The invention discloses two related improvements over existing trigger mechanisms utilized in pneumatic launching devices--such as pellet or paintball guns. The first improvement is a method for allowing a single trigger frame configuration to be utilized by a multiplicity of launching devices despite differences in attachment points and/or mechanical linkages inherent in the same. The second improvement relates to incorporating a trigger return mechanism within the trigger frame which utilizes magnets, pneumatics or mechanical means to actively return the trigger to its initiating or `rest` position after it has been operated.
