Magazines and holsters for the original Shield 9mm and the new Model2.0 appear to be interchangeable. The only perceptible difference in the 2.0 magazine is that the 8 round mag has stippled surface that matches the new more aggressive grip on the Shield 2.0. I have and use both, with a two different holsters (Milt Sparks VM 2, Vedder Lighttuck). And the original Shield 9mm mags, while they don't have the stippling, not only work fine, they are $20 online (Brownells), vs. 29.99 for the Model 2.0 mags (DEGuns).
