My wife has a BG380 and we haven't had any issues. But, if you don't trust yours by all means pick up something else. I think everyone needs at least four or five carry guns. For the record, I love my Smiths but I value lots of different guns.

The 642/442 would serve you well, but if you wanted a wheel gun why not pick up a 357 such as the MP340 or others. You can always practice or carry the 38 specials if the 357's are a big issue recoil wise. You mentioned Kahr, not a bad choice. The PM9 with the 9mm round would in my opinion would be a better defensive choice than a 38 special. However, you can likely get into a light weight 357 for not much more. I recently shot the LCP with laser, wasn't bad. I do prefer the BG trigger and sights. But, afterwards I did look at the LC9 for kicks. Could be a fair option, 9mm, light, safety.
