I picked one up a while back along with an "Army" model. Both were supposed to be 9mm, but the Tank Commander came in in 45. I ended up taking both.
I have one of their "Service" models in 9mm, and was looking for basic, GI guns, and thats pretty much what I got. Both seem to work OK with good mags, and are pretty reliable, but they are not 100% and would need that little extra you would do with any of the Series 70's type guns to get them comfortably reliable with a mix of ammo.
I actually would have preferred the GI type sights on the Tank Commander, but the sights it came with are fine. A little glo orange nail polish on the front sight makes it quick and easy to pick up, either way.
I swapped out the walnut grips for a set of GI plastic, for the looks and they are a bit more aggressive in texture.

Oh, and there is a simple, "poor boy" version of front strap checkering/stippling. Its called skateboard tape. Ive been using that method for a number of decades now, and on pretty much every autoloader I have.
