A link to what you're discussing would add a LOT of clarity to the conversation.
Once upon a time Cajun Gun works had two short reset system part kits in stock: SRS-1 and SRS-2. At the present time only SRS-2 kit is offered.
I received a gun with unused SRS-1 kit included in the box. Planning to use it, therefore my question: what is the difference between most current SRS-2 kit, and older SRS-1?
Hope that adds SOME clarity.
