I have always been fond of carbines. The PC9 was conceived with LE sales in mind. The market wasn't there so Ruger discontinued it. In this day and age ARs in 5.56/223 are all the rage in LE circles and fears of over penetration by these rounds have not materialized negating the pistol caliber carbine concept. I like pistol caliber carbines: I have a Model 94 Winchester Trapperin Model in 45 LC, a CX4 in 45 ACP, a Plainfield M1 Carbine (arguably the best civilian marketed one) in 30 Carbine which approximates a .357 Mag hot load and I just picked up a Hi Point 9mm in a group buy. I like the idea of interoperability of pistol and rifle ammo like the 1873 Winchester and The Colt Single Action Army in 44-40. If Ruger has continued with the PC9 I would have purchased eventually but they did not. I recommend that you want a 9mm carbine depending on your wallet, you need to look at Hi Point or Beretta.
