Weatherby's SA-459 TR is a dependable semi-auto shotgun designed specifically for home defense. The SA-459 has a gas-operated semi-auto action that reduces felt recoil. It features a trimmer forend for easy handling and an oversized hourglass bolt handle that's easy to locate and operate. The PA-459 has an 18-1/2" chrome-lined barrel with a removable extended ported cylinder choke tube that gives it an overall length of 20". The 459's shorter length of pull and comfortable, ergonomic buttstock with rubber textured grip areas allow for snag-free shouldering. The M16-style front sight has a fiber-optic pin that affords faster target acquisition and the clamp-style rear LPA-style ghost ring sight is easily adjustable for windage and elevation. A Picatinny mounting rail, an extended and enlarged slide release, and a set of sling swivel studs all come standard.
