There is a propensity with gun nuts to downplay the value of a pistol caliber carbine.
For those of you who don't know, a pistol caliber carbine (PCC) is a rifle that fires a lower powered round that is typically associated with a pistol. For example, a .357 fired out of a lever action rifle. The extra barrel length gives the gas a longer time to expand, creating higher velocities, increased accuracy, lower bullet drop over a distance.
A lot of gun nuts consider the PCC to be an intermediate, and therefore pointless, long arm. They say that a pistol round is better out of a long arm, but not as good as a rifle round out of a long arm. "If you're going to carry a rifle, why shoot less effective rounds?" Technically, and ballistically, they are correct. A rifle round is almost always better than a pistol round out of a rifle, that's what they were designed for. However, a pistol round is far more efficient, with less kick, and more accuracy out of a longer barrel.
It's my opinion that those gun nuts are being a short sighted (no pun intended). I love the idea of the intermediate firearm. Kind of like the scout rifle concept, the idea that a firearm can be used adequately for multiple purposes really appeals to me. A PCC is a good example of this.
If you want a long range hunting rifle, there are plenty of long range hunting rifles out there, but they are exactly long range hunting rifles. Not much good at anything else.
Just like a hand gun for personal defense, they are designed for their purpose specifically. Not much good for accurate distance shooting.
Gun nuts want a rifle that is exceptional, a general purpose firearm is almost by definition average... but it's average at a lot of things, an expert at none. Personally, I like the idea of a firearm that can be used for multiple purposes over carrying multiple firearms that each have a specialty.
There are quite a few PCC options out there. I lean toward lever actions, there are plenty of good revolver/rifle combos out there. .22lr, .357, .44 mag, .45lc... Historically, cowboys liked having a long gun and a pistol that used the same ammunition, that way they only had to carry one. So, cowboy combos are easily adapter to a pistol-rifle combo.
However, in this modern age, there are quite a few options for semi-auto rifle and pistol combinations. With a little research, it's quite possible that your favorite mag fed semi-auto pistol has an equivalent carbine.
If you like Glock, there is a Hi-point carbine for you.
If you like Beretta, there is a Beretta CX4 storm for you.
Even the M1 carbine, which shoots ".30 carbine", has a Ruger revolver that uses the same round.
Almost all of the big gun manufacturers have a PCC available, that uses their variety of magazine and ammunition. It's only too bad that there isn't a good PCC that will take a large variety of magazines, it would make acquiring and matching magazines so much easier. Personally, I like Glocks but want a CX4... those magazines don't match up.
Or you could look at something like Mech Tech where you can convert your favorite pistol into a PCC. This is of course depending on your local laws. There are a couple of companies that offer packages like this, it's an interesting option.
The other benefit is the range time fun... They're a blast to shoot, very low recoil, and pistol ammo is usually far cheaper than rifle rounds. For a box of common ammo it is around the same price, around $25, but rifle rounds usually come in a box of 20, pistol rounds usually come in a box of 50.
The PCC might not be the best at anything, but it will get the job done in most situations. That's what I like about them.
Right now, it might be the M&P 22 and the M&P 15 combo. Or I could do the Rossi R92 and the Ruger Blackhawk. Neither option is too shabby, if you ask me.
