STI makes very nice pistols, much higher end than a Kimber (and I love Kimbers). They were largely competition grade pistols until the owner retired and sold the company to it's employees. They have tried (successfully) to get in to the consumer/LEO market with pistols geared more to those markets.
The Trojan is totally built in their Texas factory, while the slightly more budget model Spartan is made in the Philippines, and then sent to Texas for final QA and tuning.
STI for years was the "IT" company when it came to IPSC race guns.
A gun is like a parachute: If you need one and don't have one, you won't be needing one again.
