A model 65 has been my truck gun for about 4 years now. I paid $280 for off gunbroker. Its not a beater gun but I didn't want a beater. I wanted something that was dead nuts reliable.
If your truck gun doesn't have to be a centerfire gun you coukld always go with a 22 auto or revolver. My ruger single six got me out of a very bad situation many years ago. Its a long story but I think I owe my life to that gun.
