This list was inspired by SimilngWolf. I have not fired many of these weapons, I am taking the info from other sources.
KRISS Vector Edit
Using a unique mechanism to reduce recoil to almost nothing, the Vector has three options on the selector: safe, semi, or automatic.The Vector I chose has a tan finish, a foregrip, an integrated laser, and a suppressor.
-The Vector fires the common .45 ACP round, and ammo can be shared with various other firearms.
-The vector has an upper and lower rail to mount attachments, as shown above.
Light & Compact
-This SMG is pretty light, so it is easy to lug around. It's also pretty small, at 24.3 inches(620mm), just over 2 feet (620mm) with the stock unfolded.
-You aren't likely to find this gun unless you live near the KRISS USA plant, or are some Special Ops guy.
High ROF (Rate of Fire)Edit
-Some may think this is a good thing,but it makes you want to "spray-n-pray". This wastes ammo in its 30-round mag.
-Just as the Vector is rare, its mags aren't so common.
SIG SAUER P226Edit
Some may prefer their heavy .50 cal Desert Eagles, but I prefer the tough,
reliable P226. It features a lower rail,external safety,and the ability to drop the mag and still fire. It comes in 3 factory calibers: 9mm Parabellum, .40 S&W, and .357 SIG.
-The 9x19 Parabellum round is very common, and can be found nearly everywhere.
-It can hold from 10 to 20 rounds, very good when there are large groups of undead or bandits attacking.
-This gun can be dipped in mud, put in the freezer, and can still fire. Impressive, right? This kind of reliability is good when you are in tough conditions
-A problem most pistols have. If you want to take something hostile down,best do it at range.
-You need a certain stance to fire a pistol, or you will hurt yourself or someone around you.
