Bibbyman!!
How on earth can you be critical of the "Two Notch" cylinder base pin??? That base pin is designed to keep you safe after you load up with 6, climb up on your step ladder and drop the gun on it's hammer!! We all do that at least once or twice... RIGHT!!
Second thing I do after getting the current crop of SAs out of the box is cut the last - or first - depending on your point of view, 3/16 inch off the base pin, then bevel and polish the end. Then you can shove it all the way in ALL the time. Although, after the modification, you will NOT be able to load up 6, go up on the step ladder and drop it on it's hammer. Bad Ju Ju.
