These are used 10-round factory Glock magazines that were traded in from a police department. Glock magazines have a hardened steel insert encased in high tech polymer. This polymer coating protects the magazine and prevents deformation, even when dropped from a great height.
Price is for one Glock 17 police trade magazine.
Bought 3 Glock 17 10 rounders as police trade in. Initial order had one mag missing 3 parts. Notified customer service and was sent a replacement the next day. 5 star service rating. Products had scuffs on bottom but does not affect function. Will definitely buy again.
