Oily cartridges?

This morning I took my brand-new P225 to the range. Great gun--accurate, comfortable, and 100% reliable.

When I was cleaning the gun afterward, I noticed that the insides of the mags were oozing oil. I knew that SIG oiled up its pistols before shipment, and so I wiped out the pistol before shooting it. But I didn't know that SIG also oiled up the mags, so I hadn't checked them.

Anyway, assuming that some of the oil transferred to the cartridges, would this harm the chamber? (Hopefully my concern is just overprotectiveness toward my new SIG.)

TIA.
 
Don't think it will in a pistol, but you don't want oil on a rifle cartridge as it keeps the cartridge from gripping the chamber walls causing it to transfer more thrust to the bolt face and locking lugs.
 
The manner in which the British proof rifles is to take a standard cartridge and dip it in oil before chambering. While this effect is probably not as profound in pistol cartridges, it is just common sense to keep oil out of the chamber of any weapon.

Cleaning mags before use is important. Gun Tests found that one major maker actually had a lot of grease over the inside of the mag and mag spring.

some penetrating oils (WD40) can render primers inert. in N.C. we had a wildlife officer that found that out the haed way.
