I don’t write reviews often but F1firearms deserves one. The Heckler and Koch Mounting Plate VP9 to Holosun 407K/507K/EPS is exactly what I was looking for. Good build quality, snug fit on my G23, and the price was the best I could find after checking multiple sites. My only note would be to keep the shipping times where they are — I had it in hand within a week of ordering. Will be a repeat customer.

Took a little longer to ship than I expected. Product itself is great though, fit my Glock 45 perfectly.
