"If it ends up being real expensive, forget it."
Southpaw: Although it's a bit early for speculation, if indeed CZ produces a 97B in 10mm, then it shouldn't be priced (retail) for any more than the same gun in .45acp.
And from what I've seen, the .45 97B is pretty affordable. While retail varies, dealer price is about $475-$480.
Personally, I don't think that's bad at all for what your getting: an extremely accurate and reliable big-bore autoloader.
The reputation of CZ's autoloaders generally is that they're more reliable and more nicely finished than Tanfoglio's clones, which mimic the CZ-style without CZ's attention to detail or unit-to-unit reliability (i.e., less quality control).
If Glock's large-frame models 21 (45acp) & 20 (10mm) are any indication of industry pricing, the fixed white-dot sight units are both running the same: about $480
dealer price (again, end-user retail will vary a bit from locale to locale).
But I would expect a 97B in 10mm to be priced within a few dollars, either way, of it's .45 counterpart.
Stay tuned.
