Is the Eemann slide stop legal for USPSA Production?

[matteekay]

This thing is obviously a thumb rest masquerading as a slide stop:

 

 

 

Equivalent offerings for the CZ and P320, etc, are approved for use because they're still functional slide stops and/or takedown levers. I'm guessing this would be legal since it still works as a slide stop? Has anyone checked?

This is a two part question

 

1. Is it an external part mentioned in Appendix D4 section 21.6?  Yes: proceed to question 2.  No: part is not legal, forget about it.

 

2. Does the pistol still fit in the production box?  Yes: you can use it in Production, No: you can't use it in Production

So... have you tried it? I think it'd fit but confirmation would be great.

Nope

 

I was just answering to their rules legality.  One-piece thumb rests that replace pins or slide stops are always legal in CO regardless of size because CO doesn't use the production box.  A mistake IMO.  The IDPA CO box has a slot on the top for the optic to protrude and that's exactly what we should have done

 

Personally I don't see the point of thumb rests like that one.  Every one I've tried in someone else's pistol has been too far back to let me build my grip how I want.
