Shoot them all
The PPS from an IWB will be fine. You'll probably need two spare magazines.
Round count for the September match will be around 60.
It will be held at Heartland Outdoors on Kelly, just north of Danforth in Edmond on the 3rd Sunday of the month. In this case, September 19th.
Cost is $20, but you're eligible for a $50 gift certificate after the match. (must be present to win)
Looks like I shoudl be able to make it to the September match. I can help out with scoring/ROing again if I'm needed.
