I guess that is what you would call a pistol that you want for personal defense that you don't mind dropping and getting dirty. I do a lot of mountain biking and trail running and wanted to get a pistol that was durable, reliable and I didn't have to pay a lot for since it will get banged around. I bought a Sig Sauer SP2022 in 9mm. I also bought a 5.11 holster that attaches to the molle straps on my hydro-pack so it will be within quick reach if I come across some coyotes or mountain lions.
I was trying to look at what else would make a good beater gun, but I couldn't think of anything else. What have some of you chosen for this type of task?
