i just bought an RG model 23 for laughs
I don't think RGs are all that funny.
Seriously, any gun you buy may end up being your self defense gun. When you need a gun, you go for the closest one at hand. If you keep all your Colts and Smiths in the safe, but the RG as a paperweight on your desk, there is a very good chance that RG will become your self defense gun. (assuming you don't have a 12 gauge in the closet of course).
In your defense though, I had a gentleman as a patient who had to defend himself with an RG. It was all he had. It was ugly, the cylinders were crudded up in front of the bullets, and it had electrician's tape for grips, but it worked. Luckily he did not have to pull the trigger.
