Geared Up! DIY Tracer Pistols
While a lot of other Overwatch heroes use weapons that are... shall we say, difficult and dangerous to replicate in real life, Tracer's twin pistols are light-weight and relatively straight-forward weapons. They just also look badass and sci-fi as hell.
The creation of two Italian engineers, these DIY airsoft guns based on Tracer's pistols are a little more within reach of the average hobbyist, though they still represent a lot of time and engineering. And it goes without saying, but these still aren't cosplay convention friendly, much as we might wish.
Still, who wouldn't want to take these for a spin, given half a chance? Chronal accelerator definitely not included.
