The ejector rod on a 2 inch J frame does not allow for full stroke ejection, nor does a 2.5 inch K frame [in .38 Special or .357 Magnum].
Only barrels of 3 inches or longer have full length ejector rods. My 640 [2 inch barrel] has a cylinder face to end length of 1.25 inches and my 66 [4 inch barrel] has a cylinder face to end length of 2.25 inches [both include the yoke].
The effective stroke length is longer on full sized revolvers versus short barreled revolvers.
