Ya know.. one think I like about this gun, besides being so ugly only a mother could love it.. is that it does carry short... compress the stock and it's fairly compact. I've been thinking about a long barreled truck gun for a variety of work reasons. I've considered my 500, buying something like a KSG or even a O/U coach gun, then lately I've been hot on building a .300 AR pistol. These are in addition to my EDC, which is typically an XDS45 or a SIG P320C. But I've always thought the SPX is compact enough to keep in a vehicle and even though it's 6 rds with even Federal 170gr at 2200 fps and 1800+ ft lbs... its a blunt force trauma gun for sure. Hornady's 160gr STX is hot enough to hit 2400 fps and 2046 ft lbs which makes for a devastating round. Other than simple backup though when will one really want a truck gun? Maybe a situation involving vehicles or larger barriers that you need to pound on?
