The Standard Manufacturing SP-12 Compact is the shorter, more maneuverable version of the SP-12. All of the AR style controls of this shotgun are able to be accessed equally from either side of the shotgun, making the SP-12 the only truly ambidextrous compact pump action shotgun available. Shells are fed and ejected through the bottom of the receiver, and thanks to the SP-12 Compact's 3" chamber, it can accept 3" shells, 2-3/4" shells, and even the increasingly popular 1-3/4" miniature shotshells.
