Kel-Tec is taken fairly serious by firearms enthusiasts as a manufacturer of low-priced but functional firearms. They’re probably best known for the compact 9mm P-11, a popular off-duty choice for law enforcement officers and other concealed carry applications. Its smaller cousin the .32 caliber P-32 also gets some play for its extreme small size. Their long guns haven’t proved as popular over the years, though their new(ish) bullpup-configuration carbine the RFB looks reasonably interesting if you’re into that sort of thing.
The newest Kel-Tec offering causing a bit of a buzz seems to support my observations about a move toward the adoption of lower-caliber rounds that allow for a very high capacity magazines, as with the FN Five-seveN. It’s the forthcoming Kel-Tec PMR-30, a full-sized semi-automatic intended as a plinker or target pistol, but potentially powerful enough to serve as a grab-and-go gun in case the zombies and/or invading space aliens start flooding down your street.
