I purchased a .38 LCR a few months ago. I have a S&W Air weight 438 as well. The Ruger is slightly lighter. They are comparable in size. The S&W has a bit better build quality, IMHO. The Ruger does have a trigger bar rattle when shaken. I have been carrying it for several weeks. Honestly, don't even know it's there. Because of its size and weight shooting +P is a bit sporty. A box of 50 and the had starts to hurt. Group size is adequate and should improve once I'm more used to the trigger. Out of the box the Ruger LCR really doesn't need many improvements to be made. My S&W got a new spring kit straight away. The Ruger trigger is really smooth and crisp. Overall, I'm happy with the revolver. When I need a light weight platform I carry the LCR. When I go downtown, it's clearly a Glock day.
