DoubleTap Defense pocket pistol didn’t get a lot of love in our latest grab-off competition with the Kahr PM9. It might have something to do with the masochistic pleasures of firing the .45 derringer. As Jeremy S. pointed out in his three-star review of the DoubleTap, shooting the entry-level .45 caliber version is a bit like shaking hands with a sea anemone. Diehard DoubleTap fans can solve the problem in two ways: buy the ported .45 or the the 9mm version (ported or non-ported). But what if you’ve already bought the non-ported .45? Simple! Just warm-up the plastic and buy a conversion kit. DoubleTap would be happy to send you a nine-millimeter barrel for $199 or a ported .45 upper for $269. And if you’re still hurtin’ for certain DoubleTap Defense is working on a slip-on oversize rubber grip that fits all DoubleTaps. The website says it will offer “Soft touch for inproved comfort” [sic] and “Improved shock absorbtion to reduce muscle fatigue” [sic]. Done!
