The trigger on the LCR is designed to be completely released into a full reset position before it is depressed again. You may short stroke it 100 times with no problem and it could break on the 101st time. I can tell you for a certainty that is what happened to mine. Afterwards the cylinder would not lock up and the trigger pull felt like somebody poured sand into the action.
Ruger replaced the entire trigger ass'y and test fired the gun before returning it (and paying shipping) under warranty. Although I still carry it I do have a concern that, under stress, using a DAO piece, that it would be easy to recreate the failure at a REALLY bad time. I alternate carry with my Taurus 851 .38+p and that weapon is a brick; a nearly indestructible, tack driver regardless of the Taurus-bashing that often occurs here.
