Hello everyone outhere: Im new to this forum but not new to glock, Im been told that for smaller barrels like 3 in or less the faster the bullet like 115 maybe 124 are better but the 17 is 4,49 will this help the heavier 147gr bullet to develop enough punch power? The other issue that have call my concern is that on the glock web Sgt, Gunny mention that he does not understand why the Gov has gone for over 25 yrs with the 9mm he is a fanatic of the 1911, wich Iknow is a very honorable equipment but especially he mention that one torso shot of 45 is 100% guarantee to stop an assailant vs maybe 3 of 9mm what is this gentleman talking about? 75% of the world carry and use 9mm guns not only cse price,availability,weight,placement and last assortments of weight and bullets can anyone tell me should I trow away my 17,pps and mpc9mm, thanks a lot.
