Frequently Asked Questions

What are the main benefits of the Volquartsen Ruger MK III Performance Upgrade Kit?

The Volquartsen kit significantly improves the Ruger MK III's trigger performance by reducing take-up, eliminating creep, and lowering the pull weight from the factory 4-5 lbs to a crisper, more precise trigger pull suitable for target shooting.

What is a critical step to remember before installing the Volquartsen trigger into the Ruger MK III?

It's crucial to install the pre-travel and over-travel set screws into the Volquartsen trigger *before* placing it into the pistol's frame. Use a drop of medium-strength thread locker on these screws.

How do you handle the Ruger MK III's magazine disconnect safety during disassembly?

The empty magazine must be kept inserted for certain disassembly steps. For instance, after removing the mainspring housing, the empty magazine allows the trigger to be pulled to help remove the bolt.

What are the recommended adjustments for the trigger's set screws after installation?

After installing the kit and performing safety checks, adjust the pre-travel and over-travel set screws. A good starting point recommended by the video is approximately 0.075 inches for both adjustments.
