Cx4
The CX4 was first offered as a "LEO" weapon. I suppose the thinking was as police departments already had the "92"s that this would be a good fit. They do make different magazine adaptors for them too. My understanding was that the Ruger PC9 and PC40 carbine was made with the same thinking. (PC=police carbine) The pistol caliber carbines make great little rifles for plinking too.
I have both a High Point 9mm carbine (bargin for the money) and a CX4. When I take them to the range folks really enjoy trying them out. They shoot very straight, don't wear you out, and are economical--and fun--to shoot.
