This is a older build in the process of getting a makeover.
First built at least two years or more ago and started with an Advantage Arms 22conversion slide.
This is my fun pistol I carry around the garden for some shooting fun during the summer.
The only frame mads done to it was removing of the rail system and some stick-on rubber grips.
My plan for this makeover will have a lot of frame mods with stippling and paint.

You can see that all I did when first built to remove the rail system, I just sanded off all the rail tabs.
Now this makes it easy for me to make a well to hold JB Weld with tape.

The step on the nose of P80s has already been sanded off so all I have to do is match a flat surface, just make sure you have enough JB Weld to work it down to a flat surface.
TIP: If you can, pour JB weld in one step. When it is dabbed on over and over again, I think it traps air bubbles that create pin holes that will have to be fixed.

I roughout with a carbide burr.

Flaten out with a sanding drum. Remember to leave a lot of material for fine sanding and shaping.

I dabbed the JB Weld on, and you can see what happen, air bubbles trapped forming pin holes after shaping.
There is still extra stock that needs sanding but if I fix pin holes at this step it makes it easier to blend in.

You would think you could just push some more JB Weld into the pin holes and that would fix it, but what happens is the JB Weld does not hold or get another air bubble trapped and comes out again. SO, what I found is making the pin holes bigger allows air to be pushed out as long as you push JB Weld in from the side pushing air out as it fills the hole.

The smaller pin holes will sand off when fine sanded or will fill up with paint so just worry about the big holes.
Now just blend down and fine sand to shape.
