Just a quick correction: The Ruger LC in 9mm is the LC9 (or LC9s or LC9s Pro), while the LCP is only available in .380. As well, The LCR does not come in .380, so I assume you were referring to the .38 Special.
I have recently purchased the LC9s Pro, and can't say enough good things about it. Also, all though it is 4 oz heavier than the LCR, it's exceedingly rounded design seems to make it ideal for concealed carry.
