The French M1892 and 1895 Nagants originated from nearby places and time, so not surprisingly their dimensions are close enough that I ordered in several Nagant holsters that while not an exact match do well enough. Inexpensive surplus Nagant holsters are easy to find on the internet (so not much risk in trying one), and also even found a reproduction left-handed leather one with shoulder strap attachments from 'World War Supply'.
