Merkel 500NE - front trigger first. Will double every time if rear trigger pulled first.
Very interesting. Thank you. Any idea why this would happen?
Two reasons - no interceptor on the front trigger sear (I understand that later models have interceptors on both sears) and the front trigger is articulated (hinges forward under spring tension so it doesn't damage your finger in recoil when the rear trigger is fired) and has a lighter let-off than the rear trigger. When the sears are cocked, if I push the front trigger forward and let it snap back it will trip that sear.
