Aftermarket 1911 Barrels

[KeystoneWeaponBK]

Hey there,

I hope I'm putting this post in the right place but I wanted to see what your thoughts were on some of the aftermarket "match grade" barrels out there. I did some searching from my mobile app on the site and didn't find what I was looking for so I hope I'm not asking an already beat-to-death question but I want to build or have built another 9MM variant possibly and was wondering if y'all had any guidance from your collective experience. I've heard decent chatter about Kart barrels and wanted to see if anyone could chime in, thanks!
