Just what the title says. We all know what rifling is and what it does, but how does the difference in one manufacturers twist ratio help or hurt their firearms performance? Example: Glock 27, right hand twist at 1 : 9.48in. Ruger LC9, right hand twist at 1 : 10in. The ratio seems to be mostly consistent within any given manufacturer, but whats the real difference here? I am assuming that a tighter twist will grip the bullet harder, causing the bullet to take longer to exit while also allowing for greater powder burn time...? I guess its not really all that important, but I just gotta know! Thanks!
