Alright I'm 6'8 320lbs, I like guns with some power. But having said that I have also wanted an FNH 5.7 for a while.I have a Glock 21sf .45 but the recoil makes it hard to keep shots accurate so I don't knowwhat a good caliber is for me. I would like a revolver like the Judge or something similar that can shoot.45's or 4/10's as a back up but something that will hold some rounds and still have stopping power with all that recoil. .45'sAre all I've ever shot so I don't know capacities and recoils on 9mm's, .40 or other popular calibers. What are the best self defense calibers. Also Glocks don't have a safety, I would prefer something with one. ANd what are the difference between the handguns with a hammer and one without, sorry I forgot the term for that, which is more commonly recommended. And one last thing what are say the top five make and models i the handguns suggested. Lots of questions i know but like i said i am new at this, sorry.
