Thanks to Black Friday I completed the poor-man's PCC GLOCK 17, to go with my existing brace of pistols. From top to bottom:

GLOCK 17 Gen 2 with ENDO Tactical buffer tube adapter

7.5" Poverty Pony Pistol

Ruger Charger Takedown with Copper Custom buffer tube adapter

All of them are capped off with KAK pistol buffer tubes, and Shockwave Blade pistol braces. The GLOCK and the AR have translucent ETS magazines, which are OK. They look better than they feel. The Charger doesn't have a suppressor yet, but it might in about a year.
