Best Lugers for rebarrel / custom calibers ?

[lfid]

postino , Hugh , thanks for your comments

I think for customs with rear sight that a silver soldered base on toggle plus a locked down windage only rear sight would work as soldered base seems to be the case with the Dewey custom lugers that were mostly all 9mm. There seems to be no reported failures for the Dewey rear sights.
Elevation would be in front sight likely with replacable blades easiest method

For longer barrels I think the sights both on barrel and windage and elevation in rear but still with a replaceable front blade , like the Wyatt 45 Lugers

Breechblock would be original but with cartridge pocket cut to larger diameter , extractor and ejector sightly relieved as needed

Agree wildcats also cool, likely use optic sight mounted on the left side frame flat
Wildcats with long barrel say 10 to 12 inches

And so far I have found best original trigger pull to be a two stage but crisp break at 4 pounds
But expect to be able to improve on that mix and match experiment

Thanks for all comments !!!
Bill
