Hello. The high velocity, lightweight, but standard pressure Aguilla .45 ACP was reasonably accurate, but had one heck of a loud muzzle blast! It felt about like shooting a .38 Super from a 1911, ie pleasent. The hollowpoint round would feed OK in both a Kimber and a Les Baer that were both reliable with both standard ball, numerous standard pressure JHPs, and Plus P ammo. However, this stuff would result in the slide stops prematurely locking back in both of these 1911s. Shooting that bullet into mud at the range (not too scientific, huh?) showed that the bullet does split into three pieces. Groups at 25 yards are about 3" from either the Kimber or the Baer. Best.
