Sharing details and lessons learned on this recently completed project (unfortunately no "before" photos). My son had "bubba'd" an older G19 gen3 frame with stippling and application of silica grit, only he didn't like the way it turned out so the frame was basically trashed. After sitting in a drawer a few years, I had the idea of reviving it so I sanded off most of the glue/grit and stippling to get a smooth surface. I also removed the finger groove nubs. Thought about having it blasted and cerakoted but didn't want to put that much into it (famous last words).
Gave it a rattle can finish which didn't take on the first go so, resanded and used Krylon camo OD followed by matte clear coat. It's not Cerakote but it was economical. Bought a set of gritty Talon grips and applied over the paint job.
Next, since the frame was stripped I had to reacquire the lower parts including the locking block. Got a discount on one from Glockstore but it didn't fit, due to the fact that this frame was a "pre-2013" Gen 3. I finally realized I could remove unnecessary material from the frame and it fit like a glove. (Glock would also remove these thin frame areas in 2014 and later models.
Next I went on eBay and found great prices on aftermarket LPKs ($20-$40). Ordered one for $35 and it turned out to be complete crap. The mag release was too short and the trigger was stiff, probably around 10-12 lbs! Back it went and I caved and bought a Glock OEM kit for $78 shipped. What a huge difference in quality and feel!
To finish it up, I had a "spare" PSA Dagger barrel/slide upper assembly which fit perfectly. The trigger pull is smooth and relatively light (for Glocks) and frame/slide fit is better than OEM IMO.
And this is how it turned out.
How does it shoot? No idea, but I'm sure it'll be just like a Glock. Range trip TBD.
