Newbie/village idiot question: the hole in the receiver

[joffe]

Hello guys,

I have both searched the forums using various terms, and looked at detail stripping instructions, schematics, drawings, et cetera.. And I still don't get what that hole in the receiver is for - the hole that is partially exposed when the thumb safety is in the upper position if you have a 'high grip' beavertail. I see no mention of it in the detail stripping instructions, I see no parts using that hole, and I can't see anything particularly descriptive in the STI animation. (note that I don't actually have a 1911 yet nor will I have one for a while..)

I'm sure it's very obvious to most of you, and I will probably smack my forehead when someone tells me. Who wants to point and laugh at the Euro idiot? :D

Who wants to point and laugh at the Euro idiot? :DI assume that your are refering to the hi-capacity polymer and steel modular frames. Looking at STI's website, I'd assume that is the bottom of the cuttout for the arm of the safety. On a stripped frame this usually looks like three holes overlapping to produce a cuttout where the arm of the safety that interacts with the feet of the sear arcs around the pin axis (pin side of the safety being the part that traverses both sides of the frame and holds in the grip safety). In other words, that looks like where the working part of the safety goes up and down.

It usually isn't visible on normal frames with normal safeties.

That is the same hole, yeah. It's only visible on the 'proper' (single stack) 1911 when one begins cutting away at the thumb safety to match it to one of those 'high grip' beavertails.

Thanks for de-numbing my mind - it really was obvious! How else is the safety going to work? :o
