made for the Romeo 0, and I’ve read that the RMSc fits directly, but haven’t seen it first hand. However, the 507k fits like a glove.
Bumping this thread up because I just bought a G48 MOS and the SIG Romeo Zero. I was more interested in the 507k but the dealer didn’t have one in but still I wanted MRDS to try out.
Hearing that the 507k fits the same area as the RZ is great. I had been reading conflicting reports on if it would fit the G48 MOS(I guess no one is playing with one yet shrug).
I feel the RZ is a mixed bag and I have a feeling a 507k is in my near future.
For the 48/43x mos you do as posted above:
Or buy the chpws plate
Thank you for that. I kept seeing back and forth talk it was confusing me. I couldn’t find any videos that discussed the actual mounting method either (until today, I finally found one on the 507k and the mounting plate you suggested on a 53X MOS).
Hope it is ok to ask a question in this thread.
I have G43X MOS and purchased the Holosun 507K and CH plate.
What sights are you using? Factory Glock?
I put on Trijicon HD XR.
Confessing the first time to the range with the new Trijicon and the Holosun was a bit busy for my eyes/brain.
Have since removed the Holosun and plate…back to Trijicon HD XR for now
Am open to suggestions/recommendations.
With my 43X MOS w/ 507k I came with Ameriglo Agency sights. I kept the front but wanted a blacked out rear sight. I called Ameriglo to ask which rear sight I should go with. They went and measured several of their sights on a 43X MOS and called me back with an answer. They said the GL 414 is what I wanted even though their site specifically says the GL 414 is not compatible with the G43. They even gave me even game a coupon code for it. The GL 414 fits & works perfectly.
Thank you ! !
I had heard/read Ameriglo would be the brand but when I called I did not get directed to 414.
Good to know 414 works for you…assuming you are not lower 1/3.
