I dont think I will buy another factory Glock again ; )
Well unless someone posts a $300 glock
Polymer80 PF940CL™ 80% Hybrid Compact Frame Kit. Uses a G17 slide on a G19 sized frame
Glock19 lower parts spares I had laying around plus some used parts picked up at shows or online forums
Completed the lower under 1hr. Used an x-acto blade to score the sections to be removed. 80 & 120grit sandpaper finish the cuts. No dremel or power tools were used
I used a hand drill
I will add pictures and the process I used a little later
Very easy to do.
