The first time is always the most awkward. Of course, make sure you practice proper gun safety when you handle your tool!
On a serious note, we must remember that most people are not diligent maintainers of their firearms. The Model 539 I bought last month required involved effort to field strip, and the reason why was apparent- I found a good 20 years' worth of accumulated crud, carbon, and lint residue. Its a miracle the darn thing wasn't seized up.
If the previous owner of my firearm happens to be reading this-dude, you suck. I realize these guns are tough, but you want to clean them at least one every decade!
