Depends on what context they are mentioned in, focus on the word "mentioned".
/out/ activities or jobs like hunting and being a ranger require a gun. You also see guns mentioned in homeless or hitch hiker threads, prepping too.
A thread saying "What gun does /out/ take on trips?" with a close up of a Glock, in what probably is OP's fat hand with a vast forest in the background, taken from a viewing platform to which OP drove with his mom's car is a thread that is primarily about guns and not /out/.
