Wow, WOW. I never thought id see the day. Now we need reports on it's use. If this is what I think is the cure all for past FTF's and the stronger spring, id might revisit the little bugger. I noticed no compact 10mm's in steel not showing up.
A member here pointed out it MIGHT be a standard mag crimped to hold 10 (look in the center of the body). I will ask and get the dope! 8)
EAA's site still shows 12 round 10mm compact mag's. But they sell full size 10 rounder's which this mag very well could be.
