Call Mag-Safe at 1-407-834-9966, they....
are most helpful and courteous. I have called them and they know which guns will handle their products reliably and safely. You might want to read the "Strasbourg Report" , on this ammo. Ed Lovette, author of the book" The snubby revolver" believes in the magsafe ammo for self defense in carry handguns, and uses them in his carry guns. If you want to shoot through glass or a door to hit someone on the other side, this ammo will not be effective for that. Something one must be aware of. It is a niche ammo, in that it was designed for air marshals where excessive penetration would be detrimental. Its strong points is that it is very lethal up-close and recoil is mild.
