I have been EDCing a Q since 2011 both personally and professionally. Because of an injury I must manipulate and fire my weapon one handed.I've tried both and neither offered an appreciable reduction in recoil.
I have tested both as well. With the Sprinco system (yellow spring), my Q5 "settles more quietly" in a split second, as compared to with a one piece rod and 13lb spring, if that makes sense. With the latter, my red dot moves and settles more violently (kind of wobbly for a lack of better term). I guess that it is because the slide hits the frame harder at the rear end??I've tried both and neither offered an appreciable reduction in recoil. I have found using a non-fixed stainless steel guide rod and tuning the pistol to the load through varying spring rates to be much more effective for a competition gun. For a defensive weapon I personally prefer to use factory spring rates to ensure reliable feeding.
