Frequently Asked Questions

What is the most unique feature of the Kel-Tec PR57 pistol?

The Kel-Tec PR57's most distinctive feature is its internal 20-round magazine, which is loaded using a proprietary stripper clip fed through the top of the slide, rather than a traditional removable box magazine.

How much does the Kel-Tec PR57 weigh?

The Kel-Tec PR57 is exceptionally lightweight, weighing 13.9 ounces when empty. When fully loaded with 20 rounds of 40-grain ammunition, it weighs approximately 18.9 ounces.

What type of trigger does the Kel-Tec PR57 have?

The PR57 features a Double Action Only (DAO) trigger. A key characteristic is its lack of second-strike capability; if a round fails to fire, the slide must be manually cycled to reset the hammer.
