You're not bulletproof...

SRM 1216 (A unique shotgun that somewhat mimics the Kel-Tec KSG with the use of alternating magazine tubes. The major difference here is that the SRM is semi-auto only. Note that there are 32+1 shells pictured but it doesn’t hold that many in one tube. The largest magazine tube available is 16 rounds, of which 2 are pictured hence the 32 shells. Very expensive shotgun, retail is around $2,000+.)
