Quick question. I read in the rule book that compensator or compensated barrel is illegal. Now does this apply if the gun came from factory already compensated (like glock 17 C) without extrenal compensating device? I have the tisas zigana sport on the way to local ffl. To be fair, I bought the gun to be a fun range toy. I have a defensive pistol that i have on my bedside. I don't want to put a lot of wear and tear on that pistol (PT92).
