Basic S&W or Kimber are not so great guns for the price. You need custom shop ones and they cost more and are rarely available at EU. Sig needs sig parts to fit at all.
All USA made guns and parts are hard to get in EU, so Bul and STP are almost the only options. I would get STP, you might find a decent priced one or get STP Sparta and replace some parts(it's not made in Germany).
It's really sad that we are not seeing any USA guns anymore, but it's politics. My warranty case with STI / Staccato never realized.
