Hello, fellow Carolina Glockers! I'm in the Piedmont Triad, Alamance County, and I'm heading down to Salisbury (NC) mid-week for a three-day course of instruction for my NC Armed Security Guard certification. The course of fire requires 300 rounds. I'm running a Gen 2 G17 (9mm), and I was looking for some recommendations on where/what to purchase in bulk? Obviously, I'm looking for ball ammo. Walmart has an alright price; but, I'd prefer to use them as a last resort. Any thoughts? Thank you. And, be well.
