Pistol brass need trimming?

[Davemac]

Getting started in pistol reloading mostly will be 9mm , I've heard that pistol brass usually doesn't need trimming? Unless just trimming to uniform different brands head stamps? Thanks

Never trimmed a pistol case

Just rifle

If your loading bottleneck like 357 Sig maybe but not straightwall

There's a spec naturally. But hell no.

Trimming brass to be used for revolver rounds can be beneficial, especially those with heavy recoil, as it helps to ensure the crimp is applied evenly around the crimp groove and at the proper location. For semi auto use such as 9mm, though, I wouldn't worry about it.

I've done it only a few times for revolver brass that's used for my hotter loads. It ensures a consistent roll crimp.

For typical use, no. If in was trying to win a bullseye competition, maybe, but probably not even then.

Or perhaps long-range revolver work. I recycle any piece of handgun brass that fails to please me, or requires any special handling, like trimming.
