floyd,
Not all cast bullets are created equal and different pistols, even of the same make can have variances in bore diameter. I shoot cast .356 bullets out of my Smith M439 without problems. However I don't own a CZ or SIG.
I did some reading online and a fellow on castboolits.com is shooting .358 bullets with good success out of his CZ75. I suggest you slug your barrel and then determine which diameter cast bullet will work with you.
I am continuously experimenting with different 9mm cast bullet combinations and sometimes I get leading when I push the envelope. Luckily I have discovered a solution that takes the lead out very easily. My barrel is stainless so I immerse it in a 50/50 solution of white vinegar and hydrogen peroxide for 10 minutes and the lead swabs right out on a patch. WARNING This solution will take any oils and finish off your gun so be VERY careful to keep it away from your blueing and working parts.
If your pistol's have barrels that don't have finish on them that you can de-lead, and you don't want to slug your barrel, I can send you a few .356 to cast to try. I think you will need some .357 - .358 bullets in your guns though.
Slugging your bore is the best option.

I am shooting a 147 grain mold that I bought from mp molds in slovenia. I size to 359. They are heat treated in the oven and they work well. Accuracy exceeds premium factory stuff. 9mm is a relatively high pressure round, and barrel sizes run between 354 to 359 and they are all called 9mm.
This works ok with jacketed, but with cast bullet fit is far more important.

The wife and I currently run Lee TL 124gr cast LRN sized @ .357 diameter without much leading problems in all our CZs. The lead is water quenched mixed wheel weights, and liberally lubed with LLA. They're smokey as hell even with the Vit N320, but no key-holing and I can put 500 through the barrel without having to scrub it out after.
I started out trying .356 in our first CZ, and you would not believe the leading mess left in the barrel after a couple hundred rounds. We're talking lead "wires" falling out of the grooves here. Even after a few mags, the sharp inside groove corners were pretty much gone. It's amazing what 1 or 2 thousandths of an inch difference makes.

I have been using a LEE 140 gr SWC mold designed for .38/.357 loading. I size at .357 and use HS-6 or W540. The accuracy out of my Sig 226 and Beretta 92SB is absolutely amazing, well beyond what I thought they would be capable of.
I add 2 lbs of nickel babbit to 18 pounds of wheel weights and water quench. The brinnel hardness is around 25.
