Check the Emojipedia chart. Apple switched from a realistic gun to a water pistol in 2016. Two years later, we see the same move by Twitter, Samsung, and now Google.
A year after Apple made their move to a water gun, Facebook shifted to a more photo-realistic image.
And, interestingly, Microsoft went the opposite direction, moving from a sci-fi ray-gun to a hand gun.
So that leaves Facebook and Microsoft, sticking to their guns. But:
A Facebook spokesperson confirmed to Emojipedia that a toy squirt gun will now be replacing the gun emoji design on Facebook platforms.
Microsoft. Last gun standing.
UPDATE: From Microsoft:
We are in the process of evolving our emojis to reflect our values and the feedback we’ve received. Here’s a preview: pic.twitter.com/BlB3yYTSht
