I know this is reviving a somewhat older thread, but yes I have the IFG Stock1 in 10mm ...and it is my EDC... after giving it some fluff and buff thanks to videos from the resident SME Memphis Mechanic, I have put about 750 rounds thru it with zero failures... used S&B, Magtech, and Hornady ammo... only real mods are the Henning Guide rod, 22# Wolff Spring...and Dawson FO front sight.
I carry it in an AG Cloak Tuck with CZ-Sp-01 phantom shell... its an exact match for the Stock 1 frame but I needed to use the thicker spacers to get it to fit..
I love this thing...recoil feels like a CZ with 9mm+p.....Enough to sell 2 of my 10mm 1911's that I really have no desire to shoot anymore..
Its a wee bit on the heavy side...good and bad depending on how you look at it...but I was used to the 1911 so it wasn't a huge change.
Hope this helps srrch make a better informed decision if its still up in the air
