A friend asked me to bring my m1-9 to the range so he can see what the problem is. I've had the same issue as most, FTF regardless the ammo used and even after the 500+ round break in period. He had a stack of pro mags w/ him along w/ a genuine Bertta 92 mag. We tried his Bertta mag & Pro Mag....NO FTF. Then we tried the pro mag that came w/ the rifle, several FTF. So the rest of the morning used a variety of ammo in His Beretta & pro mags....NOT A SINGLE FTF!!!!! So looks like I will be ordering some Beretta/Pro Mags magazines. Finally, I can enjoy this fun little gun.
