Lower is 3rd Gen and in excellent/perfect condition. I bought it new to make a dedicated .22 Glock using an Advantage Arms kit. Easily less than 500rds of .22 through it. Has never been used for 9mm.
Also has Glock extended slide release installed.
Serial number is FUN*** which I always thought was appropriate.
It is ready for you to install your AA .22 slide and have a dedicated .22 Glock 19
