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

It does when it was designed to do. Perfect mount for the optic and holds it in place. Very thin but strong definitely recommend.

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.

It's fix perfect.

You can spend a lot more on a lot worse. Perfect fit, quality part, great price.

The exact adapter I needed. Feels durable, zero issues installing.

Fits the 43x perfectly installation was quick and easy. Barely noticeable in appearance.

Perfect fit for my Glock 43x MOS with the Holosun 407k.

If you are reading this, you are probably trying to decide between the 2 main adapter plates out there and everyone seems to debate which one is better. One could spend hours looking at pics, reviews and opinions on both. I have both and one is the clear winner. Spoiler alert, the DPP is better in every way. Note: I dismissed DPP at first because it was cheaper, and sold on Amazon while C&H is known for their plates and quality. It couldn't be nearly as good, right? Boy, was I wrong. Here's why: Thickness: The elephant, first. The DPP is a 1/2 of a hair thicker than the C&H. See pics. If you had them side by side, you would feel silly even considering the difference. It is so negligible that it would be like a marathon runner ripping the corners off his number for a faster time. If you held one and waited a minute and held the other, you couldn't tell them apart. My dot only needed a slight adjustment after installing the DPP but that was most likely due to the re- torquing the mounting screws. Weight: The DPP is heavier. This is due to Titanium vs Aluminum and the DPP is more solid. Again, unless you held both at the same time you wouldn't notice. I prefer the DPP because of this. As far as weight and height, you are splitting hairs. It is not even a factor. Quality & Fit: The fit is what is the big difference between the two. The DPP wins this hands down. When you put the DPP on the slide without the screws, it fits perfectly with no wiggle and zero gaps. The C&H wiggles easily from side to side. When you set the 507k on top of the DPP plate you can pick it up and the plate will stick to the bottom because of the perfect fit. The C&H will not in any capacity. It's not even close. The reason I went from the C&H to the DPP plate is that there is a noticeable gap between the plate and 507k on the front end. I even tried reinstalling it but got the same result. If you pressed down on the sight, it would move. That gap attracted dust and debris and it drove me crazy. In all fairness, there is not a gap on my other C&H plate from a different slide by the same manufacturer.. Price: Hands down, the winner is DPP. If the DPP and C&H were the same price, I would still buy the DPP all day long. It is just a much better plate. I liked it so much I ordered a second one for another slide. I hope this helps others who are trying to decide.
