I wanted a compact SBR to mimic a sub gun. Also I have a suppressor in purgatory for it. To keep it as compact as possible I went as short as reasonably possible. So if building with the same intentions, I’d do it again.
I don’t have any complaints. It’s just a range toy to be honest. Not that I wouldn’t use it with some +P HSTs for defensive use. Would be the same as using a Glock 17 but even easily being shoulder fired.
Mine is a Glock lower. Since I already had so many Glock magazines it just made sense.
