The action is machined from 4140-class steel, the same material used in fine big game rifles. The Kimber 17 is really a miniature centerfire, with the firing pin centered in the bolt instead of offset like common rimfires. The bolt body itself is positioned slightly higher than center in the receiver, allowing the firing pin to strike the rim of the cartridge. Lock time is very fast, and the firing pin is strong enough for dry fire practice without damage.
Bullet tips are seated into the rifling without distortion. The bolt face picks up and holds the cartridge under the extractor claw and in line with the bore. As the bolt moves forward a locking lug engages a helical cut in the receiver and gains leverage for smooth closing. As the bolt handle is rotated downward the bolt body moves forward a final .100-inch, seating the bullet.
Mechanics aside, shooting a Kimber 17 is an absolute pleasure. The feel is right and the balance is even better. Life presents few opportunities to own the very best of something.
