Just my opinion...
You seem to prefer the revolver, so my thought would be to practice with it until you can shoot it as well as, or maybe even better than, the semi-auto. Or at least to a reasonable standard of accuracy/precision.
Of course, that also depends on how much of a difference there is between shooting the semi-auto and the revolver. If by "better" you mean can get 2" groups with the 3913 vs 3" groups with the 36 at the same distance, I wouldn't worry about it. If you can get quick center-of-mass hits at 7 yards with the 3913 but can't hit the broad side of a barn at 3 paces with the 36, that's another matter entirely.
