The CZ OEM wood panel grip inserts are very thin and prone to “cracking” when firing the pistol, per other members.
One member glued his back together with cyanoacrylate glue – “looked ugly, but worked”.
In my CA glue research, I discovered that hobbyists who make wooden pens/pencils use it to coat there items.
They use it to strengthen and finish their projects. My inserts are coated front and back.
I used a CA glue called Starbond EM-02. Its specific gravity was just above water, so it soaked in.
Hint: If you're thinking of using this product, its cure can be accelerated by the moisture from your fingers.
USE the blue nitrile gloves, and apply with fingers in multiple light coats. I just squirted it on the back.
