I just love the emotional rants without any objective feedback on the firearms themselves - hence take emotional rantings with a grain of salt.
It gives an impression of having no significant seat time behind the firearm itself. Using personal experience or an isolated example instead of a valid argument, especially to dismiss statistics. ie: anecdotic.
ANyhow - as far as a XD, M & P and a Glock in case anyone cares for an objective input:
The Glock has a lower bore axis which makes it a little better of a shooter for most but the XD/XDM has a grip angle that some prefer over the angle of the Glock, however either one can be learned to shoot just as well. ( note grip angle differences with pic) ...NOTE - as previously mentioned - I have no brand loyalty, I happen to own these handguns and use them when I can.
The M&P is a very similar pistol to the Glock with again a different grip angle. Using both shelf ammo and reloads on all my pistols the Glock tends to have better recoil management ie: less top heavy than the M&P but that may not be a good thing depending on the type of grip you end up using.
Proper trigger manipulation is key to accurate pistol shooting – some like me argue it is the most important factor when learning to shoot a handgun. For this reason alone trigger characteristics and pull weight deserve careful consideration when selecting a#pistol - having said this - Ive changed all my triggers(as to only my striker fire pistols) to 3.5lbs of pull.
Stock trigger pulls are: Glock 17 its 5.5lbs - M&P : 6.5lbs - XD40 - XD9: 5.6lbs
