These are all N-frames, listed from oldest to newest:
5" re-blued 1914 First Model 44 Hand Ejector, New Century or the Triple Lock.
1921 2nd Model 44 Hand Ejector with barrel cut to 5".
Re-barreled 4th Model 44 Hand Ejector or 1950 Model 44 Target.
Model 24-3 w/ barrel cut to 5".
Model 624, cut to ~3.5" and round butted.
I constantly argue with myself about which is the better revolver cartridge: 44 Special or 45 ACP. On any given day, either one could win. (smile)
