Stan Chen founded ASYM Precision Ammunition in 2010 and built it into a championship brand—ASYM ammo won 8 world and national titles, including the 2013 NRA National Pistol Championship at Camp Perry. In 2014, he sold ASYM to focus entirely on custom pistolsmithing, his core professional passion.

"I want to be there for their soccer games, violin/cello/guitar recitals and mountain bike races. Not to mention what my wife Kristen has tolerated with my work hours!" — Stan Chen, explaining his decision to refocus on custom builds

That deliberate choice to narrow focus means longer wait times but uncompromised quality. Stan personally trains new personnel on any contracted work and maintains direct control over every detail.

The Chen Custom family competes seriously in IDPA (International Defensive Pistol Association). Stan and his daughter Libby have both taken first place in their divisions at Rocky Mountain Regional IDPA Championships. They sponsor matches and are active in the competitive shooting community—recent events include the Third Rock IDPA Championship at Cameo Shooting and Education Complex (near Grand Junction) and the Wyoming Governor's Match in Casper.

Stan's approach to 1911 customization focuses on:

• •Performance - Action smoothness, reliability, shot placement
• •Ergonomics - Controls positioned for fast manipulation
• •Precision fit - Tight tolerances throughout
• •Artistry - Detailed finishes and checkering as functional art
