I must be mistaken then. Maybe I checked on the FAQ page of their website, but I am 99% sure I read it from a SA official source somewhere. I like having a little more pressure for a short barreled gun, but always get word from the company first. My full sized guns get standard pressure ammo.
Just for informational sake, I found my XDs to hit POA most consistently with 230 grain ammo. Lower weight ammo hit low as expected, but also produced a lot more muzzle flash than the 230 gr ammo.
I agree, the gun carries great, especially in a hybrid IWB holster. I forget I'm carrying it. I'm also consistently impressed with the accuracy of that little monster, and was really surprised the first time I shot it.
