"This 9mm load is rated at +P pressures (not +P+) and as such is safe to use in any/all 9mm chambered pistols that are in normal operating condition. The hard cast bullet (not lead but hard cast) will not lead foul a functional barrel that is in a normal state of operation including polygonal barrels in any make of pistol including Glock pistols. It may be helpful to read my essay on ""Hard Cast Bullets in Polygonal barrels"".
Many encounters with wild animals and the human criminal element will happen in low light and for that reason we've utilized a flash retarded powder in this load. There is no need to be blinded by your own gunfire at the very moment of need when protecting yourself or loved ones.
This load is designed to penetrate deep (4 to 6 feet) in a straight line through flesh and bones and that flat nose does considerably more terminal damage as it crushes its way through tissues than a round nose bullet does as it slips and slides it way through tissues and that crushing action keeps the bullet nose forward and ensures very deep straight-line penetration. Round nose bullets tend to get sideways as they slip and slide through tissues and this often causes them to veer off path. This bullet is designed to crush through a large bear skull coming and going.
While this bullet will over-penetrate humans even 300+lb humans wearing heavy winter coats there is nothing wrong with using it for defense against humans in situations where over-penetration is not a liability__..sometimes over-penetration is desirable if we need to shoot through car doors windshields stick frame walls or any other soft cover in stopping a threat.
