The P5 Compact locking block looks pretty robust in comparison to the 92FS. That being said, is there an expected service life out of this locking block? Would it be wise to have a spare locking block if it's shot often? Or would the pistol frame crack way before the locking block fails? (as mentioned on this forum)
Any interchangability to the other Walther locking block pistols or is this a proprietary part unique to the compact?
