I've never trimmed a 9mmP case....

I've probably loaded 25,000 9mm rounds as it is the caliber that I shoot the most, and I've never trimmed a case. I do segregate the cases by manufacturer. Does not trimming make for inaccurate loads? I don't think so. My standard loads will shoot 5 shot 25 yard groups of 3/4" or less out of my Browning Hi-Power GP Comp, and my Sig 226's will do 1.5" 5 shot groups at 25 yards (not just one Sig 226, but all 3 of mine will do that...), and for that matter, so will my standard Hi-Powers...... My Luger pistols will function reliably with my handloads (sometimes an iffy thing with a luger) and shoot groups that run around 1 inch if I can manage their so so triggers OK.

In my experience, more important is overall loaded length. Too many loading manuals and handloaders keep the overall length of their 9mm rounds on the short side, and I've found that most 9mm handguns shoot better with ammo loaded out to the max. end of overall loaded length.....

Just my experience....
