Does anyone know if the Sig MPX is any easier to rack then a standard AR-9? My kid enjoys PCC, but my gun is 1) not lefty-friendly and 2) finds it really hard to pull back on. Some of that is him being weak, but some of it is that the recoil spring is genuinely pretty stout. (OTOH, it works 100% of the time, so no intent on changing it out.)
