Back in 1976 I bought a Steyr Mannlicer Mod M Professional, One of the first fiberglass stocked rifles. The magazines are Polymer and I never had a bit of trouble or breakage to to wear or what have you. I would not have a problem with the follower in the CZ 9.3 x62. The Polymer they use in firearms in general is very strong and durable. Since its a 98 action or a copy of one, Brownells will be able to fix you up with a follower in metal if it keeps you awake at night.
