Trevor, thank you for response!
New to me, but I shot it about 8 times soon after purchasing. I didn't notice anything then, but I didn't test the safety.
I didn't want to shoot it until I addressed the stock. It has been apart since then.
It had one hairline crack at the rear of the right-side plate, a crack in the webbing inside the webbing from the lower left inside the inletting.

I removed the stock o determine its conditon. I did refinish the stock after repairing the cracks and this is the first time I've had it back together.

I dread taking it back apart, but I could put a shim under bottom trigger tang at the rear screw.
I'm open for suggestions.
