I know of a few guys who shoot the 9.3 in the CZ. One or two left it stock and the others just glassed it without the cross-bolts. I don't think the stocks will crack under the 9.3's recoil but there's no harm in glassing the stock, it may shoot even better. In fact, in a little while, I'm going to pillar and glass all my RSM's just so that I'll have rock solid platform from which to launch my rounds. As to the pillar bedding, the benefits are that you can never over-compress the wood over time whenever you take the barreled action out of the stock.
