Big improvement over the original sight. Highly visible for quick front-sight acquisition. Comes with a red insert but the yellow works fine. Very easy installation.

I purchased this front sight as a replacement for my Ruger MK IV 22/45. It is a great improvement over the stock front sight, much easier to see and acquire the target. I highly recommend this replacement sight.

Beats Dawson and LPA for clarity and size correctness. Color is awesome. I would love to have this on my Sig P320 compact pistols.
