New CRB in Canada

Owned a CRB for several weeks now, love the gun, cool factor is off the charts. However I too am experiencing the typical issues, jamming on second last round and stove piping........... Damn. Hopefully can find advice here on how to fix it. Kriss pretends they don't sell guns in canada so a buyer is alone, buy it and hopefully you don't have any issues because if you do...... You're on your own.

Maybe try a hotter round or a larger caliber to give the firearm more inertia to function with.

Which ammo do you use?, obviously we can't use a different caliber, they're all .45, I'm getting some different ammo to try.

I haven't even got mine yet but factory 230 is a good bet. Avoid the low recoil stuff.
