Frequently Asked Questions

What makes the Sig Sauer P365 DH3 a competition-ready pistol?

The P365 DH3 is designed for competition with its lightweight build and a slide-integrated expansion chamber that vents gas to significantly reduce felt recoil, allowing for faster follow-up shots and improved control during rapid fire.

How does the P365 DH3's recoil reduction system work?

It features a slide-integrated expansion chamber, often called a 'slide comp,' which acts like a small muzzle brake built directly into the slide. This system vents propellant gases upwards and forwards, counteracting muzzle rise and felt recoil.

What are the price differences between the P365 DH3 and DH3 AXG models?

The standard P365 DH3, typically featuring a polymer grip, retails for around $900. The P365 DH3 AXG, which includes an aluminum grip, is priced higher, around $1200.

What are the 'go-fast holes' on the P365 DH3 slide?

'Go-fast holes' is a term for the lightening cuts and ports on the slide of the P365 DH3. These are designed to reduce the slide's mass for quicker cycling and to help dissipate heat generated during firing.
