I had an M85 that experienced the indexing issue. I finally replaced the crappy MIM cylinder stop...and sold it to Ttousi.
I have a 905 that I love. Zero issues and I didn't have to buy speed loaders for it. I can shoot and carry the same loads I use in my G19 very comfortably.
I'm on the fence about waiting for Taurus to make a .45 or buying a Charter Arms Pitbull.
