I've never trimmed revolver/pistol brass. Not even that, which is shot in my carbines. Most of the time, I don't even bother to separate headstamps, especially for 38 Special. Can't say that I ever taper crimped 38 Special, either. I don't compete with 38's , so I'm not after MOA belly gun ammo. I roll crimp almost all revolver loads and taper crimp the semi's. Exception, is the one example, given in a prior post.
That being said, there is usually enough leeway, in the crimp groove to absorb the small variations in brass length. For the occasional short brass, it will become apparent if you crimp in a separate operation. Just set them aside and adjust the seating die to seat them a tad deeper, before applying the crimp.
Most Hornady pistol brass is short, IME. I just toss them in the scrap.
