 Taurus GX4 XL. 3 inch barrel with the original GX4, 3.7 inch barrel with the GX4 XL. It's a 13 round mag and 11 round mag additional back strap. They like the longer barrel for velocity. They like the longer barrel for accuracy and you're gonna get that. It has very nice grip texturing feels good on the hand with this 13 round mag you get three finger contact forward serrations does have a sight hole indicator there pinned in front sight serrated black adjustable rear sight neat looking trigger guard there kind of hit that 90 degree angle it did a nice job and they kept the same trigger now I measure this trigger right at 5 and a quarter pound flat trigger nice crisp break
