A Must Have
If you are upgrading your 22/45 than this as well as the thumb rest are a must... red looks great. Get the Volquartsen trigger upgrade as well, allow three hours for installation unless you are talented or lucky... but it is worth it.

Nice upgrade
Much easier to push down with your thumb, especially if your hand is a bit small. Looks great too.

Yes please thank you
The more aggressive & pronounced texture make the bolt stop release very smooth. It takes a small & predictable amount of pressure to release the bolt, even on an empty magazine.

Even for someone who is all thumbs, me, this was an easy install. It also works great. Love the red.

Extender Ruger Mark IV
I have put this extender on my Mark IV and what a difference when I release the bolt it is easier and more comfortable for me to reach with my right hand before the factory one was very difficult to reach and harder to release the bolt if you are having problems I highly recommend to put one of these Extender Bolt Stop on your Mark IV and you will feel the difference right away.

Aggressive Edges?
Very easy to install. I really like the red as in looks great on my wife s MK IV red lite. I haven t taken it to the range for a proper try out but here in my shop the edges are very aggressive on my thumb! And this is for my wife. We are destined to go the the range next week and I will try and update on how she likes it. I will contact Cori and see if I can chamfer the edges a bit with going through the red color. Still giving it 5 stars!
