I haven't fired the 30 yet, but I want to own one to carry. The stock Glock triggers are tough to pull. On purpose. I upgrade mine for better action. On purpose.I tried a Glock 30 (45 acp) no joy! Couldn't get used to the trigger, I'm a die hard 1911 fan. Trigger pull short and sweet.
I also have a couple of WW2 rifles, but they are M1 Garands, one is the standard 30--06 and the other is a shortened version called a "Tanker Garand" it's in .308.
