I'm looking for some opinions before I get the chance to go to my local gun shop. I want to buy a glock in 45 acp and am trying to decide between the 21 and the 30. I have the glock 23 and it's awesome, but they don't have a 45 that's the same size. The 21 is bigger and the 30 is smaller. What are some of your opinions. I just joined and this is my first post. Thanks for any help/ advice Wanna kill these ads? We can help!
