I'm a big 38 revolver fan, you can get them cheap and fairly cheap to practice shooting. I have them laying all around the house in case the need shows up. The one that goes into my holster mounted on my detector harness is a stainless colt detective special with a messed up finish, I got it really cheap. Not lightweight but functions no matter how dusty it gets. PS a 357 is a better caliber but the only one I have is to big to carry.
