Welcome to the forum, Miliam...

Virtually anything is "repairable", providing one can shovel enough money at the problem to have it properly done. The technology of micro-welding comes to mind, and I think there is a forum member with either the capability or a good contact for someone who can. Building up the broken area again with TIG welding may also work, if dimensions are cleaned up by machine or hand work after.

This general area of the a Luger is susceptible to damage when using too powerful a load, which may well have happened. The action bottoms out on itself and the frame, stressing and hammering everything. There is an established rumor that Lugers like heavy loads, but this could not be more incorrect! No +p, +p+, or anything marked NATO! Shoot 115 or 124 gr standard loads, Winchester White Box is the go-to round.
