I'm planning on buying a 24/7 this year. I already own a PT111. I can't decide whether to buy the 40 or 45. I have a Ruger P944 in 40 cal already but I want a 40 or 45 in a polymer framed gun. I'm somewhat curious about 40 and 45 calibers recoil in a polymer frame; have anyone found this to be a problem?
