Not worth the money and time. - Rival Arms RA42G001A Slide Completion Kit Compatible With Glock 9mm Luger G3/4

Got this kit for a new slide. Put it on and the trigger felt gritty and not smooth at all. Come to find out that the striker spring was the problem. Put the original Glock spring on the Rival Arms kit and the trigger was nice and smooth. Took the pistol to the range and shoots a few rounds and other rounds get stuck. I took it to the gunsmith and come to find out the extractor that came with the Rival Arms Kit is also not good. I had to pay the gunsmith $100 for that repair. Pretty much it costed me almost double for and the spring is still gritty and extractor does not work. Before I found out that the extractor does not work I called the company to warranty the Rival Arms and they were out of that kit since May 2021. I can't return it to opticsplanet been over 30 days. They don't even have an extra spring or extractor to send me. Its already November 6 month later and still out of stock.
