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.
