Now that the wife is asleep (she hates the smell of Hoppe's), I'm gonna take down my new MP9 and give it a good cleaning. This is my first polymer pistol and I'm wondering if it's kosher to use solvent on the plastic? I'm guessing it won't hurt anything, but figured i'd ask just to be sure. You guys have helped me a lot already and i haven't even been able to shoot the thing yet. Just one more day... I can't wait!!! Thanks again for the help.
