Blowback unit return spring and guide.

Does anyone know if the long slim coil spring with the internal guide that fits along one side of the blowback unit in bb autos are all the same. The one in my HK USP is all bent and buggered having been mashed when moving the slide when I hadn’t noticed it was displaced🙈. I can’t find one for an HK but they seem to be available for some 1911s. My USP is still not working, but I can’t further investigate why it’s not firing, cos I’ve damaged this spring. This spring is not the problem with the gun but has been what you might call collateral damage. Many of the blowback units look to be the same or very similar, and at least in the pictures, the springs look the same?
