the ppsh is a bit small and the SPAS-12 is completely wrong, it shouldn't have a full-auto mode and you can't aim down the sight, sure it doesn't have a sight but neither does the medic shotgun

Not going to say anything on PPSH and SVD since Flux already said that they wont be added.

So:

PP19 - Animations are a bit weird, plus it has explosive ammo.
If the weapon stays like it is, might be a good addition to Demo, give it a little more of variety in weaponry.
If it stays without the explosive ammo, i dont know.. doesnt seem to be worth it.

Glock 17 - very nice sidearm and it can be used as dual.
Recommend it to be used with survivor level 5 spawn instead of mk23, since mk is already used by sniper.

Aks74u - Didnt like it one bit. Insane recoil, too innacurate and weird animations when shooting and reloading. The red dotted Aks74u is better than this one for sure.

Charmer - very nice weapon. Would be a great addition for RnG or even Comm.

Shield - little weird but does what it´s supposed to i guess.

Galil Arm - Insane recoil animation. Very hard to aim with ironsights, since as soon you start firing, it will block half of the monitor. Not worth it in my opinion.

Galil - not too bad, better animations than Galil Arm, making it usable. Comm perhaps?

L96 AWP - Liked this sniper a lot. Would be great for Sniper perk.

M60 - Very nice machine gun with incredible low recoil and a great ammount of ammo. Worth it for Engineer perk in my opinion.

Protecta UM - Way better than our current protecta. nuff´ said!

UMP 45 - Seems to be a nice replacement for our current UMP in RnG. the Ironsight (Bullpup ironsight) makes it easier to aim.

Spas12 - I agree with Synth. its just wrong and weird. Dont think we need it since it seems to do the same as combat shotgun.

VAL - Seems to be a nice weapon, probably good for RnG

USAS 12 V3 - Best weapon out of all of these in my opinion. As i told Flux, i suggest it for Supp xD

I dont think i skipped any.
