Researched several red dots for my Glock43X, CZ Shadow 2 compact and Apollo 11. Several YouTubers suggested the Holosun 407K Optic and Freedom Gorilla had it for a great price. Once in the cart, Freedom Gorilla provided some recommendations and I’m so glad I purchased the Holosun 407K Optic Cover. It was at a discounted price and fits perfect. Great addition and protection.
It could not be a better fit for a Sig P365!! (Especially the FDE ❤️)
In all seriousness, it is awesome, perfect.
The SCS PDP fit the gun like a glove, perfect for the range and everyday carry. If you are looking for a green dot for your Walther PDP F Series look no further the SCS PDP is it. Big shout out to Freedom Gorilla for making this purchase smooth with fast shipping you can’t beat it. I highly recommend Freedom Gorilla for your firearms needs. Thanks guys.
Works great! Had an issue sourcing screws as the included holosun screws were the wrong pitch for the Beretta apx a1 tactical and the mounting plate is proprietary to Beretta.
Once those were obtained, it mounted up fine. Also purchased a opticgard in fde to match the pistol rather than paint the optic.
Holosun runs great. Nice crisp reticle, holds zero, big window.
I love it.. if you have a gun with RMSc footprint it's the way to go without having to get an adapter plate..
Great fit, top notch product!!
Great customer service easy website to use and fast shipping.
Great service. Definitely buy from them again
After doing significant research on red/green dot sights for my Smith and Wesson M&P 1.0 PRO CORE in 9MM – I decided to go with a Holoson 507C Green DOT. First off it took some time to figure out whether or not the supplied optic plates would be compatible. Freedom Gorilla was very helpful in determining an adapter plate – in fact to my surprise Smith and Wesson supplied a RMR adapter which worked perfectly with my weapon. I am using the green dot with a 32 MOA circle. Having suppressor height sights on the weapon allowed for a shallow co-witness with the iron sights. Using Freedom Gorilla’s zeroing guide, I used a bore sight laser to adjust the optics for 50 FT. Unfortunately, the initial sighting was far from zero, I went out and purchased another laser sighting system to zero out the site and this also had significant issues with being anywhere close to center target. I have resorted to zeroing the sight to my co-witness front sight for centering at 25’ – the sight works but accentuates any slight movement of the weapon – making the sight pretty much irrelevant. Basically, I am better off with the iron sights vs. the green dot setup. Follow-up shots with the green dot are not accurate by any means – I am avid shooter for over 30+ years. Think twice or try a red/green optic before buying – it is not all that!
