Welcome Aboard !- Most of us here are rolling our own 115gr or 124gr for target and competition. The barrels seem to be cut for 124gr, but really anything that chambers well will shoot good in these guns. (Note that "
chambers well" is the operative phrase.)
- For SD we prefer the ammo with a rounded ogive, rather than conical. (Like Speer GoldDots, Fed HST flavor of the month, etc.) This helps prevent feed issues. If you want to load your own, then check out
Berry Mfg Hyper Hollow Points.
Just stick with the standard
FMJ until you digest all the information in the ammo buying Stickie at the top of this forum. Some of the really fancy (or strange)
Buffalo Bore or
CorBon SD ammo may not even fit the CZ chamber. The CZ chamber can be
fairly choosy about ammo, so check with us before buying huge quantities.... that you may not be able to shoot.
Lots of great info already compiled there for you.
One last thing... Shoot at least 500 rounds while using both mags. These guns run tight and need a small break-in period, with extra lube on the rails.
