I have a G-17 (9mm) and G-37 (.45 Auto)
Of the two I like the 9mm better. Just seems to handle better. Maybe I just have more target time with it.
When it comes to Guitars, once you find one that fits you, you just want to stay with it. It makes you a better player.
I’m getting the feeling the same is true with guns. I’ve tossed and turned between a .45 and nine MM. I’m thinking it’s time to pull the trigger on the 17.
