The primer was located towards the base of the cartridge, but completely internally. The pin, shaped like a little finishing nail,
pointed on the inside end and resting on the internal primer, projected radially about a quarter-inch to the outside of the base of
the cartridge. When loaded, a pinfire gun showed the tips of the pins exposed through small slots in the tops of the breech faces of the barrels.
To fire, hammers fell on the pins, driving them (through the wall of the cartridge) into the internal primer.
A steel ring, around an inch in diameter, mounted to a stud, usually on the left side of the receiver of a carbine,

Assuming a right-handed shooter, the right arm is punched straight out, while the left elbow is bent and the left hand pulls back to provide tension. As a result of this change, Chapman gets its stability
from both muscle and skeletal support. This makes it a little more friendly than Weaver for those who lack upper-body muscle strength.
