The .22 "Lugers" are not really replicas - they don't function the same way and the Stoeger Luger in particular doesn't even look or feel like the pistol we normally call a Luger. (Stoeger has owned the name "Luger" as a trademark since the 1920's so legally only Stoeger pistols can be called Lugers.)
Stoeger also sold full size Lugers made by (IIRC) Mitchell Arms. They were investment cast and of only so-so quality and many buyers expressed disappointment.
There have been some better replicas. John Martz converted some original Lugers to other calibers (.45 among them). In the 1970's Interarms got the Mauser factory to obtain the Swiss machinery and resume Luger production. The guns were excellent, as would be expected, but the problem was that they had to be sold for more than surplus "real" Lugers were selling for. Interarms took a financial hit and Mauser pulled out of the deal.
And that is the problem today. Making a Luger, even with modern manufacturing methods, would mean a retail price at least as high as a fair-to-good quality original. No one wants a replica when the original can be had for the same price or less.
