I found that the safety wouldnt function without some releiving of the stock as well. I also had a issue with even reaching the safety because of the thickness of the stock blocking a natural reach with the thumb, so that area was sanded down. The stock responds very well to these mods.
you can see the area modified compared to the pic in the post above,
The stock now feels as comfy as any other stock. BUT with NYS also making a thumbhole stock a evil assault weapon feature, I found absolutely no reason to use the stock seeing the weapon is considered illegal regardless of the type of stock now.
