Right now there is a listing on GB # 468967293. Glock 22 3 rd gen, NS, 3 mags, It is very nice and marked Morgan County Sheriffs Office. Seller is PolarBear, price is 485.00,+ 20 ship. On the high side. Also GB 460467033 GL22 3rd, NS, 1 mag, Marked San Antonio Police, excellent/unissued, 439.00 ship included. Mags on both guns are marked LEO only, I have bags of G22 mags. I have seen the the SA PD and they are excellent. Is this the type of marking you were looking for? Be Safe,
Are you looking for guns marked from Dept? As for "marked" magazines, Detroit had their mags marked DPD, I know of no other dept that did. Or are you asking for " Law enforcement only" marking? Let me know.
