I purchased one of these a few months ago. I could never get a good sight down the barrel without getting smacked in the cheek. Had it out the other day,put a 3" #2 shot in it and wham it broke. The spring in the pistol grip let go. The stock covered about half of the trigger guard hole? Now it just slides back and forth freely. Needless to say it is going back to Cabelas. I used it on a Mossberg 500A. I am on the fence about getting another pistol grip stock. I will switch the wood out when I go trap shooting,but would like to replace the knoxx with something that has a better comb for looking down the barrel for HD. Any sugestions???? Joe
