Pistol caliber carbines are a good choice if you want a nice gun to plink with, hunt small game with, and trek with outdoors. Currently, there are multiple choices for pistol caliber carbines, with some being extremely cheap, and some being ludicrously expensive.
Carbines (Pictures Soon)Edit
Calibers: 9x19, .40 S&W, .357 SIG, .45 ACP
-Takes Glock Magazines
-Caliber Conversion Kits Available
-Takedown Versions Availbale
Price: 760-900 USD
Note: These currently are the go to Pistol Caliber Carbine right now. there aren't many issues with these, however they don't have any plans to make them in 10mm.
Calibers: 9x19, .40 S&W(TBA), 12Guage(Prototype)
-50 to 100 round magazines
-Non Reciprocating Charging Handle
-Pistol Version Available
Price: 600-1000 USD Depending on where you find it.
Note: Magazines are VERY Expensive, and the 100 round magazines are not very reliable. I've done some accuracy tests, and they seem quite good. Beware of the bolt hold open device, as it can break easily.
Ruger Police Carbine
Calibers: 9x19, .40 S&W
-Takes Ruger P Series Magazines
-Basically a scaled up 10/22
Price: 700-1000 USD
Note: There really isn't much to say about this gun. It's reliable and is pretty standard, but is kind of pricy compared to other Pistol Caliber Carbines for what it is.
Marlin Camp Carbine
Calibers: 9x19, .45 ACP
-Uses S&W 59 series magazines in 9x19
-Uses 1911 Magazines in .45 ACP
-Substantial Amount of Aftermarket
Price: 600-1000 USD
Note: These have not been made since 1999, but parts are still plentiful and since it can use 1911 and 59 Series magazines, magazines are still produced
Calibers: 9x19, .40 S&W, 10mm
-Can be converted to full auto if you have a registered H&K Sear
-Is an MP5
-You will be able to brag
Price: 1400-3000 USD
Note: MP5 clones are very expensive for what they are. The magazines cost about 60 USD and can only really be found on one website. If you really want an H&K Pistol Caliber Carbine, look for the USC. They are cheaper and about the same quality, and also have a bolt hold open similar to that of an AR-15.
