People rave about the LCR trigger, but it just always felt to me like it took forever for the trigger to reset itself (either that, or it was a very LONG reset). While I've only held one at the local shop, when I pull the trigger as quick as I can, I don't always get the hammer to fall. Does that make sense?
That one gripe asside, the LCR is a fine weapon - I just prefer the S&W trigger. I'm a huge fan of Ruger, but S&W have always been the leader in triggers. Others may not agree, but many will.
