Rifle Supply has Gen 3 Glock 19/23 stripped frames for $39.99 ($100 off).  I would love to pickup one to make a dedicated Advantage Arms 22 Glock.

Kind of a waste of a pistol permit, though...  It would give me some extra parts, and maybe I could find a completed set of upper parts.  i do like the GEN3s.  

I would just buy dedicated 22.  unless you really want it on glock frame.  I have one for my 1911 but today with all the 22 1911's I would go that route.

 

I think you are right.  it doesn't seem worth the expense.  I have been wanting an LCRx in .22LR anyway.  i never use the Advantage Arms kit and should probably sell it and then I can put the money toward the little revolver.  My favorite Rimfire is a S&W M&P 22 Compact.   Of course, I always wanted a Buckmark of some sort as well.  Still, I think a dedicated 22 Glock would be pretty sweet.  I wonder why Glock never came out with one?
