Holoson bullet-proof sub-compact red dot and a perfect fit on the ruger max-9 - Holosun Sub-compact HS407K-X2 1x 6 MOA Dot Red Dot Sights

This sight is build like a tank and was a perfect fit on my Ruger Max-9. Ruger uses permanent red thread lock on the slide plate which can only be removed if heated. You don't want to put heat directly on the slide, so I took the Ruger supplied hex wrench and held it by the long end with a small vice grip and while the wrench was inserted in the screw I heated the middle of the wrench with a small micro torch. Within 20 seconds the heat was transferred to the screw and I immediately had another hex driver ready to remove the screw. Both screws came out with almost zero resistance using this method. If you don't heat the screws using this method you can strip the head and then it's off to a gunsmith. Some folks say this won't fit the Ruger Max-9 because it is a X2. That is not true! This is a perfect fit. The X2 varient has the same foot-print as the original but the controls are laid out horizontal on the X2 which is much better than the original vertical arrangement. Mine falls asleep after 10 minutes and wakes up the moment I move it. By holding the + button for 3 seconds you can lock the buttons to maintain the same level. MOST IMPORTANT is many sub-compact red dots automatically dim in low light and don't even come on in total darkness where the Holoson will. That is a big reason I bought it so the dot is visible when I hit my strobe light. Not even getting a laser for the Ruger since the Holosun won't give your position away until your ready to engage. One more thing, Optics Planet had the best price and very fast free shipping with Sunday delivery. Plus they gave me $20 off my next purchase in bonus points for buying this red-dot. If you get this Holoson you will wonder how you ever lived without it on your carry gun. Best money I ever spent.
