I used it on my gen 3 glock 21 but could be used on a glock 20 to convert to 45 acp (with ejector change). Used a holosun optic on it and has oem and wolf internals. Tfo suppressor height fiber optic Sights with tritium for night. Rear site was filed to allow room for red dot site. No damage to function of site (sites alone were over $100 plus internals and slide itself). Sorry I don't remember site manufacturer. Should work on gen 1-3 maybe 4 with a adapter not sure
