It happens with the magnum as well, always test fire any pistol you pick up before you get into trouble and need it.

The blurry vision is supposed to go away once you recover, if it doesnt go away after you recover hit escape, configure, video settings and then go back to the game, vision should be cleared. You may have the blurred vision or a graphic glitch return on each new server you go to until you die, the above fix will have to be done each time.

Steps I have taken:
Opened tcp and udp ports 2302 through 2307
tried every connection tweak I could find
Restarted router
Restarted Steam
Restarted computer
Verified the integrity of the game cache
applied every lag and fps fix I could find
Disabled and uninstalled zone alarm firewall
Disabled windows firewall
Disabled and shut down malwarebytes anti malware
Disabled and shut down Avast antivirus
Run the program as administrator
Manually updated Battleye.

I also have tried picking only servers with very low ping and 0 people on, still have the issue on about 85% of the servers that i tried.
