If anyone looking to buy a Glock is: Prior or current: Police, Fire/EMS, or military; you can get a great deal on ANY glock from the Cop Shop in Baltimore.
I purchased my two from them (19 and 23) and paid $450 a piece ( included 3 mags, reloader and bore lock) plust state fees etc.
Very happy with the transactions!
You will need the Appropriate ID from the Public Safety or military for the sale. best prices I could find in the area (believe me I'm CHEAP)!!
