I very much agree with Frank! <img border="0" alt="[nono]" title="" src="graemlins/nono.gif" />
My 1906 AE measures .0015" clearance, and this seems a bit free, in as much as the pin will fall out if turned flange down.
I would estimate that the pin should never be looser than .004" or .1 mm .
39.3701" = 1 meter, .0393" = 1 mm,
.0039" = .1 mm, .0004" = .01 mm
I would not repeatedly fire any Luger with a pin clearance of .2 mm or .0078", Except under Test Lab. Conditions. (which places me in the next room) <img border="0" alt="[crying]" title="" src="graemlins/crying.gif" />

PS: After many trys I think I finally have the figures correct. <img border="0" alt="[ouch]" title="" src="graemlins/c.gif" />
