I just wanted to thank everyone for their input regarding my previous thread about carry options(due to my knee injury).
After reading all the responses and trying out the feel of a couple new guns and holsters I decided to add a new firearm to my collection!
I now have a S&W 638 with a pocket holster. It works great and stays concealed easily.
Thanks again everyone!
On a side note/question -- anyone know a place to get a great deal on Crimson Trace grips for this? The best price I've found thus far is $240.
