I am a fan of the PT111, because I own one.
But the 24/7 seems to be just a bit larger in the 9 MM.
Length: 6-3/8"
Width: 1-1/4"
Height: 5-1/2"
The Mil Pro pt111 is
Length: 6-1/8"
Width: 1.125"
Height: 5.125"
In the PT145 it is a dif size also it has that kind of difference.
Length: 6"
Width: 1.125"
Height: 5.2"
Everyone says they shoot good, I am still learning. But Size can matter as well as weight if your gonna carry all day and your grip. Single stack, double stack, 12 rds, 13 rds, 17 rd. so there are many things to consider.
