If you are wanting to stick with the 9x18 cartridge, you may want to look at the Hungarian FEG P-63 (alloy parts, thus lighter) or Polish Radom P-64 (all steel and heavy).
Both are smaller than the CZ-82, but just as reliable and just as accurate. I carry my P-64 sometimes in an ankle holster, sometimes in my Wrangler pocket. Yes, they are heavy, but smaller and thinner than the CZ-82.
Willing to go with a different round? The options are endless. Find something that is comfortable in your primary carry position.
I have tried many and carry a variety, but my pocket/ankle carry has evolved to snub 38's or 9x18 com bloc single stacks...both are as reliable as I can find.
Have fun shopping, but DON'T SELL the CZ-82...I think you'll regret it sooner than later.
Whoops, sorry. I just noticed you're talking about a CZ-83.
I still recommend com bloc weapons 100%, and I still recommend keeping your CZ-83.
Lots of nice, smaller .380's out there to compliment her and keep your ammo interchangeable.
