The COILED pin would be much stronger, and preclude use for snap caps, and probably be easier to remove when you needed to do so. The trouble with a single roll pin is that it is weak, and because of the base of the slide, is hard to drive out. I have thought of inserting a SMALLER single roll pin like CZ and SIG do, but when you go to drive it out, the outer pin may get stuck.
