Springfield Hellcat OSP, RDP, PRO for Holosun 407K, 507K - Aluminum - DPP

Seamless installation of the optic plate for a Springfield Hellcat Pro OSP equipped with a Holosun 507K. Bore sighted before range shooting and didn’t have to change the elevation or windage. Shot 4 inch groups at 25 yards.

I put a 407 on a Hellcat pro using this adapter and it works. Only 300 rounds so far so no torture test or anything.

The plate fit nice and tight and allowed for a nice tight mount for my Holosun 407k. Thanks for the recommendation Freedom Gorilla!

The products I ordered were great no complications. But I was really impressed with the company and service over all else. Will come back here to buy all my optics.

In my opinion, Holosun Optics are one of the best brands and top selling optics on the market. I have 8 pistols and they all have Holosun Optics mounted on them. If you’re in the market to upgrade your pistol, you can’t go wrong with one of their products. I won’t bore you with details on the features of this or any of their optics. You can read that for yourself as well as viewing the YouTube video the guys from Freedom Gorilla provides for your make/model pistol. Again, giving praise to the Holosun products is strictly my opinion. Happy shooting!!

Perfect

Plate fit perfectly, allows co-witness with sights on pistol. I would purchase again!

I Love It !!

Exactly what i needed!

I picked up two Holosun 507Ks one for my Shadow Systems CR920P and another for my Hellcat Pro Comp. I’m not a professional shooter or anything like that, just someone who likes to train regularly and have reliable gear.
Setup was straightforward, and both optics fit nicely once mounted. The glass is clear, the reticle is crisp, and the brightness settings are easy to dial in depending on lighting. The battery life seems excellent so far, and the shake awake feature actually makes a difference when you’re carrying daily.
What I really appreciate is how consistent the 507K has been on both platforms. Zero held perfectly after range sessions, even with a couple hundred rounds through each gun. It’s not flashy or overhyped it just works, and that’s what matters most to me.
If you’re looking for something dependable without paying Trijicon prices, the 507K hits that sweet spot. Nothing fancy, just solid performance and peace of mind.

Excellent.

Everything lined up nicely and holding everything perfect for the last 500ish rounds

Great product, perfect fit.

Good product. Prompt service from the customer support

Fits like advertised.

This plate positively locks in place and is very THIN! So thin that I can still use the iron sights through the optic’s window (but just barely).

You guys frickin rock

Love this

Item just as described, works great.

Your service was great. I didn’t like the product. So I’m returning it.

You where the only one to have the item

Perfect fit and finish, great service!!

Holosun optics are the best! Your service is great. Shipping isn't to good but I chalk that up to the holidays!'

Can't co-witness with iron sites without an adapter plate. Holosun should add two holes in the rear of the base to allow mounting without a plate on the Hellcat. Crimson Trace does this and will co-witness.

Delivered promptly & easy to install.

Shipment came on time the DPP plate works great mounted my optics no problem. I will be using Freedom Gorilla again. Charles Sparks
