Case gauge for 38sp

Since it's a rimmed cartridge, do I need a case gauge for a 38?  Perhaps instead, just the "ammo checker" gauge?

Also, I shoot regular and W/C 38 from a .357 cylinder, and load 357 once in a while.  In that case, if I purchased the 357 gauge, I would think again , being rimmed, that the 38 would still work.   or...by both?  For my other ammo I've been happy with the tri-level Shooter's Box gauges.

Thanks

I never had, or used one for revolver. Either they fit, or the don't. Your cylinder is the gauge. Check a few when you start reloading and you're good. The brass is never too long

If the brass was longer, would this not affect the crimp?

Pistol brass does not tend to "grow" like rifle brass, which always needs trimming after firing. I've never trimmed a pistol case in over 40 years of reloading. Having said that, if you taper, rather than roll crimp, that solves the "problem".
