They quit making the all stainless Sig 226 about 2 years ago. I was lucky enough to pick up a couple of them when I found out they were getting rid of the sub-model / my dealer got me one in 9mm and one in .40 .
It is too bad they are gone. There is the elite and others still in the regular 226 lineup - but the X-Five is really a different gun. One X-Five has an adjustable trigger and lists at $2,786 / there is a competition X-Five with no adj trigger on it at 4 1/2 lb pull - different grips / then there is the tactical model, but its blued, no adj rear sight, etc so its not even the same as the old all stainless. The X-Fives are all SA guns / with a thumb safety / they all have 5" barrels - so they are a lot different than the standard 226 models / and very different than the all stainless 226 model you remember ( with a decocker, etc ).
I do recommend the top of the line X-Five / I have one in .40 and its a great gun / but its a beast at 55oz with a full mag in it too. I like the trigger on mine at about 2 1/2 lbs / its a specialized target or competition gun - and its fun to shoot in .40 / and I've been looking for a used one in 9mm for a few months - street price on the top of the line X-Five is about
$ 2,375 in my area. It will not take the standard Sig mags / they put out a special mag for the X-Five - so order a couple of extras if you order one of their guns / but it is also a 14 round mag in .40 giving you 2 more rounds than the standard Sig mag in .40 so thats a plus too.
