THE REST OF THE HOLSTERS ARE FOR REVOLVERS. So don’t list anything that references a “mag pouch” in the carry choices. Only available in regular belt, chest, regular shoulder and thigh. Revolvers do not fit ankle or belly band, which is worth noting, but as long as it is not a drop down option it should suffice.
