Frequently Asked Questions

What is the RDIH SFS system and how does it benefit a Browning Hi-Power?

The RDIH SFS (Safe Fast Shooting) system allows a Browning Hi-Power to be carried safely in a 'cocked and locked' position, but with the hammer automatically pushed forward to a neutral position. This enhances safety while maintaining readiness for a quick draw and firing.

What are the key trigger and sight upgrades on this custom Hi-Power MKIII?

This custom build features an Apex Two-Stage trigger for improved pull and reset, and a Trijicon HD Tritium front sight paired with a Heinie Mil-Spec Ledge rear sight for enhanced low-light visibility and aiming.

What aesthetic modifications were made to this Browning Hi-Power MKIII?

The pistol received a Graphite Black Cerakote finish, custom facetting on the front and back straps for improved grip, and orange and black G10 VZ grips for enhanced ergonomics and a unique look.

What is an 11-degree barrel crown and why is it important?

An 11-degree barrel crown is the angle cut at the muzzle end of the barrel. This precise angle helps to smoothly guide the bullet as it exits the barrel, potentially improving accuracy and preventing gas leakage that could affect bullet flight.
