I have no idea, so I resorted to google. This quote is from some gun range in the 405 area code.
"Besides the regular gun cleaning I do, should I have my gun cleaned by the Gunsmith?
Yes, a yearly deep clean is the best method of maintaining the quality life and value of your firearm. The number one cause of malfunctions is dirt. The Gunsmith department will tend to all the small details and make sure that problems of rusting and buildup are cleared away. Every firearm should have a yearly checkup and cleaning.
PROJECTED COST (Deep cleaning $45.00 & regular clean $ 35.00)
