Lots of good advice here.

My rule of thumb is I don't clean my guns unless they are going back in the safe. (And I keep them in the safe.) The most I've shot through a single gun without cleaning is 500 rounds over a two day pistol class. I was shooting Winchester white box 9mm our of my G17 and had zero problems.

A friend in class shooting his Sig did have some problems with some reloads he'd done (on my press) because they wouldn't reliably cycle his gun (they would cycle mine fine).

Keep in mind that your gun will actually get more accurate after the first 10-50 shots. The theory I've heard is that a little fouling in the barrel actually provides for a better gas seal. (The carbon will fill in the low spots.)

If you're going through 5,000 rounds of quality ammo through a single firearm in a day, your biggest concern is the heat, not the fouling. If your going through 1,000 rounds of crappy Russian stuff with corrosive primers in a day, then yes, you need to clean a few times.

It sounds like you're well within the operating bounds of the gun though. Have fun!
