Guide to Kahr Magazines

Loaded Chamber Indicator
This model is designed to provide physical indication if there is a bullet loaded in the chamber. The product is designed with a lever mounted on the top of the slide. The lever is marked as Indicator in red lettering. When a bullet is chambered it pushes the lever upward and out of position. The operator will visually see the lever as it is raised up. Also the operator will be able to feel the indicator as being out of its normal resting position as it will not be flush with the top of the slide, thus warning the operator that the firearm is loaded.

Enhanced Trigger
Kahr’s new enhanced trigger will be featured on Kahr models with external safeties and loaded chamber indicators. The enhanced trigger has a shorter length of pull compared to the Kahr standard trigger. The new enhanced trigger has a 1/4” length of pull with an approximate 7.5 lb. trigger pull weight compared to a 3/8” length of pull for the standard trigger. The trigger pull weight for the enhanced trigger is the same as the standard trigger, approximately 7.5 lb. 

External Safety
This model has, in addition to the internal safety, an external safety that will prevent the firearm from firing when the safety is in the safe position. The product has an external lever with two settings. When the lever is pushed completely up and the red dot is fully visible, the firearm is in the armed position and ready to fire with the pull of the trigger. When the lever is pushed down, and the red dot is hidden the firearm is in the safe position and will not function with the pull of the trigger. The safety works in the following manner. When the lever is in the down (Safe) position the connecting cam on the lever pushes the trigger bar out of position, disconnecting it from the cocking cam. If the trigger is pulled in the safe mode, the cocking cam will not release the striker and the firearm will not fire. When the lever is pushed up (Fire/Armed position) the cam moves out of place and the trigger bar moves up, again connecting with the cocking cam. The firearm is then ready to fire with the pull of the trigger.
