I think it’s a fair price, but I wouldn’t buy it either. Any gun that’s had undocumented modifications to the action can be a can of worms down the road. Especially if you don’t work on guns. At a minimum I would want to field strip, inspect and shoot 50 rnds; not usually an option at a gun store.
The grips are a personal choice. I find the AL grips too thin for my grip. Here in AZ they get incredibly hot and have zero thermal insulation, which I found kinda of a problem in a carry gun.
