The problem with pistol caliber carbines:
1. Lack of power. Adding barrel length will not make a 9mm into a 223. If you look at actually shootings, the most powerful handgun cartridges don't compare well to even moderately powerful mid range rifle rounds.
2. Lack of penetration and overpenetration. When pistol caliber carbines and SMG started to be adopted by police agencies, one of the rationales was that rifle caliber rounds - in particular 223/5.56 - would overpentrate in urban environments, causing a hazard to bystandards. Actual tests showed 9mm and 40 were actually more likely to present a hazard due to overpenetration. This has been one of the factors that has led to the wide spread adoption of 223 by law enforcement agencies.
If you need penetration, a full power rifle, or intermediate cartridge with the proper ammunition will defeat barricades, vehicles, etc - should this be a requirement.
3. Cost. Unless you are looking at the more inexpensive PCCs - Keltec, Hi-Point - there is generally not much of a price advantage of PCC over rifles.
Basically, a rifle caliber carbine can do everything a PCC can do - and do it all better.
All that being said, the most inexpensive PCCs (Keltec, Hi-Point) are still about $100 less than inexpensive rifle caliber carbines like the Saiga - and well under most American and European military style carbines.
(A quick check on Gunbroker shows a NIB Hi-Point 995TS for $250 and Saiga 7.62x39 16.5bbl for $350)
