I'm pretty sure the Xtreme line of pistols have not come to the US yet, EAA has a nasty habit of making promises they can't keep; which brings me to zhunter's point: EAA has a tradition of terrible customer service, overpriced spare parts with a terrible selection. Henning Walgren does his best to support us, but he has only a few parts available. On the other hand, Stuart Wong at CZ Custom is a great guy who frequents this forum and will take good care of you, plus CZ USA offers a good selection of factory parts at reasonable prices. If the pistols are the same price, but the CZ is new, take the CZ.
sounds like CZ is the way to go.
