It's a screen shot from the new Star Wars series Andor. Star Wars has usually taken real firearms and added stuff to them to make them look like sci fi weapons. It's one of the things I like about the Star Wars films and shows.
To me, looks like one of the under-folders, with tge safety removed, front sight and cover dressed up, and the mag decorated.
I also like that a lot of snowflakes are upset because Star Wars had GUNZ!!!!
