Fits great on the springfield echelon. I love the site so far.

Love this optic. Own the 320 X Compact Spectre. So nice to have this optic as a direct fit (without use of any adapter plate). Have only used on indoor range thus far. Love having an MRS and the clarity is amazing. Study enough that I could use it to rack my pistol on anything in an emergency if needed. Since I have not used outdoors, I can not attest to the benefits of the closed emitter, but assume it will be beneficial in inclement weather conditions.
It is more expensive than most Holosun optics, but offers everything I need in one for my pistol’s use. Highly recommend. I am also in the process of purchasing a 320 AXG Legion to begin competition and will get another of these optics for the pistol as well.

Easy to adjust and handles the recoil of the 10mm. Perfect fit on the Sig P220 Legion 10mm.

Don't be hesitant to purchase this optic for your p320 platform or your Delta point pro platform whichever you have this is a really good optic it's ipx8 waterproof not six for some reason the box says ipx6 but it's not so their website says ipx8 but this is a fantastic optic I kept on taking it on and off because I wasn't sure about the auto adjust not that it doesn't work it works great the auto adjust is fantastic but I just like manual I'm old school I guess and the 2 moa dot I'm not a fan of the two MOA dot but that's all right but you know what I just keep going back to it because it is it just put it on and forget it it's durable the glasses great and it just works I definitely definitely recommend it

I wanted an optic for my new Echlon and after looking at the many options, and reviews on line, I purchased the SCS 320 from Freedom Gorilla. Shipping was free and very fast. Would I recommend this company? You bet. I am now looking to get an optic for my wife’s S&W Equalizer.
