I bought some Winchester Ranger T ammo, 115gr +P+ a while ago, it's my carry stuff and have shot a box or two through the gun with no problems. The 'pigtail' has been gone since I first bought the gun, I'm probably close to 2K through it including +P occasionally, never a problem. BTW, the +P+ Ranger Ts WILL go through both sides of a Ford Aerostar van, I got to find that out during a weekend class that included carjacking scenarios, at the end of the class, just fer grins, we got to 'test' different ammos on the car, handguns, rifles, shot guns, yeah, it was FUN!
