What is this part called...

[siegersallee]

Thanks guys...now I will sound reasonably knowledgeable when I speak of the "backside of magazine spring catch".

Oh well, it is what it is...

Thanks...I have had no end of trouble trying to explain what I am speaking of in posts and over the phone.

I can now refer them to this post and hopefully, they will understand.

I love this site

Auf zum Sieg!!!
