as far as being exc quality, dependable, reliable expanding hollow points, the Hornady's have equals, the Speer Gold Dot is one.........but as far as I know, nothing is better that they are as a projectile......... now whether or not does the ammo work without a hitch in your particular semi auto/ or select fire weapon? Like any other ammo that is to be used as self defense/duty loads.... it must be tested extensively in your own weapon to make sure.............I always ran a minimum of two 50 round boxes through any of my semi-auto handguns, before I'd use them as duty loads.........

one of the true assets of a good revolver as a duty gun, is that they will almost always reliably work will all good ammo......... unless the primers are too hard & the hammer throw is too light........a rare occurrence, but it does happen.
