Essential upgrade - Volquartsen Firearms Extended Bolt Release for Ruger MK IV

This extended bolt release provides way more surface area and creates a flat shelf for your thumb to catch making it way easier to operate. The stock release is very low profile but it's unecessarily low. I found my thumb searching for the stock release and sometimes sliding off either direction. With this extended bolt release those problems are eliminated. I was able to install it in only a couple minutes by just taking the handgrip off. The extended release is made from a bit thicker metal than the factory release so when I replaced my grips I did have to sand them down a little bit in order for the release to operate but it wasn't a big deal. Overall I recommend this extended release and don't know why Ruger doesn't just put these on all their Mark pistols right out of the factory.
