Holster for the S&W MP-12

Hey, it's a 12 gauge shotgun with a pistol length barrel, pistol grip, and a 12rd drum mag. It's the perfect home defense gun, and I need to keep it in my nightstand.<br><br>Unfortunately, S&W doesn't sell any holsters for it, and I've tried a few other holsters designed for other 12 gauge shotguns. It's basically impossible to find one that will fit the drum mag.<br><br>I've tried the Gearwrench pistol holsters, and they work fine. I've tried the MOLLE attachment, and I've even tried the drum mag attachment which also fit fine.<br><br>I'd love to hear about other holsters for this particular gun, or if anyone else has had any luck with other brands.<br><br>&#x200B;
