STI Trojan in 9mm. The break (4lbs.) is so crisp and clean it surprises you, but that's one of the things STI is known for. I own a number of production hanguns (Ruger, Tangfolio, Beretta, CZ, Taurus, and Remington Rand) and have been able to shoot quite a few rounds with others (Kimbers, Glocks, and Colts) and none compare to STI.
