Here is the deal, I got two brand new Mec-Gar magazines(in a trade) (supposedly for a Taurus 92), they are not for a Taurus 92, or 24/7 or PT100.  They are marked Taurus by Mec-Gar.  The funny thing is they are identical in every way to the P11 10 rounders except they have a metal flush floorplate and the mag catch is just a hair too high.  Because the mag catch is too high, they don't fully insert, they miss by 1/4 inch but if you depress the mag catch button and push them flush, the fit is perfect and operates the BHO.  I have contacted Mec-Gar but their techs were out at a trade show today, they are supposed to call me back.  They don't even know what they are for.  I am hoping for a small fee they will send me P11 mag bodies, that would be ideal and I would have two flush fitting 10 round mags  .  I was almost completely pumped when I initially looked at the mags to compare, then a click 1/4 inch shy of full insertion

Yep, that's it, except the enigma continues:
 
"Taurus 9 mm 10 round magazine for a compact model. I do not know what model it fits so look it over and see if this is what you need. Shipping $6.00
 
 
 
Maybe a PT111 Millennium Pro???

Get a friend with a TIG welder to fill in the slot and cut new ones. Problem solved

they are likely PT111 megs.  Of you look at the Pierce pinkie extensions for the P-11 KelTec, they also fit the PT111 Taurus.  Must be same floorplate, same mag body floorplate lips and likely same magazine dimensions.
