OK, so if you're here, you probably own a firearm of your own, or you may be looking for one. Owning a firearm, such as a pistol, is a lot of fun but it's also a lot of responsibility. One of those responsibilities is the proper care and maintenance of your gun. If you want it to last, taking proper care of it is the key.
First off, there is a difference between maintenance and cleaning. One is done to keep the gun ready on an ongoing basis, and preserve it long term (maintenance). The other is cleaning he weapon after use. Both are important, but both hold slightly different roles in the care of your firearm.
Before we get into the specifics about caring for the guns, let's pause here just briefly to go over where you do your work on them. Select a place that's clear of clutter, and with a flat surface. Avoid places that have carpet or rugs as they will suck up and eat small pieces.
Most importantly, make sure the gun is empty, and if you need to, remove any and all ammunition from the room. I cannot emphasize this enough. Far too many people have been hurt or injured by someone cleaning an "unloaded" gun. Before you even start doing anything to a weapon you bring into your cleaning area, clear it, check it two or three times, then recheck it. Once you know it's empty, and visually as well as physically check the chamber, you can begin. This goes back to the standard principle that you should treat every gun as loaded until you check it for yourself. When you sit down to clean or work on your gun, make sure you check to make sure it is empty first.
