Only comment I can make about using an Accro trigger in an Axis concerns a Stevens 200 that its owner had put a Accro trigger in. Stevens and Axis has a different type of trigger spring, but basic design of trigger is similar. As I recall, owner had replaced the Stevens trigger with the accro trigger. He did not replace the complete Stevens trigger assembly with the accro trigger assembly, just swapped out the trigger part. With the accro trigger installed, the safety would not work. Since, the Stevens had been converted into a 6BR Benchrest riflle single shot, owner wasn't concerned about safety not working.
