I have a Walther Model 4 that I would like to plink with some but also be able to conceal carry. However, the hammer on it was broken and was repaired by putting a screw in it by the owner before me, which no longer works. I've been looking all over the internet, tried Numrich, Gunbroker, even called 2 places in Germany but have not been able to locate a hammer and hammer roller. If anyone has any leads where I might find or is willing to sell one please let me know. Any help is appreciated. Thanks.
