I use both Silver Bear, Barnaul and Brown Bear in both my CZ-82 and P-64 without any problems.
I hope those who are purchasing Silver Bear JHP aren't expecting anything that resembles expansion, because they don't (expand, that is). Even a point blank shot into bare plumber's putty (that will typically over-expand and fragment JHPs) will only sometimes yield a strange looking bullet where the hollow cavity has been enlarged and part of the side has been folded down, but not appearing anything like "expansion". For the most part, they won't expand even then and penetrate nearly as deep in putty as an FMJ.
I don't think LVE's Silver Bear 94gr JHPs will expand under any circumstances on the street. It's a shame as the 115gr and 120gr versions expanded wonderfully in similar tests years ago.
However, they do have a flat meplate (if you consider the hollow cavity a flat surface as it's not prone to expand) and work for the most part like a truncated FMJ, so I still use them if I carry a 9x18. I suspect the wound caused by their profile may increase blood loss, which is what usually causes incapacitation in the first place (if a hit to the CNS isn't made).
They're also cheap enough for target work, costing about a dollar more than FMJ, so the cleaner holes they cut in paper is useful as well.
