Frequently Asked Questions

What is the SFS system on a Hi-Power?

The SFS (Safe Fast Shooting) system, often installed by specialists like BH Spring Solutions, allows a Browning Hi-Power to be carried safely with the hammer down. It enables the user to quickly bring the hammer to a cocked position for immediate firing, offering a carry method similar to 'cocked and locked' on a 1911.

What are the benefits of an 11-degree barrel crown?

An 11-degree barrel crown is a gunsmithing modification that angles the muzzle end of the barrel. This precise angle helps ensure the bullet exits the barrel smoothly and consistently into the rifling, which can improve overall firearm accuracy and shot grouping.

What upgrades were made to the Browning Hi-Power MKIII in this video?

The custom Hi-Power MKIII features an 11-degree barrel crown, Trijicon HD front and Heinie Mil-Spec Ledge rear sights, the RDIH SFS system, an Apex two-stage trigger, custom grip facetting, a beveled magwell, VZ G10 grips, and a Graphite Black Cerakote finish.

How does the Apex trigger improve the Hi-Power's performance?

The Apex trigger upgrade provides a two-stage trigger pull, characterized by a distinct take-up phase followed by a clean, crisp break and an audible reset. This enhances trigger control, accuracy, and shooting speed compared to a stock Hi-Power trigger.
