Pricey but very good quality guns. I have fired the sub-compact 9mm and 40 cal models a bit. They are not any different than most other sub-compacts as far as I can tell. They are Kel-Tecs main rival in this field.
I have only fired the compact in 9mm. It had the polymer frame, and was way to poppy for my taste. Having said that, I like my guns to be range shootable, and I have big hands. was just hard to get a quick follow shot up for me. I have looked at the tactical a couple of times, but wouldn't buy one without shooting it first... The metal frame guns appear to be very well machined and finished.
