Important Installation Note:

This mainspring housing is manufactured to precise WWI specifications. As such, it may sit slightly proud or below the frame on some pistols, requiring the frame to be blended to the mainspring housing for a perfect, seamless fit. This process, often performed by a qualified gunsmith, allows for a customized and exceptionally well-fitted result, eliminating gaps and ensuring a smooth transition between the frame and the mainspring housing.
