That is why I support 7.62x25 if you want a cheap to feed carbine that is still pretty snappy.
I second this as well. 7.62x25 and 10mm are what I want. 40 is exactly what it is followed by "short and weak".
I believe a tokarev magazine AR is being considered.
Nothing like shooting expensive 10mm factory ammo from an expensive restricted firearm.
The only reason to shoot a pistol carbine would be to reduce cost, not compound it.
A .40 cal would be the best choice. As long as it takes pistol mags.
Then everyone who shoots idpa or ipsc has a common caliber to work with.

A gun capable of taking glock mags in the standard glock calibers.
9mm, 40, 45, maybe go with some of the other mentioned calibers too.
.45 is a great round for a carbine, especially if you have pistol mags so they can have 10 rounds![]()
Kel Tec - version takes glock mags. RCMP Say NO!

Its probably because the thing folds up like that. They have a lot of stupid laws, (and stupid people making them) so im sure they would have found an excuse to not let it in, ALA the 40mm grenade training rounds and such. (kept messing with it till they got what they wanted)
