    It worked for me
  

*by J***E on Reviewed in the United States on December 3, 2020*

Had to return a swenson slide due to over machining of the rear sight, decided to give these guys a try. I don't base my purchases off everyone's reviews, I'd rather form my own opinion, so here it is. The fit and finish was good. Had a issue trying to get the gun to fire once assembled it was resolved by adjusting the trigger bar down a little bit. Other than that minor hiccup, I would say it's a pretty good slide. It cycles flawlessly, it does have some play in the slide, but for $200 range it's acceptable I'm my eyes.

    Bought A G21 Slide with RMR and Cutout-JUNK!
  

*by M***M on Reviewed in the United States on October 12, 2020*

This is my SECOND Glock 21 slide from RockslideUSA and NEITHER WORKED! I did not buy here but from Mfr site.The slide is NOT milled correctly! The standard Glock Firing Pin does NOT fit!!! It will not fire! Worthless! I had one, they sent me another, and it still does not work! The slide will not fire because it firing pin does not have the correct inner bore-they made it round. A Glock 21 Firing Pin is elongated, not round!Trigger will NOT work without Firing Pin being able to contact the primer.Have seen other problems with this, thought RockSlidesUSA had solved them, apparently not! Don't fall for theirs because it is cheap. They are selling cheap because they DO NOT work!Buyer Beware!!

    I got a G21 slide
  

*by N***O on Reviewed in the United States on August 13, 2022*

Would not completely into battery when firing unless there was only 1 round in the magazine. Slide cracked after about 200 rounds. The coating layer is too thick in places it shouldn't be and it is rough leading to energy loses.
