Dlc 43 glock barrel - S3F Solutions Glock 43 Drop In Match Grade Barrel, Threaded/Fluted

I got this yesterday and I'm very very disappointed with how the coating came off after just 25 rounds very disappointed! I called opticsplanet and they told I will have to call S3F to handle this issue.. which to be honest made me also unhappy you sale an item but when I call and tell you I have problems with it you push it on the maker! Well I call S3F and even email waiting on respond back. For 200 dollars I have to say not good! I have had other barrels and its normally happens around 400 to 500 rounds in not 25
