Bought a Miroku Daly 20ga for my grandson about a year ago. Only problem with that gun was difficulty in opening once fired which was solved with a diligent cleaning of the chambers so I can't blame that on the gun. It is a little heavy for the gauge but a 13 year old can use the weight to limit the recoil. Question about stock length: the butt stock length as original seems to be a bit on the short side. About 13 5/8" to the rear trigger. Is that common on these guns?
