Great Trigger Package
This makes a Ruger Mark IV into a competition pistol. With the ability to tune your trigger reset it allows for very fast second shots and morel. All of my Mark IV triggers are replaced with this package. I shoot 3 pistol competitions every month.

Solid Upgrade
I've installed Volquartsen accurizing kits in multiple guns. This last kit was for a new 22/45, and it met all my expectations based on previous purchases. Improved trigger pull (less creep, smoother, lighter) significantly. Highly recommended.

Great Upgrade
The factory trigger was not great on my MKIV but I have used this brand to upgrade another firearm and was very satisfied. I watched the brownells video on the installation and from the manufacturer it made the installation pretty simple. Some parts of the installation were a little frustrating due to the small size of some of the parts. I would suggest anyone installing this yourself to have some small needle nose players and a punch to line up parts. Tigger has no creep & a clean break.
