How to fix WE hi capa grip safety

Stercus Accidit

As some of us know, we hi capas grip safetys dont work, its a design flaw, below is what I posted on Arnies and ASF, enjoy.


Ok, so to fix the grip safety function properly I've come up with this solution, which I think is the best so far as it directly fixes the part that is malfunctioning, rather than compensating by altering other parts as in some other fixes. - This is also how wei tech fixed it too for the 1911, but by adding metal, not plastic.

The We Hicapas grip safeties don't work, the WE 1911s grip safeties do work, there is a very small difference in the latch on the grip safety that depresses the sear disconnector (not sure of exact name).

In the diagram (I don't have AutoCad at home, so ms paint!) below on the left is the standard part, unable to reach the sear disconnector, by approx 1mm.

On the newest 1911 models Wei Tech have made this arm larger and able to reach the disconnector.

But what of my Hi capa you say?

Well you can add 1mm of material to this part and it will function perfectly!

Plastic will glue to metal if both surfaces are roughed up, easy with this softish metal and a knife or file.
I find the bond was hard to break, but make sure both the plastic and metal are rough, and fit together relatively well.

This Diagram shows how the stock part is too small on the left, and on the right with the plastic adhered. The right diagram is very similar to the shape of the new 1911 grip safety that works.

Procedure

1: Learn how to safely dissamble a 1911 type gbb, safely as a small part jumps out at a certain stage of dissasembly and can get lost.

2: Get your grip out and sand off the paint where you are going to add to, see diagram.
Now scratch the surface with a knife in a hatch pattern, the rougher the better as you will be using glue to adhere new material, superglue works perfectly.

3:Get a small piece of abs, black plastic, any plastic, and cut roughly to shape.(Not too precise as you will be sanding later.) This will be glued on, as this part will only experience compression plastic and superglue are more than strong enough. Again scratch the surface to get a good grip between the plastic and the glue.

4: Glue the plastic onto the metal, and let dry. You will find the right glue made a very strong bond.

5: Now sand away, or use a file(I had three types of metal file to get a fine finish) and try to get the shape shown, approx 1mm thick will work, or less, at less than 1/2 a mm you will find the original problem re emerging.

6: Keep sanding, refitting, testing, sanding till it works flawlessly. If you sand too much, just file down to the bare metal again and re prepair the surface and get new plastic, I had too.

7: Done, the grip safety should engage and dissengage consistently.

I Find as you are repairing the part at fault rather than compensating for it, this is the best fix.
