Unloading the cylinder

7. Interchangeable cylinder

The barrel material used for the weapons with interchangeable cylinders depends on

the law restrictions for the nominal caliber. Precision losses due to compromises are

not to be expected. Occasionally, minor changes in the position of the point of aim in

both calibers may occur. This problem can be overcome easily by selecting the right

ammunition or by adjusting the sights.

The revolver in caliber .357 Magnum is even suitable for the pistol calibers 9mm Para

and 9x21 IMI.

Due to physical restrictions, one cannot expect the same precision as gained with

competition ammunition. Reloading or choosing adapted factory ammunition can yield

major improvements.

For the use of rimless pistol cartridges, we have developed a special extraction

technique. This design closely approximates the use of these rimless cartridges to that

of rimed cases. This is accomplished by a spring-reinforced torsion of the extractor

retaining plate. When

inserting the cartridges into the cylinder, the extractor, which was twisted by about

.024"(.6mm) moves back into its original position.

When the cartridge is fully inserted in the cylinder, the extractor rotates into the rim of

the cartridge shell. With the extractor, rimless cartridges can be easily removed from

the cylinder. Due to the conical shape of the shell compared to the charging holes,

shells of pistol cartridges are loosing their guidance during the extraction process. If the

weapon isn’t held properly, the shell might fall back into the charging holes of the

cylinder during the extraction process. In this event, the extractor retaining plate has to

be fully inserted back into the cylinder. This process might be facilitated by a light

pressure of the finger.

In order to secure optimal functionality, we recommend to tilt the weapon with the

muzzle downward during loading. During unloading, the revolver should be held

oppositely, with the muzzle upwards. This handling is also applicable for typical

revolver cartridges.

The interchangeable cylinders are manufactured as a “pair” and are, together with the

crane, individually fitted into the frame. In this way, we can create the tightest fit with

the lowest tolerances.
