A 955 TS first

That would create the opposite effect. Less pressure on the front of the bolt and harder hit of the rear of the bolt against the stock. IIRC, on my monkey stocked 9mm, the bolt hits the stock before the spring is fully compressed.

 

Which is the new and which is the old? Mine is a combo of the two!!!

 

Thanks
Is the raised lug at the front of the new style bolt extra material thus providing extra strength to the bolt OR are the fronts the same thickness, but the new bolt steps down at the corners. It's hard to tell the actual thickness in the pics.

I guess my bolt is a Gen 2. It is dull grey.
The top looks like the early, same logo and sight screw clearance cuts.
Has the internal cuts for the LRHO.
The front is stepped like the new style.
Does not have the round cut in front of the charging handle hole on the LH side.

 

Great!
