Hey everybody.
I'm a little scared. I have cleaned my Sig
twice since i got it months ago. Yes, twice, and I carry it outside with me all the time. I looked at the back of the hammer today and I can see the gunk on it

. No one throttle me, please.
Cleaning it scares the crap out of me and I don't think that I know what I'm doing half the time.
First, I'm always afraid that my bronze bore cleaner will scratch up my barrel

, as it takes some force to get it in there and turn with the rifling. The bore cleaner's package did say that it was 9mm, so it should fit. Maybe I'm just being paranoid about it?
Second, I use Hopper's #9. Is that pretty good for the P250?
Third, the rear sight seems to be rusting a little, but I have taken great pains to keep it from getting wet and neither the car nor my apartment has issues with moisture. I run the air conditioning in both constantly, but I don't think that would have anything to do with it.
Anyway, if someone could please help relieve my fears without making me feel more like the unresponsible gun-owning moron I am

that would be great!
