I'm looking at the Crossbreed for my 642. I've seen tons of positive reviews of this holster, most all of the reviewers using it with smaller semi-autos like the Glock 19, or Ruger SR9/40c. Past experiences with other, cheaper, IWB holsters for the 642 haven't been great. On top of being unstable, they were very uncomfortable. Just wondering if anybody's used the Supertuck with a j frame, or other small revolver, and what the results were.
