I own an LCR and do like it.
One slight negative for me is born out of the fact that I'm used to shooting autos with the reset method. So, when transitioning to the DAO LCR trigger, there is the possibility of short-stroking the trigger so the gun binds up until I let the trigger out fully. This is potentially incompatible with a rapid-fire scenario. Just something to be aware of. I've cured myself (mostly) by practicing dry-fire.
If I had a do-over I might opt for a j-frame sans the internal lock.
FWIW, the ruger does also have an internal lock.
I'll try anything twice
