Try searching for "392s" or "397s" You should come up with quite a few posts
I have the 397s and like it. The stock is solid and feels good pumping and shooting. I have no issues using the open sights, nice cheek placement on the stock. Is there an issue using non-lead pellets? I am ready to order ammo and was going to try some alloys.
I've also found that perhaps the valve is now different - so that after 10 pumps, the excess air bleeds off. I'm guessing that the pump volume has decreased then - since the velocity with lead pellets is still the same as the old 8 pump version. I wonder what the benefit is to having 10 pumps that yields the same power that 8 pumps used to.Also found that the pump arm is now longer, presumably giving more leverage. This is all unfortunate. Increasing the length of the pump arm, and increasing the number of pumps - but with no increase in power. Seems like a missed opportunity.
The wood stocked 392-397 are still on Crosman sight. I think the new valve uses a Mrod style valve with smaller delrin instead of brass poppet.
