i have a couple of b.a. derringers and a variety of barrels. if your budget is tight there are better choices. that said, the ability to change barrels makes them useful survivalist pieces, they are built to be enjoyed by your unborn grandchildren and used ones can be had cheap.
some advice: if buying used get the upgraded version, denoted by indented trigger and wide hammer spur. ditch the wooden grips for rubber grips, definitely large for “4” calibers. use only handgun specific 410 ammo, your wrist will thank you. start with a 410/45lc and quickly add a barrel in your favorite handgun caliber, either 38sp or 9mm is actually pleasant and cheap to shoot. an open trigger version is handy if you live where where wearing gloves is required in winter.
