Finally a 507k that makes sense to buy. - Holosun HS507K X2 Compact Pistol 2x 0.58 x 0.77 in Reflex Red Dot Sight

I purchased a 407k with 6moa dot a couple of years ago. It made alot more sense than the 507's 32 moa circle to me. This however, changes things. The circle is only visible when you are off target. Instead of a distracting ring around my dot, I now have a helpful guide for quicker follow up. On top of that, primary arms is actually backing up these Holosun Elite models with their own lifetime warranty. This is a huge improvement over a standard Holosun Elite warranty in my opinion.

Fit was a little looser this time around compared to the 407k I tried out. It took some work and a little more red loctite than I would have expected to get it mounted well.

I wish this had been my first pistol dot. These things are really easy to get used to.
