It's been quite a while since anyone posted about Glocks or usable mods for them. Here is a G17 gen 3 that I am using as a host for a Recovery Tactical 20\20 pistol brace with front magwell and optic rail. I have an inexpensive RDS mounted on the rail, an ETS 30 round mag in the magwell and an Alpha Wolf G17L (6 1\2") threaded barrel in the Glock. I just put it together 2 days ago, in the middle of a multi-day snowstorm, so no range report. I've had the 20\20 brace for a while and MEH, but with the addition of the optic rail it seems like it can be a very useful tool.
