I'm a new member as well, have a handful of handguns. My first Glock was a recent purchase also. A gen4 G19 also. I absolutely love it! My advise is to clean your gun at a minimum of every other session or if you haven't used it in six months. I clean after every session. It will give you a better idea of your new gun and get you more familiar with it. Congrats on the handgun.
