This thread has reminded me I have a HW45 with the original walnut stock and wider foresight somewhere. I'll need to dig it out one of these days as I've not shot it in years. From memory, the barrel was threaded for a silencer and it was difficult to focus on the rearsight when using the stock. Probably why it has not been used!

Currently looking for Baikal Makarov pistols with the following prefixes to the serial number: 98, T01, T09, T21, T22
Prefer boxed or cased but will consider loose examples too.
