Is there any problem with running the supplied plastic brush (dry) through the barrel of a new glock 17? I know this sounds stupid but... The instructions called for a cleaning of the gun before first use and, because my local dealer told me the gun came with a cleaning kit, I didn't have any solvent or gun oil on hand. I figured it didn't need much of a clean before being used and assumed running the dry brush through the barrel would be enough. Are there any issues with doing this?
