I went to the range the other day to site in my Marlin 60 and you know I can't go to the range without taking the twins along. After getting the .22 sited in and knocking a golfball all over the place with it I pulled out the Steyrs. I put 100 rounds through the S9 and 50 through the S40. After it was all said and done I noticed that I'm just as accurate with the S40 as I am with the S9, but I tend to be able to accuratly follow up a half second faster with the S9 vs the S40. So here's the question, would you carry something that would hit harder like the .40 or carry something that would allow for slightly faster follow up shots?
