Fuzzymcnab the magazines with the yellow follower with the warning to use only in the 4516-1 work in all the variants of the 4516. I have 3 that are my "range only mags". No problems or issues using them in a 4516 no dash, 4516-1, 4516-2 or 4516-3 LE Special order.

Now that said, the only mags that I would use, for serious purpose, in ANY 4516 variant, are the last revision with the black followers. And I change my mag springs in my carry mags every 3 years or 3000 rounds. Cheap insurance to ensure my compact 45s maintain their bet your life reliability. Hope this helps! Best regards, 18DAI
