What do you think of buying a "law enforcement trade" from Summit Gun Brokers? I wonder how many rounds have been fired though them? My cousin is a HP and is given a large amount of ammo each month he must use. I forgot the amount but know those guns get a lot of use.
Summit is an awesome dealer and everyone I know that bought guns from them have been very very pleased.
A lot of departments will only do quals once or twice a year. Some do it every quarter. A lot of the time it's only 2 or 3 mags worth.
LEO trade in's are carried a bunch but usually have little use on them. Check out a user named twogunjay on GT, last I saw he had 3rd gen G22's with night sights for $365 shipped.
