I bought a PFS for my 682 Beretta in 2008 & it was the "new style" but I don't know when the change was made. The one difference I noticed was that the anti-rotation rod, or top rod, is thinner on the new model, 1/4" vs. 3/8". I think I would prefer the thicker rod because the one on my gun seems to flex downward when firing the top barrel & straighten out when the unit rebounds, causing a slight cheek sting. John
Glenn, I think the cast on/off feature that Pat is referring to is the fact that there are two 1/4" holes side by side in the main block that attaches to the grip that allows the upper rod to be located either right or left, depending on the desired cast. The block is not wide enough for two 3/8" holes, hence the change to the 1/4" rod. The 1/4" rod has a cross sectional area reduction of over 40% which may account for some loss of rigidity. John
I shot the old style for a couple of years. Now I use the new style because I can raise the poi to my preferred height. With the old style I had to find screws that were longer to go higher. I don't need cast off or on so I am not a contributor on that. Over all, I think the pfs is superior to all other recoil reduction systems because of the infinite number of recoil settings and the precision you can set poi. Having said all that, I still can shoot some really crappy scores. George Miller
You are right Jim, BUT, the difference is less recoil to the face with offset. With offset the comb is moved over from the ribs centerline, but IS IN A STRAIGHT LINE WITH THE RIB.
Cast off or on is just bending, shimming, or angle trimming the stock to the receiver to move the comb over, this results in the front part of the comb bumping your cheek upon recoil. Over a long day or week this can cause discomfort and cause the shooter to begin to lift his/her head to avoid the bump.
I first learned of offset from Dan Bonillas in the early 80's and have had all my stocks built with offset ever since. I use approx. 1/4 inch offset and 1/2 inch toe out.
Just trying to help you shoot better with more comfort.
Gil,(George) you don't shoot crappy scores to often.
George, I not just exactly sure who first showed me the "dime" adjustment but it works. With the old style, I place a dime between the grip & the stock at either the top (above the connecting bolt) or at the bottom (below the bolt, in the grip) depending which way you wish to make adjustment of the comb higher or lower. The only other thing I added was a tapered pitch wedge at the butt. Had far more adjustment then I need. Moved my pattern to 100% and best recoil reduction you can ask for.
