I can remember having a couple of those in the store, but there was a very common rumor (probably from some gun rag) about the slides coming off the frame during firing due to the design of the rails which were intermittent.
Or has my failing memory been thinking of another contemporary German import?
Mud rails are prone to cracking if abused with +P ammo but that was on P226s. Those were only made between 1986-87. IIRC
