a Glock 20 (10mm) Gen 4 upper with a matching number barrel. It has OEM front/ rear sights. It will come with OEM dual recoil spring- NO other upper parts are included. It will use the same internal upper parts as G21 gen 4.

Doesn't appear to be used much, almost no wear on the barrel. No holster wear either. Pics later.

$ 280 shipped. Payment via Zelle or USPS MO, personal check.

Again, a dual recoil will be included, but currently not pictured.

This can be swapped out using upper parts from the Police trade in G21 Gen4, along with correct mag- and you'll have functional 10mm pistol.
