So, I am considering trying my hand at Open. I have the opportunity to purchase a used STI Grandmaster with 2x 170mm magazines, 3x 140mm magazines, plus the stock magazine, a CRSpeed WSMII holster, 3x Safariland adjustable roller mag pouches, a 38 Super die set and a few hundred pieces of .38 Super brass for $2600. The gun has had a little tuning done too it, and it runs well. Is this a good deal, an OK deal, a "meh" deal; or should I stay away from the Grandmaster entirely and spend more on a custom gun if I'm at all interested in trying this?
