As the article correctly stated, the 40 S&W was originally designed around a 180 gr. bullet @ ~950 fps

Compared to some of the lighter bullet loads, the standard 180 gr. may produce less recoil, advantageous for control / follow up shots especially out of compact pistols.

All of this data is based on an average of at least 5 shots from a Glock 27

Harder kicking 40 S&W loads:
Glock 27: Ranger T 165. @ 1,116 fps = PF 184
Glock 27: Speer Gold Dot 155 @ 1,171 fps = PF 182
Glock 27: Cor-Bon 135 JHP @ 1,332 fps = PF 180

"Softer" kicking 40 S&W loads:
Glock 27: Remington 180 HP @ 945 fps = PF 170
Glock 27: Remington 165 GS @ 1,018 fps = PF 168
Glock 27: Federal 180 gr. HST @ 930 fps = PF 167
Glock 27: Federal 155 gr. HS @ 1,072 fps = PF 166

PF = power factor and it is useful for quantifying recoil out of same size pistols.
Bullet weight x bullet speed / 1,000 = PF

I have shot plenty of 180 gr. 40 S&W ammo and never had a problem, have 180 gr. HST in my 27 now.
Regardless of bullet weight, don't chamber the same round multiple times - avoid set-back.
