Great choice for a second slide setup - ADE Advanced Optics Glock 26 9mm Pistol Slide

Rather than convert my only carry pistol, I bought this slide so I could leave the stock slide intact and have a dedicated optic-ready setup for competition and range days. My Glock 26 is Gen 3, and the fit was excellent once my gunsmith installed it. The RMR cut was square and true, and the optic we chose slid on without any fuss. During multiple range sessions, zero has held consistently and recoil tracking feels smooth and reliable — the gun doesn’t feel any different than it did before the swap. It’s a smart way to modernize an older pistol. Just remember: this slide was built for Gen 1–3 frames, and won’t fit Gen 4/5/6 without modifications.
