I have an STI Guardian in 9mm and it's been my primary carry for several years. I can't recommend it highly enough. Very reliable, eats any ammo I've fed it, and is amazingly accurate for a carry size (3.9" barrel) pistol. I've also shot it in IDPA and local league matches. My wife picked up an Escort a few months ago and loves it. At 3" and with the alloy frame it's about 10 ounces lighter than my Guardian. In 9mm both guns are very easy shooters.
