I was just taking to my brother today, he recently purchased the new Ruger 9mm carbine and just got out to shoot it a few days ago. Seems like there's quite a lot of interest in pistol caliber carbines in the market now with offerings from Hi Point, Ruger, Beretta and a host of others. So, the question i ask, why no resurgence in popularity of the M1 Carbine? It's a proven platform, locked breech, soft shooter that packs a heavier punch than 9mm. I've seen several threads here and on other sites wanting a PCC in more effective calibers, like 10mm....so why not 30 carbine?
