Starline Brass STAR45A+PEUP Handgun 45 ACP +P Unprimed Brass 50 Per Bag

The 45 Auto+P is a strengthened version of the 45 Auto with the same external dimensions. A thicker web and heavier sidewall at base strengthens the case in potentially unsupported areas. This case has approximately 2 grains less internal water capacity than the standard 45 Auto.
