I bought a new model 29-10 last summer it has the lock system but other than that it looks just like the 29's of the 1970's. if you have the opportunity to buy a new one i would definitely go for it. I absolutely love mine and it the envy of all my friends. The only thing you may not like is the grips on the new 29's. they are much narrower than the grips on the old models. I bought vintage grips for mine and it is great very comfortable to shot. Go buy one you will love.
