I find the recoil on the pt145 to be less then some 9mm guns made by others. Have the pt111 but not the 24/7 so I guess I'm no help either. I think MPanova might have some input. Not sure if he got the 24/7 in 9mm yet, was on his wish list. Maybe after Christmas.
Not sure there is much difference between the two. The pt111 is so easy to bring back on target. Can't believe the newer 24/7 has more felt recoil then the mil-pro.
I can't help on the 9mm part, but recoil on the .40 that I have isn't bad, even with the 3.3 inch barrel...I would imagine the 9mm recoil in the 24/7 would be less than the Millennium Pro due at least in part to the weight of the firearms.
I'll be at the range on Saturday, qualifying for my CHL renewal. If they let me, I'll run some ammo through both and report back.....now I just have to remember to take those with me (the toughest part of this assignment).
