Last year I was going to buy a glock and every time I start looking I end up getting a diff gun. I bought 2 -s&w and 2 sp 101 ruger . I want a glock 45 in a 5in barrel with fiber op site at 56 years old I just cannot see close anymore. Tarage shotting is what I want the glock for. I was going to get a 40 but was told the 45 has less kick then the 40 cal . I was also Told to get a 9 mil lot less money in bullets. I have lots of questions to be answers. Can any one help me with this, I do know glock is what I want with fiber opt sites and 5 in barrel. This time I'm getting the gun. Thank you Marty d.
