This review explores the Heritage Stealth C-1010 and Wilson Combat ADP, both inspired by the HK P7's gas-delayed blowback system. While the original ADP design from South Africa offered unique mechanics, early US iterations like the Heritage Stealth suffered from significant reliability and build quality issues, including frame warping and slide separation. The Wilson Combat ADP Mark II addresses these flaws with improved machining, ergonomics, and internal components, offering a more refined experience.

Quick Summary

The gas-delayed blowback system, seen in the HK P7 and its clones like the Wilson Combat ADP, uses tapped gas to slow the slide's rearward motion. This allows for a lighter slide and spring compared to straight blowback, but early designs like the Heritage Stealth suffered critical reliability issues.

Frequently Asked Questions

What is a gas-delayed blowback firearm system?

A gas-delayed blowback system, like that in the HK P7, uses gas tapped from the chamber to slow the slide's rearward movement. This allows for a lighter slide and recoil spring compared to traditional straight blowback designs, potentially improving handling and recoil management.

What are the main differences between the Heritage Stealth and Wilson Combat ADP?

The Wilson Combat ADP Mark II significantly improved upon the Heritage Stealth. Key upgrades include a machined slide instead of investment cast, better grip ergonomics, and redesigned internal components for enhanced reliability, addressing critical issues found in the Stealth.

Why did the Heritage Stealth have reliability issues?

The Heritage Stealth suffered from poor build quality and reliability problems, notably heat warping of the polymer frame due to the gas system's operation. Reports also indicated dangerous failures, such as slides detaching from the frame during firing.

Where did the ADP pistol design originate?

The ADP pistol design originated in South Africa, created by Alex Du Plessis in the early 1990s and initially manufactured by Aserma. It was later brought to the US market by Heritage Manufacturing and subsequently refined by Wilson Combat.
