...im leaning towards a commander sized gun for the extra concealibility.
also, im leaning towards a "smooth" gun. i.e. dehorned, serrations instead of checkering ect. i have heard that 20 l.p.i. will tear up/hang up on your clothes , and for non l.e.o. its not really worth the hassle.
...
thanks.

I suppose that if one insists on carrying OWB, the Commander-length slides afford a slight advantage in concealment. For me, the slide-length issue is moot, because I carry IWB the majority of the time. OWB requires a longer jacket/shirt than I usually wear for our climate.
I'm sure that any of the LTW 'smiths can make a Commander run reliably for you, but the longer slide of the Government model allows more forgiveness in terms of tolerance stack ups and such. Many of the hard use crowd insist that only a 5" 1911 can be truly reliable. I tend to think that the 5" guns are a bit less finicky when it comes to ammo and spring-replacement intervals. While it's true that velocity will be a bit better with the 5" barrel versus the 4.25" barrel, Doc Gary K. Roberts has reported that there is no practical difference in terminal effectiveness (

If wearing suits or sport coats or similar garments with delicate lining, then I suppose that sharp checkering would be an issue. This would apply to grips as well as frontstrap and MSH treatments. I'm personally more concerned about how 20-LPI checkering wears on my girly hands. Regardless, there are effective-though-less traditional alternatives to checkering (e.g., "golf-ball" dimples, scallops, conamyds...).
For IWB carry, frame length is more of an issue for concealment. This can be addressed by skipping add-on mag wells, using an Officer-length frame, or Bobtailing a Gov't/Commander frame. Magazine choices seem to be somewhat more limited for Officer Models, and I prefer to have common magazines for all of my 1911s, so for now I'm sticking with full-length frames.
If I were in the market for a max-concealment, carry-a-lot, shoot-not-so-much pistol, I might consider a Government model with a Bobtailed aluminum frame (with Rogers scallops/dimples).
