The Masterpiece Arms DS9 Comp Open is the ultimate 9mm race gun, purpose-built for dominating the IPSC and USPSA Open Divisions. Designed with input from Team MPA champions David Lyell and Travis Tomasie, this pistol combines precision engineering with competition-specific features to deliver unmatched accuracy, speed, and reliability on the course.

Key performance highlights include a custom-designed 3-port compensator for reduced muzzle rise and faster follow-up shots, an MPA-designed optics mount with an integrated thumb rest for improved control, and a competition-tuned trigger with a crisp 2.0 lb pull. Its aggressively textured 17-4 stainless steel grip ensures superior handling, while the high-ride shielded ambidextrous thumb safety provides intuitive operation.

This pistol features a hand-fitted 5" 416R stainless steel barrel with custom porting for enhanced performance with 9mm Major power factor ammunition. The frame and slide are meticulously hand-lapped for a flawless fit, and the included competition magwell accommodates both 141mm and 171mm MBX Extreme magazines for rapid reloads.

Every component of the DS9 Comp Open is machined in the USA from premium materials, ensuring exceptional quality and durability. With its lifetime warranty and competition-ready design, the MPA DS9 Comp Open is a powerhouse for professional shooters who demand the best.

The recommended ammunition for the Masterpiece Arms DS9 Comp Open pistol is specifically tailored to maximize its performance in competition settings. This custom 9mm Major load is developed with precision specifications that ensure optimal cycling and ballistic consistency. It features a 124/125-grain projectile, paired with 9.8 grains of Accurate No. 7 powder, and is loaded to an overall length of 1.180 inches. Using a small pistol magnum or small rifle primer, this ammunition produces a power factor of 171-172, delivering the energy and recoil dynamics required for high-level competition.

Important Note: This 9mm Major load is designed exclusively for use in the DS9 Comp Open and other competition pistols rated for Major power factor. It should never be used in standard firearms, as its higher pressure can exceed the safe operational limits of other guns. Always adhere to manufacturer guidelines and verify your pistol’s capability before using custom or high-pressure loads.
