Hey all. I'm putting together a 9mm AR with an 8.5" barrel and was wondering if I could get some advise on what HD ammo would perform well out of a barrel that length and cycle reliably while giving good terminal ballistics. Thanks for any input!

Can't go wrong with the HST or gold dots.

Does +p matter for a longer barrel?

You might gain an extra 100fps or so.
I carry the 147gr +P

Plan on firing a decent amount of whichever 9x19 you buy.... sometimes the feeding of HP's can be fussy.
