I don't have any experience with the loaded ammo but the bullets themselves are available on midway in 9mm under the sierra custom label. They have performed very well in my sr9c and based on what I recover from the ground show good expansion in soft soil.
HoHumm-I need to stop reading ammo tests! The 2 foremost ammo testers-"Shooting the Bull" and "Tnoutdoors" found the ammo to be erratic and inconsistent. In 1 instance penetration was only 7" with a 4" glock 19 and 30" with 3" short barreled pistols.
I guess I'll stick with gold dot 124 grain +p's for short barrels. 35,000 NYC police and 250,000 French officials use this load. I like +p loads for my cz75 compact knockoff. With a short barrel it needs all the help I can give it!!
