One little glitch: Yes, you have four "38/44" revolvers----BUT only one of them is for the 38/44 Cartridge. That would be the NM #3. The other three are for the 38-44 cartridge. HUH?!!
The 38/44 cartridge is a 19th century BLACK POWDER creation with a case the same length as the cylinder (1 7/16") and with the bullet seated entirely within the case---unless it's a later gun with the longer cylinder. Given the original, that makes for ZERO throat, which makes for VASTLY improved accuracy. It came in two versions, a 146 grain bullet in front of 20 grains of powder, and the gallery load of a 70 grain bullet (round ball) with 6 grains of powder. Legend has it Ira Paine (who designed the cartridge) set records for accuracy yet to be broken.
Okay, the 38-44 is an ENTIRELY different cat!! It's a hot-rod .38 Special cartridge. "Hot-Rod" as used here, refers to one of several different loads, this one pushing a 180 grain bullet out the front at 1160 fps---the regular 158 grain round nose at 1200 and some odd fps. Bottom Line: It's a 20th century smokeless powder cartridge which gave birth to the 357 Magnum, and assuming it'll fit in your NM #3 (and it will), it will very likely blow it to smithereens; and HURT YOU-----BAD!!!!
The moral of this story is there are two different so-called 38 (- or /) 44's, and they are DIFFERENT!!!! And as to which is a - or a /, I'm sitting here with my N&J book totally confused, because it's going back and forth between the two like it doesn't make any difference--and IT DOES!!
BEWARE OF THE DIFFERENCE!
