I’ve a quick video of a comparison shoot between the AF-S15 and the AF Attila.
Note that I’m aware that this isn’t a fair comparison, as one gun isn’t optics-read and the other has an optic (that will greatly affect shooting results, as you can see here).
This was at 10 yards. That’s not a long distance but I’m shooting at small targets. The S15’s hits are on the left and the Attila’s hits are on the right. There’s 15 shots per target.
I’m able to shoot the Attila faster and be more accurate, mainly due to the optic, but probably really due to a culmination of new updates that the Attila has that my particular S15 doesn’t. The results might differ if I had an optic-ready S15.
