You are generally running a 160-180 gn bullet with 35,000 psi of pressure behind it out of gun with a frame and weight designed around a 115-124 gn bullet with 35,000 psi behind it. It will be different.
Now, even though it is based on a 9mm frame my XD tactical 5" makes the .40 a *****cat. It is easier to shoot than my G-22C .
I can't wait to hear the cries of disappointment from those so eagerly awaiting the XDS in .40. Their is going to be a lot of headshaking as they try to figure out why a 180 gn bullet is so uncomfortable to shoot (at 35,000 psi) verses the ease of shooting the .45 230 (at 24,000 psi).
