The Standard Model incorporates the features many of our owners want most in their defensive shotguns in a value-packed package. The 18" cylinder-bore barrel with 3" magnum chamber will handle your ammunition of choice - and the included magazine extension tube offers increased capacity for a total of 7 rounds. Wilson Combat includes an extra-power heavy-duty stainless magazine spring for sure shell feeding in any situation and a high-visibility non-binding follower to indicate an empty-magazine tube at a glance. The Standard Model also includes a receiver-mounted Sidesaddle shell carrier - in a critical re-load situation your extra ammo is quickly available in a no fumbling load-by-feel manner.
