Maybe the FTF and BTF are with New Gen 3, New Gen 4s have finally come to haunt the 10mm frames
Shoot the MTFK with decent ammo and be done with it. Tired of all the sissy whinings, Yes I own a G19 and G26 Both in Gen 4, with no problems. Along with a LWD 10mm LS, G17, G34, G32 ...etc. No I do not have these problems with my Taurus 1911
and it is my most accurate semi auto.
