To put a finer point on it, you can get away with not trimming pistol cases if they're already under trim-to length (most cases are short). For practice ammo, this is fine. If you want to watch your groups really tighten up, having a consistent trim-to length, i.e. consistent crimp, will change your perspective.
good idea setting mic to full length. i finally have a use for the lock screw. i always open and close it on each case. that extra two seconds adds up over 500 cases
I use a case length gauge the same way for general target practice rounds.

works great i find for general reloading, but for tartet loads ill trim all the brass to the one length, consistance = accuracy

I am using a Lee Factory Crimp die, so it does not matter for the crimp if the cases are the same length or not.
