Does not fit as advertised. - TRYBE Defense Sig Sauer P320 Compact Match Grade Non-Threaded Pistol Barrel

I bought this barrel along with one of Trybe defenses RMR cut sig compact slides. Both came in and I have nothing bad to say about the slide very well machined and good looking for a cheap entry level slide. The rmr cut was perfect and fit my Holosun 507c perfect. Unfortunately the same can NOT be said about there barrels. The barrels specs were completely out of line and would not seat properly to the point when I attempted to rack the slide the friction was so bad my slide was stuck and I had to dump gun oil all over it just to remove the slide. I also tried the barrel in my OEM sig slide to see if maybe the slide was the issue. Nope. Did the same thing in my oem slide. I don't understand stand how a company can make to products that are literally meant for each other and mess up that bad. I contacted Trybe Defense immediately and the customer service rep scoffed and kind of laughed and said that they get this quite often and that the barrel is simply out of spec and to return it for a different barrel. I return the barrel but obviously will be going with a more well known and reputable brand that stands behinds their products and doesn't just accept such a huge margin of error and acceptable quality control.
