I define "train" to be when I am actually running movement drills, magazine changes (one and two handed), malfunction clearances (one and two handed), one handed shooting, weak handed shooting; the whole 9 yards.
That being my definition, I get to train like that about 12 times per year with live ammo. Magazine changes are fairly easy to practice without live ammunition, but you cannot practice malfunctions without putting live rounds downrange.
I train in weapon retention about twice per year, and knife fighting about 2-3 times per year.
All in all, your 2,000 rounds is quite a small amount. I got my M&P9 for this past Christmas and already have about 2,500 rounds through it. Even my 2,500 rounds is a very low round count for a handgun.
