I haven't seen any particular problems with the Sigma/SD series using most any American commercial ammunition or my reloads, except for isolated cartridges out of spec.

Tips with a new gun are the same as for any, clean as you did, don't fill the mags full the first few times, don't ride the slide when loading, keep fingers off the slide when shooting, etc. Disassemble, clean and dry the mags periodically, don't get lube in the striker channel.
