If you just like and want the feel of the Luger but in .22 LR, the answer is simple - buy a Ruger Standard Model. It will look a bit and feel a lot like the Luger but will be reliable and be fun to shoot.
There are only two (AFAIK) .22 pistols that use the toggle link action, except the Luger conversion kit (and one of those will really cost money!); those are the Stoeger Luger and the Erma pistol. I have shot and worked on both and can't really recommend either. They were made for no other reason than to make a toggle link pistol that resembled the famous P.08. They were not reliable and had many problems, some of which, to be truthful, were caused by owner attempts at disassembly.
