1 Sile? from CDNN - cheap rubber trash, avoid like the plague, yuck
2 Sile from CDNN - cheap, so cheap the screw won't line up and neither will the wood on the grip frame, also way too thick for what it is
3 Sile from CDNN - cheap but kind of good, the fit isn't perfect but not bad for the cost. I like them but they are snappy under recoil
4 Factory J frame magnas, hard to beat the real deal original
5 S&W branded Hogue Bantam, one piece kind of sticky but comfortable and good fit but only two finger grip, open back
6 Hogue Monogrip, sticky like the all Hogue but adds comfort to shooting, minimal bulk for three finger grip, covers back of grip frame
7 Pachmayr Compac, different kind of sticky from Hogue but still tacky and might grab clothing, pinky rides bottom finger rest, wide soaks up recoil into rubber but kind of bulky with enclosed grip frame
8 Pachmayr Compac Professional, much smaller only two fingers but half of pinky rides at bottom round part, open back on grip frame, feels like a rubber magna with a rubber grip adapter almost
That is my contribution from the bucket o'grips.
Try Ahrends Grips, Altamont Grips, and Badger Custom Grips. They all make good stuff.
