Fmk Firearms Ag1 Glock 19 Gen3 Frame Only - Blue Jay (Robin'S Egg Blue)

The FMK Firearms AG1 frame for Glock 19 Gen3 gives your carry or range build a fresh start with a complete, stripped polymer frame in an eye-catching Robin's Egg Blue finish. If you're assembling a Gen3 G19 from components or want to refresh an aging platform with a durable aftermarket foundation, this reinforced polymer frame delivers the same grip angle and ergonomics shooters know and trust, but with some notable improvements for real-world handling.

FMK engineered this frame with enhanced texturing across the sides, front strap, and back strap—giving you a secure grip in dry hands or when wearing gloves. The triggerguard is both undercut (for a high, aggressive grip) and oversized (for gloved shooting), and it works with any standard Glock 19 holster, so your existing gear stays in the fight. The reinforced polymer construction is designed to handle the rigors of training and carry without the weight penalty of steel.

This is a 100% complete, stripped frame—ready to accept your Gen3 G19 components (slide, barrel, internal parts, and small pieces). Note that the locking block is not included, so verify you have that part on hand before assembly. Whether you're building a budget-friendly duty gun, a customized range trainer, or a backup carry piece, this frame gives you a proven platform in a color that stands out in the safe.

Frequently Asked Questions

Will this frame work with my Glock 19 Gen3 slide and parts?

Yes. This is a complete, stripped Gen3 G19 frame compatible with standard Gen3 Glock 19 components. You'll need to source a slide, barrel, firing pin, springs, trigger housing, and other internal parts separately. The locking block is not included, so confirm you have that before assembly.

Does this frame fit in my existing Glock 19 holster?

Yes. The frame maintains the same grip angle and dimensions as the factory Gen3 G19, so it works with any standard Glock 19 holster.

Can I use this frame with gloves?

Absolutely. The oversized triggerguard is designed for gloved shooting, and the enhanced texturing across the front strap, back strap, and sides provides a secure grip even with gloves on.

What's included in the box?

The frame only. The locking block, slide, barrel, trigger housing, and all internal components must be sourced separately.
