Adapter Plate for Glock 43X/48 MOS Hellcat OSP Holosun 407k/507k - GL-H07KA

This adapter plate works flawlessly. I’m running a Holosun 407k green dot on my Hellcat Pro for concealed carry, and this DPP Titanium plate made the installation clean and rock solid. What I Liked: Solid Build: The titanium construction feels premium—lightweight but incredibly durable. It gives me confidence it’ll hold up under regular carry and use. Flawless Fit: It lined up perfectly with both the Hellcat OSP and the Holosun 407k. No wobble, no gap, just a snug, secure fit. Low Profile: Keeps the optic seated low enough to maintain a good co-witness with iron sights (if that matters to you). Easy Install: Came with everything needed, and installation took just a few minutes with no issues. Final Thoughts: If you’re running a similar setup, this is a must-have. Zero regrets. It’s been rock solid for my CCW, and I trust it to perform every time.

Attached a holosun to my hellcat.

Great fit

I needed a plate to mount my Holosun 407K on a Springfield Hellcat Pro. I tried to mount it directly to the slide but it didn't fit properly. This plate interfaced perfectly and the supplied screws were the correct size and length. The screws came with blue loctite already applied so everything went together perfectly. Unlike many plate systems, this one was reasonably priced.

This fits perfectly and is well made. Even the little plastic case it comes in is nice, much nicer than the little ziplock bag the CHP plate comes with and that one is $50 compared to under $25 for the DPP. The screws are nicer that the CHP too. These look just like the screws Holosun sends but they’re the correct length. The CHP plate comes with silver screws that aren’t even flat top. It doesn’t look good with a black optic. I misplaced my screws and they sent me a replacement set right away, no questions asked other than which Holosun model I was using. Stellar customer service! Don’t hesitate to buy from them. It’s a tiny bit thicker, barely noticeable, than the CHP plate but at half the cost and still being able to co-witness it’s a no brainer. Nicer packaging and screws are awesome added bonuses too. They get 5 stars from me, I’d give them more if I could. *EDIT* These guys are top notch, stellar customer service! Not only is their product great, I messaged them yesterday for help and Henry was very quick to respond. Not only did they send me what I needed but he went above and beyond that and I got it today, the very next day! Outstanding! Thanks again Henry! I’ll definitely be coming to DPP for any plates I need in the future!💯🙂👍🏻
