“Glock has teased the factory beavertail backstrap since we first saw it in 2011. It’s finally out in the open with the introduction of the updated Gen4 Beavertail Modular Backstrap Replacement kit.
“I’ve been shooting my G19 with the Glock beavertail for a few months. While a beavertail is traditionally used to protect beefy hands from slide bite, Glock’s slide-on beavertail does a little more. It adds a tiny amount of girth to the top of the grip since it covers the existing grip tail. It’s a very subtle change that hasn’t had an obvious effect on the pistol’s point of aim. But, the lowered backstrap tail offers the equivalent of a slightly higher grip for better recoil control whether you have chunky or regular sized paws.
“The updated Glock backstrap kit includes new 2mm and 4mm beavertail backstraps, the familiar 2mm and 4mm standard backstraps, a trigger housing pin and a new multifunction clip that has a built-in polymer pin punch suited to backstrap changes.”
