Gerry -

John Sabato was kind enough to post a 'sample' of his CD pictures in one of his albums, which comes up frequently in the Random Album Pictures -

I've done about a dozen Luger threads since the 70's/80's, all 60º. But where I differ from the SAE is that I do not adhere to the 75% thread depth. I make my [male] threads 100% thread depth and then just kiss the apex of the thread with a file. Also, I want my threads to be a snug fit, not a 'running fit'. There are different classes of fit, but the fit you find on commercial threads here in the US is very 'loose'. I've had no problems with my snug, pyramidal threads. Even when mating with German/Luger receivers.

There is some variation in tolerances in Luger receivers. If you make your production run somewhere in the middle, then some will be tight fits and others will be loose fits.

Regardless of how or what you do, there will always be someone somewhere who will complain about it.

You can and you can't
You will and you won't
You'll be damned if you do
You'll be damned if you don't.
