Looks like a 44 Winchester caliber Frontier model Double Action to me.
The difference between a 44 Russian and a 44 WCF is HUGE.
The case width alone at the head is comparing a 45 cal to a 44 cal. See photos of case specs.
It’s not safe to attempt to discharge a 44 Russian cartridge in the chamber of a 44 WCF. Grossly undersized case with oversized bullet up to .432 depending. That’s as mush as 5 thousandth’s over sized!!

Plus, Target sights on a 44 Frontier does in no way compliment the caliber. The 44 WCF is “not a target caliber”on a pistol platform. I wouldn’t even call it target worthy on a rifle platform.

It’s a general purpose caliber at best. In fact I am not aware of any target pistols in that caliber during the “ Antique” black powder ERA. The reason is obvious.

If you’re in Canada with a 44/40? Opps!!!
