Most pistol brass is straight walled, so it shouldn't make any difference. I normally check length after sizing straight walled brass and always after sizing bottle necked brass.
No, he asked when to trim, before or after sizing. That is the answer. After.
I never trim auto brass, but I do trim a lot of revolver brass. I am shooting mixed .38 Spl and .357 brass, and the lengths are all over the place, so I trim them to get better more consistent crimps. I bought a bunch of Starline .32 Long and .32 Mag brass. It is so consistent in length I have not trimmed it. My .45 Colt brass is also mixed, and I trimmed it as well.
Many people never trim any pistol brass, and I never knock anyone for not doing so. YMMV
Trim after resizing. And for the record, I trim all my brass. There is a SAAMI specification for "trim too length", use that specified length. And your right, it does make crimping go a lot more consistent and helps to eliminate issues with light, or over crimped cases, which leads bullet jump, or buckled cases.
