have one as well. as has been said. needs a little stoning on the trigger and sear. I happen to have the jigs for a 1911, so it was no big deal. Since the hammer spring is so light on these, they clean up really well and really lighten fast. The trigger is now just over 2.5# and is among the best triggers on my 1911s.
They have also been known to be rather picky with ammo. very much so that they kinda got a bad rap for it.
Since I got the gun for $250 I was willing to play a bit. I ordered a number of replacement springs and proceeded to go to work. I polished the crap out of the ramp and made myself a jig to polish the bejesus out of the chamber. In addition, I polished the rail and slide guide on the outside of the barrel. after some bore paste and a truly obscene amount of flitz. the chamber is like a miror lol. Setting the original spring aside. I went to work on a new spring ended up with a mix of cutting and stretching one of them after some testing.
The result has been completely worth it. it's now 100% with all the ammo I have. (mainly automatch and rem golden bullets), and it's rather accurate to boot. it's a hoot to shoot. One thing I have noticed though is that there's a significant dwell lag with the slide. it's comically slow to return to battery. Which has actually been a good thing for me, reminding me to concentrate on follow through for my shots.
If you get one. I still have a few extra springs that I ordered. I would be willing to send you one, if you want one to tune yours.
also, they take the plastic kimber 1911 22 mags as well and they feed perfect.
edit - i just now realized you were looking at the 22 mag version. I have the regular xt 22 one that also comes with a 45 barrel.
