The water pistol orange on the X website is changed to a genuine gun.

The “Pistol’ emoji now gives you a gun, not a water-pistol on Twitter/X
After six years of using the pistol emoji, users on Twitter/X now see an image of a pistol instead of a pistol. Apple, Google or Twitter are not responsible for the existence of a particular emoji. It is up to the Unicode Consortium, and its annual decisions. X is no exception. It has its own graphic representation. Today, X demonstrated this by going against industry standards. Emojipedia reports that Twitter/X updated its emoji for the word “pistol” and turned it into a picture of a gun. Emojipedia’s chart shows that the pistol became an official emoji in 2010 and Emojipedia also has a chart of its design since 2013. Microsoft designed the emoji to look like a Buck Rogers style ray gun. Apple changed the emoji from a gun to a water-pistol in 2016. This was not the only change Apple made to an emoji related to firearms. Google, Microsoft Samsung, Facebook and Twitter all agreed to Apple’s emoji changes by 2018. Each pistol emoji had a different image, but they were all water pistols. Twitter hasn’t announced the change and because each platform controls the appearance of emojis, the old water gun emoji is still visible on the iOS Twitter application. The new design is only available when adding it via a browser.

This included the “Pleading face” emoji. However, this appears to the first intentional revision to a prior design idea. Separately the Unicode Consortium is considering proposals for new Emoji. If they are approved, they will be added to Apple devices in a matter of months.
