I dont have them yet, but managed to scrape up some CZ hi caps for a Compact.
They are original CZ Compact tubes and followers, wolf +5% springs and a plastic base much like the pic above.
They should be much more comfy than the "metal" baseplate is. They add just a little for big hands. I looked for these baseplates for a while. You have to see em.....
They are new mags and a few may be up for sale.........
..2-3 at the most...anybody interested?
I will post a pic when I get them sometime next week...
Shoot well
