Got an email on these the other day. Was excited till I realized I had already wasted $80+ on 9mm Wilson mags for my Defender. Really like the .45 Wilson mags but I don't know if I'll ever trust the 9mm mags again.
I like these. Been shooting the original ETMs for a good while in Steel Challenge and other gun games with great success. Never had any issues with the spacer or anything else for that matter - so far. While I have no idea what a 'Vickers mag' is, I am patiently waiting for the Havanajim Competition 9mm ETM - an extended single-stack mag, 14-round capacity, thick impact-resistant baseplate, witness holes for all rounds. The extended portion having slight serrations fore and aft for grip. Also a small, slightly recessed rectangle near the base at the spine for the included, custom numbering stickers. Once can dream, right?
