Executive Carry V5 Slide For Glock 21 Gen 3 45 Acp Nitride

The Alpha Shooting Sports Executive Carry V5 slide for Glock 21 Gen 3 in 45 ACP is a precision-machined replacement slide built for shooters who want a carry-ready pistol with modern optics capability. This hardened stainless steel slide combines tactical functionality with refined aesthetics—CNC diamond checkering on the serrations gives you a solid, positive grip even in adverse conditions, while the custom machined top window port lets you mount a red dot sight directly to your G21. It's the kind of upgrade that transforms a reliable service pistol into a genuine modern carry gun.

Whether you're building a competition shooter, a duty-ready carry gun, or just want to modernize a trusted platform, this slide plays well with common optic footprints. The QPQ nitride finish handles the abuse of regular shooting and carry without fussing—you get durability without the fussy coating. Installation does require gunsmith work, so factor that into your build timeline and budget, but the precision of a professional fit-up pays dividends in reliability and longevity.

The Executive Carry V5 is fully compatible with Gen 3 G21, G20, or P80 PF45 frames and works with all standard 45 ACP Gen 3 G21 slide internals, so if you've got a parts kit on hand or you're sourcing components, you know exactly what will go together. This is a no-compromise approach to the .45 platform—engineered for shooters who demand function and finish.

Yes. The Executive Carry V5 is fully compatible with Gen 3 G21 frames and works with all standard .45 ACP Gen 3 G21 slide internals. If you're swapping slides on an existing build, your internals will drop right in.

Will this slide work with P80 frames?
