Not the three most practical, most effective, or most expensive. Just the three that I'm digging at the moment. Of course, this list is subject to change, and will quite frequently.
1. S&W 442 no lock
2. S&W Model 36 police trade-in
3. S&W Model 10 police trade-in
Don't know how I ever became such a wheel gun fan, growing up in the age of the Glock. My friends roll their eyes when I suggest they pick up those great 269 dollar buds police trade-ins.
