Well speed and weight do enter in to a caliber war , but size does matter no matter how she smiles and says it isn't so . But accuracy is still king of the war . I to feel that if such improvement has been made in 9 it is also available for 40 or 45 , pick what you want and learn to shoot it , internet b.s. aside it is practice and ability any of them and a whole lot of other calibers will work.
Texas by God I to like those smiths and the safety , funny there are some have the magazine disconnect and others do not , some with safety some without and some with both . Actually been on gunbroker and ended up with a couple 40 and 45 , by the time they all come in and I do paperwork and then the background check it will be next month before I get to shoot any of them.
