The very best pedals I’ve ever had, were Gusset Slim Jim magnesium ones. Never had a pin fall out and they are totally serviceable. Eventually the pins will wear, but can be replaced . Unfortunately I have retired mine for the time being as by the time I got to servicing them for the fifth time in about 6000 miles, I really did need a new pair of axle pins and I over tightened the nut on one , in an attempt to take out the last tiny bit of play and stripped the thread.
That said though, light, easy to keep running like new and no pins fell out, or, come to that wore out. Just not certain they are still readily available.
