Barnes has long been known for their solid copper rifle bullets with a well-established reputation in the hunting fields. Something that may not be as well known to some is their line of defensive ammo. This Barnes 9mm load is labeled as +P but the velocity seemed a little low in my sample. This ammo was shot using a Sig P229 with a 3.9-inch barrel. Shot into two 16 inch blocks of Clear Ballistics gel. Two round into bare gel than two rounds into gel covered with heavy clothing and then finally two rounds out of an M&P Shield with a 3.1-inch barrel.
The first round into the bare gel had a velocity of 1047fps, penetrated to 13.5 inches and expanded to .68 inches. Round number two penetrated to 13.25 inches, expanded to .69 inches and had a velocity of 1067fps.
The first shot into the heavy clothing gel did not register on the chronograph but penetrated to 12.5 inches and expanded to .70 inches. The second round also expanded to .70 inches, penetrated to 13 inches with a velocity of 1048fps.
The velocity out of the Shield dropped a bit with the first shot coming in at 997fps, penetrated to 12.5 inches and opened up to .69 inches. The second round also penetrated to 12.5 inches with a velocity of 980fps and expanded to .70 inches.
