Thanks for all the good information. Suspenders are actually in my wardrobe. OWB is looking pretty likely. I don't mind paying for quality just trying to limit some trial and error cost. I definitely want great concealment, ran into issues with OWB concealment on a 1911 that I fixed by switching to IBW, but then felt uncomfortable with a SAO design and a hammer drop away from an unintended discharge into my leg. Switched back to my wheel guns, and am trying to nail down the best set up.
May just get a new shoulder rig for the 629, and switch to the premodel 10 OWB. I just feel a little under gunned with a .38.
You guys are being a great help though, thanks a lot.
