This conversion is a simple recoil spring and barrel swap.

The design also allows the recoil spring to be placed around the barrel making for a shorter profile gun.

In the late 19th century, the dial was refined to be operated by a recoil spring and centrifugal governor.

This is only possible with a heavy slide and strong recoil spring.

The bolt is released and forced closed by its recoil spring, chambering a fresh round.

The repeated shots rocked him back an inch or two, but the recoil spring ate up most of the kick.

The recoil spring was also updated in late 2010.

When field stripping the Ace, the recoil spring is removed after removing the slide.

Then the recoil spring and its guide fit in back of the bolt carrier.

The barrel is then driven back by the recoil spring to load the next cartridge.
