Frequently Asked Questions

What is the unique 'Double Action Plus' system on the Lionheart Regulus?

The 'Double Action Plus' system on the Lionheart Regulus allows the user to manually push the hammer forward after racking the slide. This cocks the mainspring, resulting in a lighter, more consistent trigger pull for the first shot, similar to a single-action trigger, while still offering the safety of a hammer-fired system.

What is the heritage of the Lionheart Regulus pistol?

The Lionheart Regulus has a rich heritage originating from Daewoo Industries in Korea, who produced firearms for the military, including the K5 sidearm. It was previously imported into the US as the DP-51 and later produced domestically as the Lionheart LH9 before evolving into the Regulus.

How does the Lionheart Regulus's trigger compare to traditional double-action pistols?

Unlike traditional double-action pistols where the first pull is long and heavy, the Regulus's 'Double Action Plus' system precocks the hammer, providing a lighter and more consistent trigger pull for the initial shot. Subsequent shots also benefit from this precocked state, offering a more uniform shooting experience.

What are the key construction materials and features of the Lionheart Regulus?

The Lionheart Regulus features a durable 7075 T6 aluminum frame and a 4140 steel slide with a cold hammer-forged barrel for longevity. It includes G10 grips with enhanced texturing, Novak-style sights compatible with 1911 dovetails, and a Picatinny rail for accessories.

What are the different models of the Lionheart Regulus available?

The Lionheart Regulus is available in several models: the Beta is the compact version with a 3.7-inch barrel, the Alpha is the full-size model with a 4.1-inch barrel, and the Combat model is larger with a 4.7-inch barrel, suppressor-height sights, and a threaded barrel.
