More Improvised Firearms

 I actually like this one, a snub nose built into what appears to be a reproduction 1918 Trench knife.  The fact that I think it is cool would not influence my decision to fire it though.

.22 LR lipstick gun. Not very useful, but cool in that James Bond kind of way. 

I can't tell very much about this one at all, but I do like the "cloak and dagger" style of it.

 A variant of the classic pen gun, I like this tire pressure gun because unlike most of the pens, it still looks like what it is supposed to be.  Most likely a .22 like all other pen guns I have seen.

 Provided that you could keep the muzzle free of obstructions, this cane-shotgun might be useful. I think that those are 16 gauge shells.

 Another key chain zipgun, caliber looks to be one of the .32 Longs or maybe a Super .38. This seems like it would be safe enough to fire, but I don't like my fingers to be that close to the muzzle of any weapon.

 This ring revolver is neat, but I certainly can not think of a real use for it. I think the risk of a negligent discharge would be really high as well. Caliber might be .25ACP (which is probably the most useless modern round)

Things like this scare me. Thank god I live in a country where I can buy a Hi-Point.  :)

 This one is known on the Internets as the Frankengun. The photo was taken in Iraq, sometime around 2007-2008 if I recall. The weapon is a 7.62x39mm that incorporates some AK parts like the magazine, barrel and front sight (which seems to be on backwards-no matter, right?) The pistol grip might be from a Beretta 92 or 951 (likely the Iraqi-made copy of the 951)
 The muzzle brake closely resembles the one from the Tabuk sniper rifle. It seems to have a commercial rail system tactical light and what is likely a inexpensive Chinese scope. I can't tell if any of the other parts come from a real gun or not. My question is, in a country awash with AKs, why risk your fingers and nose with this thing?

We don't see very many improvised firearms with stocks, and that is too bad, because you are going to need all the help you can get to hit anything with these pieces of crap. It is impossible to say for sure by this one photo, but it looks like this is a shotgun given the large barrel and the padded buttstock. For some reason, I think this one is from the Philippines, which have a long history of improvised guns.
