I really can't believe what I'm hearing!?!? Don't clean your gun? Really?
MT........ Please, please, please...... get into the habit of keeping that thing clean. Clean it after you fire it. Lube and protect the bore and chamber, and give it a good wipe down and light film of oil to protect the finish and a few dots on both sides of the rails (top and bottom). At least once a month, blow the lint out of it with compressed air and wipe it down. If you carry it or keep it for personal/family protection, check that it's stored ready to rock n' roll (BUT SAFE) and practice your response.
If you don't keep your gun(s) clean, that means either you don't expect to ever have to use it to protect yourself or you just don't care whether it performs when you need it to. At least give yourself the piece of mind in knowing that the weapon is clean and serviceable and will function as it's supposed to - if and when you ever need it to. During a "use of force" encounter, it can be a stressful and unpredictable event and there are a lot of variables and things that can go wrong - if it does, don't let it be something that could have been prevented with a clean and serviceable weapon.
If you ever (god forbid) get involved in a situation where you need to defend yourself or someone else, you'll know what I'm talking about after you made a choice to pull the trigger to save your own ass. :buttkick:
That's THE most important of the (other 50) reasons to KEEP IT CLEAN.
