So I live On the border Of Massachusetts and Rhode Island and I want to get my non-resident Ltc in RI.To do this you need to qualify with Whatever Firearm you want.However, say If you qualify with a .40S&W that means you can't shoot anything higher than a .40S&W...So my question is, what caliber in RI do they consider the largest? Is it determined by mass of bullet?velocity?Recoil? Anyone I ask don't know this Question(including A Tiverton,RI officer lol) is .45 bigger than 10mm for qualifying?trying ro qualify with the largest gun round possible...any info would be awesome!
