Don't necessarily give up on the LCR yet. My wife and I bought matching LCRs with CT grips. I'm a good size guy, but my wife is very slim/tiny and has also had carpal tunnel surgery in the past. That said, she loves the trigger. It really does feel different than other snubbies (I also have a S&W snubbie which is good, but we like the LCR trigger better).
The easiest way to explain it is that your finger does not feel the weight until you are in the power zone of your finger strength (ie, pressure is light when your finger is extended and then builds as you pull). Being a range rental gun, you may have gotten a beat up example, dunno. Also, while I'd think the Hogues would be better, the CT grips on ours have never been an issue.
Anyway, we are both very satisfied with ours and I'd buy another one in a flash if something happened to one of ours.
You may also want to hang out to see how S&W does with their polymer snubbie, but I don't think it has hit the streets yet.
