- I decided to make my own .22LR Luger barrel insert and see if a center-fire pistol will fire .22LR cartridges.
I've seen two .22LR Luger barreled extensions [receivers] in the last month, both [apparently] intended to be used with Luger components,
not Erma SE08/2 'kit' components.
So I dug out an old .22 barrel stub left over from some long-forgotten short-barrel conversion and turned it down to fit the Luger 9mm chamber and 4" barrel.
Pics below show progress today.
I'll thread the insert muzzle and chamber it this weekend or early next week.
It will be single-shot, no magazine feed, no extractor, no ejector. Wooden dowel for poking fired [hopefully!] cases out.
