Why?
Howdy Big G...That's an often-asked question. Study it a minute to
get some insight to Browning's mind.
The plunger tube is a pretty thin piece of work on a pistol intended for
rough use. You could even say that it's fragile, and since it's on the
outside of the gun, exposed to all sorts of hazards. If it were integral
with the frame, and got damaged, you'd have to either trash the whole
frame or take the pistol out of commission for an extended period for
repairs.
Reason? Easily repaired in the field. A unit armorer can remove and
restake a new tube in 15 minutes or less.
And now we know!
