  1. A.J. Kritzman

    Works as advertised. Can’t ask for more than that. Easy to install and just as form fitting as the Recover Tactical rail adopter for the Gen 2 Glock 17. So, breath new life into your Gen 2 Glock 21 by giving it the ability to accessorize like its younger brethren. Don’t be left in the dark!

    (Original) Kann man nur empfehlen, absolut passgenau sieht gut aus und das wichtigste es hält.

    (Translated) I can only recommend this product, absolutely perfect fit, looks good, and most importantly, it does what it’s supposed to do.
