The boy was asleep so he didn't mind me using the high chair again. I pulled the factory barrel and 2 shot extension off the 870 and installed the Vang Comp barrel. I reused the extended spring. still loads 4 rounds just fine. Just has a few extra coils stuck in the magazine tube. PITA to get it all worked down the tube.
This one is done. Just need to get things wrapped up and my stamp in for the Police Magnum.
