What are the definitions for supoorted and unsupported chambers?
A. A supported chamber means there is no case web visible when the round is seated in the chamber., ala the Tanfoglio, for example. Drop a round in a pulled Glock barrel and take a look at the 6 o’clock position; note that you can see an exposed portion of the case web. Some people are “iffy” over this as if there is a KaBoom! the case will rupture at this point and vent hot hases down the pistol grip, maybe damaging trigger components, blowing the mag out of the gun, or worse, touching off rounds in the mag and between the frame/slide gap. Take a look at the Beretta 92 and you’ll notice the same lack of support. No big deal if you ask me.
