Sold my X-6 L1 several months ago. Super pistol, highly accurate, just a too heavy for me. My first X-Series pistol was the X-5 Competition. Also, a great gun. Wanted a X-5 Level 1 for the adjustable trigger. It has served me well. Accurate and well balanced. It's just a little large for my hands and heavy for my 79 year old muscles. Put it on GB about two months ago. Bids were too low; took it off. Been shooting it everytime I go to the range. Most of the time pitting it against my CZ75 Tactical Sport, another large, heavy gun for me. The X-5 trigger has a smoother takeup and gun appears better machined than the CZ. However, both pistols' triggers have an equal break. On one trip I might shoot the TS better, then the next time I do better with the X-5.
I've exchanged emails with one source of X-5s here in the US. He's importing from a private source in Germany. His guns are really expensive. The story behind SIG Germany losing their export license is interesting, involves both the US and German government units' actions.
I hope the US made X-Series, when they surface, are as good as the German made ones.
