This adapter is essential to fitting a Holosun 507k on a Shield Plus. It fits perfectly, and makes for a great optic combination.
A platform that offers smooth and fast draws. So easy to carry and conceal your weapon of choice. Wearing dress pants or jogging shorts? Not a problem!
Sat perfectly on my S&W and looks well made. I did have to grind the posts a little bit to get the optic (Holosun 407K) to sit flush which took all of one minute to do. I haven’t shot the firearm yet since mounting but will modify review if anything goes sideways for whatever reason
Ok Price for a shim plate for today I guess. Lost co-witness sight view. But all in all it does what it's supposed to.easy install.
