Started with a Daisy BB gun.
Swapped <something> for a Sears Model 1 Single shot bolt rifle, which I still have, 35 years later.
First pistol was 1858 Rem BP, which I still have, 34 years later.
First .22 pistol was a Ruger Mark 1 [$85 new], which I still have, 31 years later.
There have been over 100 bought and sold in many and various calibers, but like the St Pauli commercial says, "You never forget your first..."
