I carry the std version of this in my LCR, and it's what's in the Model 28 on my bed-side table. I haven't been able to find any of the +P around here, just the std. 38.
Looking at the ballistic specs on the Hornady site, there really isn't much difference between the std 38 Critical Defense load and the +P. Standard is 1010 fps from a 4" vented test barrel and the +P is 1090 fps.
