I'm not sure if the Browning .22 1911s are actual 1911s, they may just look like 1911s and function like other .22 pistols that simply look like 1911s. (e.g. ATI 1911 .22lr pistol.)
In regards to the OP's question, I don't recall any large handgun manufacturers, not already listed, that don't make a 1911.
