Most Helpful Positive Review Small upgrade, Big improvement
These sights are outstanding, made from quality steel and made in the USA! They're easy to install without a gun smith. I bought two sets to upgrade my MK IV 22/45 and my Stainless Steel Target model. The rear sight only needs to swap the sight blade so you don't have to push out the dovetail base. Height and windage are adjustable with firm clicks and will hold their set positions. The fiber optics are small but bright, making target acquisition much easier than the factory sights. These will fit on all Ruger MK IV series pistols EXCEPT those with the threaded barrel option. The William's fro...

Much better than stock sights

by Mobius, Verified Owner from GA, United States Written on May 2, 2026
Put these on my Ruger 22/45 Lite and now have a much better sight picture and faster target acquisition.
Pros:
  • Bright with good contrast.
Cons:
  • Rear sight fiber optics could be a bit larger which is my reason for 4 instead of 5 stars.
Best Used for:
  • Target shooting
Would recommend: Yes

Fire sight 633505

by Mark 4, Verified Owner from NV, United States Written on November 24, 2025
Good but no screws included. I wish you weren't such cheap skates and at least throw in a few screws especially after paying $75. for tiny metal bits of sights.
Pros:
  • compact
Cons:
  • No screws
Best Used for:
  • Targets
Would recommend: Yes

Great upgrade

by NT, Verified Owner from NH, United States Written on March 3, 2024
My Mk IV definitely needed this. My only complaint is for Ruger themselves: don't bother taking the dovetailed rear sight base off, just take that horizontal adjustment screw out and swap in the piece that houses the green sight. One minute install, no hammering.
Pros:
  • None
Cons:
  • don't bother with the dovetails!
Would recommend: Yes

Small upgrade - Huge improvement

by Knightshift, from WI, United States Written on March 13, 2022
I replaced the factory sights on my Mark IV 22/45 with these and I am very impressed. Very easy to install. You don't have to replace the entire dovetail, just swap the sight blades and away you go! Several videos on the web to show you how. The fiber optics are bright with a nice color contrast from front to rear. Elevation and windage are click adjustable with a small screwdriver. Solid construction and made in the USA!
