My Russian (Google Translate) is not good, but it appears that Izhmash is manufacturing a carbine version of the Nagant M1895 revolver chambered in .22 LR named the KP-22.
This gun was mentioned in a press release from Izhmash last month (emphasis added)...
Among the new hunting weapon of the delegation were shown small-caliber rifle revolver type "Hawk" and "Falcon" and carbine "Saiga-22", which can be used for entertainment and for training of fire.
The combination of the classic Nagant M1895, the .22 LR cartridge and the retro-but-coming-back-into-fashion carbine revolver concept make for a very nifty combination.
