Semi-Auto Selectors = "F" to load?

[Centerline]

Both the Action Arms and Vector semi-auto UZI Carbine manuals indicate to position the semi-auto selector into the "F" (fire) position when loading/charging the firearm... and then move the selector to "S" (safe). I'm sure there is a simple answer, but why on "F"? Most any other firearm, including the full-auto SMG versions of the UZI have manuals typically indicating to have the selector on "S" (safe) while loading/charging. Why can't or why isn't it recommended to have semi-auto UZIs on "S" (safe) when loading/charging? Thanks...

I think because with it in "S" it wont load. When its in S the grip safety will not release the bolt.

When the safety is on S, the sear wont go down at all, not allowing loading, charging the weapon.

Roger that, figured it had to be a simple answer. Thanks to both for the info.

That explains the mechanical part, what about the REASONING part of the design?

I agree the reasoning doesn't make much since from a safety standpoint, but...

Perhaps because the semi auto Uzi variant made for the US. market was derived from a select fire subgun? Semi auto versions of full auto guns often leave a lot desired.

Makes very good sense for open bolt, but should have been redesigned for closed bolt. Try to remove a round from the chamber on a closed bolt. Remove the magazine, squeeze the grip safety and try to pull the slideback without accidently pulling the trigger. Very easy to happen, had it happen to me.

SO: I got to thinking what would it take to redesign the open-bolt design. Thought maybe cut off the side of the sear that doesn't do anything, the firing pin is all that is needed. But found out it doesn't matter. What makes it necessary to have the selector on FIRE is to let the fireing pin be retracted. If the firing pin is already retracted and cocked the grip release does not need to be squeezed. The bolt can be pulled back far enough to extract the round ( or even insert one from a magazine ). I scanned the page from the UZI model A semi-auto and made my changes to it.
