I have one of the MS Ultra Tac versions, and like it quite a bit.  I did have trouble with mine, and ended up installing a flat bottom firing pin stop to help with slide speed.

Also, the only mags I can use to make it reliable are the Tripp Cobra Mags.  Using any other mag, and I have tried several brands, and I usually don't make it through the mag without a stoppage.  Tripp mags have run 100%, though.

Haven't checked this forum in a while...

I mentioned in some other posts that I can only get Tripp Cobra mags to run consistently in my TAC Ultra MS (the box says "Tactical 2011", but it has the full rail and all...).  I was having trouble with the slide outrunning the magazine.  I also fitted it with a flat bottom firing pin stop.  Since getting the mags and doing the change, the pistol has been 100%.

I really enjoy the feel and the balance of the pistol.  I did change out the red fiber optic for a green/yellow, because, for me, the red did not light up very well.

I paid way too much for it when I bought it.  It had just come out, couldn't find them in many LGSs, I wanted it, etc.  Did I mention I paid way too much?  TOO MUCH!  Oh well, in another 10 years I'll probably get over it.  It was lower than the MSRP at the time.

Would I buy one again, at the prices they go for now?  Sure, knowing that the factory mag will need replaced, at least.

Mine is just an Ultra Tac MS model, but one of the first things I did was fit a flat bottom firing pin stop.  It slows the slide cycle just enough to increase reliability.

Inexpensive (http://www.egwguns.com/firing-pin-stops/), and just takes some time to file things so it fits just right.  I had a problem with my slide outrunning the magazine, but from what I hear, it's a good all-around mod to make on your 10mm.

Nice.  I had a 1006 some years ago and had to sell it during hard times.  I'd give up my Glock20 in a heartbeat for another one!
