Always take the time to properly unload your gun and double-check to make sure that it's unloaded every time you pick it up to clean it. Remember that your gun may still have a round ready to fire after you remove the magazine, so check and remove this round. After opening the chamber, look through the barrel from back to front. Confirm that no round remains inside, either in the chamber or stuck in the barrel. No gun can be considered unloaded until you have looked through the barrel. Check the owner's manual for disassembly instructions to prepare the gun for cleaning. This will allow you to access all parts that become dirty from firing.  Semi-automatic pistols and rifles will generally be stripped into their major components: barrel, slide, guide rod, frame and magazine. Revolvers, shotguns, and most other sorts of guns will not need to be stripped to clean them. Field stripping is not necessary to clean the gun thoroughly. Don't take apart your gun more than you have to unless it requires repair. Likewise, some guns can't be stripped at all and it won't be necessary to do anything but open the chamber to clean it.
