I'm new to the site.............this is my first post. I'm always trying to wring the most accuracy out of any firearm I own. I carry a Glock 27...........not the most accurate Glock, by any means. I've done all the trigger mods, sight mods, etc. that I can do without breaking the bank. The only thing I've not done is to replace the barrel. Would a KKM barrel be worth the money, being such a short barrel, or are they pretty much considered competition barrels only?
