I was hoping you would 'weigh in', Kuduae.

Your depth and breadth of knowledge on these matters far exceeds mine.

Stoeger, however, did list the "British style three leaf sight" on all of their 'High Velocity' offerings as standard equipment on the 1939 page above.

That is very interesting to know about the difference in magazine between the '24 and the '25, as well as the stock difference.

The stock forend on the rifle image you just posted rather resembles that of the takedown version.
