yea as you can clearly see in your 1st pic the mag only goes half way back while on your drop images it goes all the way back. This is a bit of an issue but its simple to fix with paint as I have after I DL ed it.

Look at first screen with CS:CZ P90 you see empty magazine. Next download and see dropped P90 with GIMP/Paint maximize it and you see it's no going to far:P.
