One thing I didn’t see that I was wondering about was whether I could use the M backstrap and also the jig or else the thumb web position would be inconsistent for me between generations.
Looks like a yes.
I’ll glue the part of remaining strap in place.
Dry fire presentations, the dot is spot on using my CZ index.
Cut Gen 4 frame with M backstrap I’ll have to blend.
Some pictures of cut Gen 3 frame too. .
So far, I LOVE it.
You will get a better, cleaner pattern if you first grind off the OEM nipples so you are working with a flat surface... That will eliminate the extra plastic oozing around. Just use a drum sander wheel on the Dremel and knock down those nipples... It doesn't have to be pretty or perfect since it all gets covered over.
Also rotate the iron a bit each time you use the Wagon Wheel... Like 12:00, 2:00, 11:00, 1:00. Just enough to create a random texture so the lines from each impression don't line up. And don't be afraid to overlap a bit more if you want a truly random effect.
If you look at mine it is very hard to notice one specific "wheel" amongst the chaos.
Also, be very careful with the thumb ramp depression area... The frame is Very thin right there and a heavy hand might melt through it.
