I recently picked up an earlier Seecamp .32. So far, it works great. Only one mag; the older handmade aluminum style. I'd like a few spare mags, but Seecamp notes that the newer mags will require some sort of modification (to the mag or the pistol) to work properly. Any idea what modification is needed? I don't want to drop ~$50 to find out major mods are needed, and/or just not worth the hassle.
