Боевая пружина - не пластинчатая (с возможностью регулировки), а обычная, витая.
для неупертых целевиков - этот момент несущественнен.
все остальное - Смит и Вессон... те же яица - вид сбоку...

Усилие витой боевой пружины на средне- и крупноразмерных таурусах регулировать можно.

ADJUSTABLE HAMMER TENSION AND TRIGGER STOP
Taurus Silhouette Target revolvers are equipped with adjustable hammer
tension and trigger stop. When adjusting, make sure the firearm is
unloaded and always keep the muzzle pointed in a safe direction. If
possible, leave the cylinder open during adjustment.
WARNING: These are sensitive adjustments and should be made
carefully and in small increments. Proper tools should always be used.
If you are not comfortable with these adjustments or unfamiliar with
them, then do not attempt them. Improperly adjusting these settings
can create a hazardous situation that can result in damage to the
firearm, accidental death or serious injury.
Hammer Tension Adjustment
WARNING: The Hammer Tension setting is different for single-action
and double-action shooting. Attempting to shoot double-action with the
tension set for single can result in failure to fire, and may create a
hazardous situation.
WARNING: Some brands of ammunition and primers require harder
firing pin impact than other brands. Caution should be exercised when
adjusting the hammer tension so that the setting does not result in a
firing pin strike too light to ignite the primer. This can create a failure to
fire situation which may be hazardous.
WARNING: It is possible to set the hammer tension too light to reliably
fire the cartridge. This can result in a hazardous situation.
To adjust the hammer tension, remove the
grip by loosening the single screw on the
bottom of the grip and pulling it free from the
frame. The adjustment knob is in the frame.
Use a small flat bladed screw driver to hold
the inner bushing and turn the outer bushing
to adjust. Turn clockwise to loosen the
tension and counter-clockwise to tighten. The
tension can be checked by verifying that the
firearm is unloaded, pointing the muzzle in a
safe direction and ‘dry-firing’ the revolver.
When the hammer tension is adjusted, replace the grip and the grip screw.
Trigger Stop
WARNING: The trigger stop can be extended to a point that prevents the
trigger from releasing the hammer to fire the cartridge. This can result
in a failure to fire and create a hazardous situation.
To adjust the trigger stop, remove the grip by
loosening the single screw on the bottom of the
grip and pulling it free from the frame. Loosen
the trigger stop set screw. Make sure the gun is
unloaded, point the muzzle in a safe direction
and cock the hammer back. This will bring the
trigger to the single-action stop position. Using a
needle-nose plier, gently move the trigger stop in
or out to the desired position. Allow adequate
travel for the trigger to release the hammer and
fire the cartridge. Tighten the set screw and replace the grip and grip screw.
WARNING: Under no circumstances should you attempt to fire the
revolver with the grip removed. Attempting to do so may damage your
firearm and may result in accidental death or serious injury.
