I was reading some info on the 357Sig cartridge that said Glock uses a fully supported chamber in their 357Sig pistols. Is that true and does it apply to all the Glock models?

A. No. No Glock, or any other handgun that uses the modified Browning action, has a fully supported chamber. Some chambers are more fully supported than others, however. The Glock 357Sig chamber is more fully supported than the Glock .40 S&W chamber. It’s more fully supported than the G-19 chamber, and probably as well supported as the G-17 (I haven’t seen one, so I don’t know for sure). The Glock .45 ACP and .40 S&W have the least supported chambers of all the Glock models.
