Has anyone adopted this round? Does it really serve a purpose? There are only 3 different types of ammo for it that I know of. I know its supposed to have great ballistics. This reminds me of the 5.7x28mm. There are like 2 kinds of ammo for it and maybe 5 platforms. The Five seveN, an AR upper conversion, and the rifle (P90? PS90?) I know one is full auto and one semi. Anyway I think the round is superb but its popularity has suffered because of lack of market attention. I heard it was some sort of a patent stronghold that kept anyone else from delving into the 5.7 market. A revolver would be sweet. A light bolt action rifle would be sweet. But I digress, Won't the 327 share this fate if some more ammo variety doesnt come along? Has S&W recognized this round yet? All I know of is a Charter arms or a Ruger SP101/GP100. How about a Lever Action? How about a J Frame. How about some Golden Sabers or some Ranger T Series? Silver Tips? I realize by the way that the 5.7x28 is immensly popular worldwide, just slightly out of reach of the lay man. I was comparing because its a niche round.
