DPP Titanium Adapter Plate for Glock 43X/48 MOS Hellcat OSP with M4 Thread Holes and Holosun 407k/507k - GL-H07KA

It is a perfect fit for the Glock 43x. Very sturdy and easy to install. Comes with pre-loctite screws. Best value for the money.

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.

Perfect fit

It's fix perfect.

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!💯🙂👍🏻

Great fit

This was a great product that met my expectation.

This was a great option for affixing my Holosun 507k x2 to my G48 MOS. I was not excited about the idea of taking a dremmel or a file to the slide of my brand new sidearm. Also, all of you Glock fanatics know it is easy to blow a lot of $$$ In customization options, and the small parts/accessories can start stacking up. I opted for this option vs. the bigger competitor primarily due to the price point. Some other reviews scrutinized fitment - this was absolutely not an issue for me. Literally dropped right into the MOS slot with no wiggle or jiggle. The attached photos make the plate appear glossy; this is due to me applying oil to either sides of the plate to minimize issues with metal-to-metal contact points. Packaging arrived nicely. Everything fit into a nice plastic container (which is currently housing the Glock cover-plate and screws). Speaking of screws, the ones provided in the packaging come previously “locktited”. I had some spare to apply to other areas as back-up. Now, range time. After sighting in the optic, I wanted to verify how co-witnessing would work with my stock irons (not suppressor height). I could barely make out the front post when witnessing - but it was doable. The caveat to this comment is beware of the optic you are using, if you are also concerned about cowitnessing. The 507k’s have a notch cut out so that co witness is possible - other optics may not. Be realistic in your expectations with this. I purchased this setup to run an optic on a compact-carry firearm. I plan to primarily use the optic. I will continue to practice with co-witnessing, in case of electronic failure. It’s okay to go with this budget option - but do not “cheap out” on the optic. That may help with any gripes. I’m very satisfied with my purchase and do not expect to experience any issues. **** Update - bought Ameriglo GL-429 iron sights - huge improvement with co witnessing along with the optic. Good deal around $40. I’d still prefer to go this route vs. paying $60+ for a mounting bracket.
