I have one on a Mossberg 640KD Chuckster 22WMR. The trigger on it is horrible, with no easy way of fixing. The E-Z Pull did reduce the trigger pull considerably. It also introduces creep and it takes up space in the trigger guard. So much space I can barely get my bare finger in there to pull the trigger. On some guns, there is more room and might work out better, but no matter what there will not be much room for a gloved finger and you are going to get a bunch of creep. I personally think you would be much better off doing a trigger job that is outlined in the FAQ. You are going to get a light enough trigger, much less creep and more room for your finger. Good Luck and Good Shooting
