...The DT 10 and DT11 were and are made in the Beretta Premium gunshop. They are NOT production guns. I have been there and can provide pictures! They are hand assembled the same way any SO is. The stocks are cut and made at the back of the Premium gunshop just like the SO. The difference of European versions are that the stock dimensions are sent in by the gunshop while NA gets a NA standard. Two years ago, Beretta offered custom dimensions at the Beretta day in Montreal, Toronto and Vancouver. In Europe if you have a hiccup with your DT10 or DT11, it goes back to the gunsmith that built it. I have pictures of same! I had a DT10L and is now shooting a DT11. It has similar recoil to my 391 gas gun. It patterns better than my of DT10L with the same loads. It has less perceived recoil than my DT10L. For some, the DT11 does not work and they have gone with the 692. To each his own! BTW, Beretta sent me some flush Optima Plus Lm chokes last year. They patterned much better than the aftermarket chokes that I had! Plus, it made the shotgun livelier. You can order one from Latulipe in Quebec City or Dante in Montreal has stock!
