As I pointed out earlier, the 240 magnum breech seal is not a problem 3 blobs of superglue on the underside of the seal solves the problem. Mine has been like this for donkeys years.
I own examples of both the 240 and the 45 and they are both excellent pistols for different reasons. Can we just agree that each pistol is the best spring powered pistol that WEIHRAUCH/ BSA have ever made. Please do not mention the Scorpion as this is just a short rifle with a pistol grip.
