I have only one Glock threaded barrel and it was made by Lone Wolf. I had a hard time finding one that wasn't outrageous as I have a G37. When NDZ performance carried TBs I was able to get one for $117.95.
I have LWD's for most of the 9mms and a SL in a G21. The storm lake looks a little nicer, but not worth the extra hundred bucks in my opinion. The SL was all I could find in stock when I needed a threaded G21 barrel. I literally had an Octane 45 for a couple months and nothing to attach it to.
And as far as the LWD barrels go- forget about polishing off the logo if you don't want to pay more for the blind marked barrel. Those things are burned in with what appears to be a sinker EDM. That logo is deep in the steel.
