The question: is this the accessory you’ve always wished someone would come up with or one of the greatest WTF items in firearms history? RADETEC will introduce two models at SHOT next week, one with a digital counter and – for the numerically challenged among us – a color-coded version that changes from blue to green to red as your available round count drops. Our friends at guns.com say it’s designed “to help train shooters improve their internal ability to count rounds, anticipate reloads, and get back into the game faster.” It could be argued that taking your eye off the target and tilting the gun to check your round count might slow you down a tad, too. But that’s just me. The first models will fit 1911s as well as Glocks, Berettas and S&W M&Ps. Not that the march of technology is without its costs. If Harry Callahan had one for his .44 revolver, we might have been deprived of an iconic movie scene and a highly quotable quote.
