Most manuals recommend .750.
I don't bother to trim mine. Never had an issue with length.
If they act similar to 45ACP brass, they will shorten as they are fired over time.
I just load them all , But I do use a load in the low to mid of the loads in the book
So I am never close to max
Unless I wanted to do Match shooting
I just load the mixed brass all the same OAL
Some have a bit extra of the bullet inside or outside of the case
But they all go bang
LOL I messed up and loaded some 380 ACP with 9 MM powder charge and bullets
I just had REAL long 380 ACP loads
Even these short cased loads shot fine out of my Glock 17
So IMO case length isn't a big deal

I’ve never trimmed 9mm in my life! Just load em
Long, Wide, Deep, and Without Hesitation!
Agree with previous posts, load em and shoot em.
Case trimming is more for rifle cartridges. Never trimmed a handgun case ever.
I taper crimp, and have yet to trim any 9mm or .45ACP.
I haven't had a problem so far.

OK People. Enough of this idle chit-chat.
This ain't your Grandma's sewing circle.
EVERYONE!
Back to your oars. The Captain wants to waterski.
I have done that a few times. Went ahead and fired them with the rest of the 9mm. The pistols never noticed the difference.Originally Posted by Johnch
I taper crimp, and have never needed to trim any 9mm, .40 S&W or .45ACP.
thanks, that will save me a lot of work!
Never heard of 9mm extending. Just load them up and forget the trimming.
