MP5/40 and Glock 35 but with a twist

The bullets are actually Lego heads [(because Lego heads are .40 caliber)] (http://www.thefirearmblog.com/blog/2017/02/16/potd-lego-heads-40-caliber/) and the magazines on the guns should be transparent so that you can see the Lego head.

Also, whenever you get a hitmarker on somebody, it should be the Roblox death sound cos why not.
