Springfield has introduced a compact version of the XD(M) pistol called the 3.8. Its name refers to the barrel length which is 3.8" long, 0.7" shorter than the standard XD(M). The name is sure to confuse many who will think it refers to the .380 cartridge. The 3.8 model features non-slip slide serrations which have a kink in them, unlike the standard model which has straight serrations.
