Welcome from Pennsylvania. I am not an expert in Model 41s, but it appears to me that the barrel was cut very professionally to that length. From what I can see of the front sight it might be secured with a screw and the shape is not right. Just my observation, might there be a barrel length limit for some European pistol match?

Edit: Or it could be a factory field barrel. I am sure some experts will add their observations.
