These are great deals! The constant trade of LE trade-in guns is really something. It seems many agencies and departments are on a merry-go-round of sweetheart deals where brands attempt to get in and displace a competitor - offering to buy up a department/agency's current stock of weapons to incentivize a switch. Gen 3 Glocks can be found in bulk/wholesale now at $100/ea in many cases. Same for older Sig P320s. M&Ps, Beretta, etc.
Especially now that .45 ACP, .40 S&W, .45 GAP, 10mm have "jumped the shark" in LE
LE surplus/trade-in wheel guns however, seem to fetch a premium. I would love to have a modern era FBI S&W Model 13 in .357. (E.g. duty weapon of Special Agent Clarice Starling)
