Bad quality control - Lone Wolf Arms Glock Slide Completion Kit

Bought for a 10mm build. The extractor didn't work, even after filing the forward stop, it did not apply enough pressure to reliably extract the case from the chamber. The safety plunger was also not correct and was likely meant for a 9mm model, because it was .235" instead of .265" like the Glock 20/21 plunger. Because of this, I had to buy a Glock safety plunger and extractor. Wish I had bought the Glock kit from the start.
