Pros:

It's a very good Skin
sounds are good 
idea is excellent
Best pistol skin i ever saw

Cons:

the silencer texture shows me purple black box color.

the silencer texture of the beretta's  works properly when you have the Glock 18 (silenced uzi) in you're addon list.

Conclusion:

if you could fix the silencer color texture then this is the skin is for me to keep playing ,it only works 100 percent when i'll have the silenced glock installed in the addon list ,then the silenced beretta's uses the silencer skin of the glock
