Hi flint -
Yes, it's 15/32", (.45 ACP) but note the conditions of the measurement - with the slide locked back, from the face of the slide.
And it ejects properly except for the last round.
Since the 1st post, I've found that there are various length ejectors available, w/compacts (his Kimber, e.g.) normally having less protrusion, and that length/nose-shape "adjusts" fired-case ejection angle & distance (which has been very variable w/mine, possibly because the factory ejector has a flat face).
So now I'm pretty sure that ejector length is not the primary issue, 'tho it may require slight adjustment in the future, as I do get a slight "nick" on case mouths, which I now suspect indicates slightly early ejection.
Thanks for the reply.
regards,
