Does anyone else make reliable feeding 10 round 7.62x39 mags?

Model 1 Sales offers a reliable 10 rd. 7.62X39 mag.  I currently own 5 of them and, just as long as you don't get greedy and try to stuff extra rounds into the mags - you can actually stuff 2 extra rounds into these mags - they're great.  The mags'll FTF every run through if you get greedy though.  I experimented and found that I'd get at least 2 FTF's with each leading of the mag when I tried to get 11 rds in, but that they'd function flawlessly with 10 rds.

All this said, I'm still waiting with baited breath for Larry's 25 rd. stainless 7.62X39 mags!!!
