Your options;
Fire ammunition in your gun that was never designed or manufactured for use in your gun and hope for the best, for you and your gun. Either the slug size, hardness, shape or charge of the ammo would be wrong. Or..
Start assembling what you need to load your own. Paradox conicals, or mold, sizers, cases, powder etc.

Custom ammo is possible but you are located outside the US which may pose shipping problems.
