I was thinking about picking up an SPR94 in .223/12 gauge.

The problem is, I think they got it all wrong in that size. The .22/.410 version has the rifle barrel on top and the shotgun barrel on the bottom. The thumb switch selects which barrel you want to fire.

The .223/12 gauge version has the shotgun barrel on top and the rifle barrel on bottom, and double triggers (yuck!).
