Well, I'm stumped I've never heard of the CSE line and the ad they're running doesn't help explain anything. If I'm reading the ad correctly the CSE is a compact size that comes chambered in .45, 9mm and .380.
Kimber CSE pistols will also be for sale, saving $100 off the normal ticket price of $650 to $900. Kimber is often known for their reliability and performance, and with the CSE models, nothing different can be said. Offering selections in the popular 9mm, .45 Auto, and .380 Auto chamberings, there is something for every shooter in the somewhat compact, 7+1 design.
