Same form factor, 8+1 or 16+1. hmm...I'll choose 16.. being a "different caliber" isn't a big deal, to me. I've used more than one calibar in the past. I think I can handle that particular issue.

What plate did you use, if any? I have the 507k, but don’t want to file the rear lugs down.

What I used:
C&H Plate for Holoson..

S&W M&P® SHIELD PLUS to Holosun 407K / 507K - C&H Precision Weapons

S&W M2.0™ SHIELD S&W M2.0™ SHIELDThis is the optics adapter plate for the M&P® SHIELD™ which allows you to mount the Holosun HS407K X2 or HS507K X2. The Holosun K series open reflex optical sight designed for concealed carry pistol applications.

It's super thin... I don't think filing down the lugs is worth it, unless you want to save $50.

I actually bought mine from "Aim Surplus". I knew nothing about them, but at the time C&H Precision was out of their own part. I found the C&H Precision plate at Aim Surplus and decided to go with them to get it. Before it came, it was back in stock at C&H.


Also an option, the DPP Titanium plate for the Shield Plus and Holoson 407. Only reason I didn't try this was availability. Its like $22.
