Description
The SCT Manufacturing SCT 43X SC frame gives fans of the slim single-stack Glock platform a fresh foundation to build on. It's a stripped polymer frame cut for Glock 43X and 48 slides and internals, finished in a clean Flat Dark Earth that pairs nicely with just about any slide color you throw at it. Where the factory 43X grip can feel a little plain, this one leans into aggressive texturing that locks into your palm without shredding your hand, and it keeps the same grip angle you already know so your muscle memory carries right over.
What Sets the SCT 43X SC Frame Apart
The details are where this frame earns its keep. You get a thumb accelerator pad and a recessed mag release area for quicker reloads, an ambidextrous magazine release, and a flared magwell to help guide those slim mags home. Up front there's a modified factory Picatinny rail with an extra mounting slot for your light or laser, plus a larger trigger guard that plays well with gloves. The extended beavertail with a low-profile bore axis helps you sit high on the gun and keep muzzle rise in check, and there are serrations on top of the beavertail to cut glare along with an index point on the trigger guard.
Building on the SCT 43X SC Polymer Frame
Since this is a stripped frame, it ships bare with a locking block included and is meant to accept your existing 43X or 48 internals. Folks who've made the swap tend to find it a straightforward transfer of factory parts, and there's plenty of video walkthroughs out there if it's your first build. If you're not comfortable with fitting fire control parts yourself, it's worth having a gunsmith handle assembly to make sure everything functions safely.
Built from SCT's proprietary polymer blend and multi-caliber ready for compact 9mm components, this frame is a smart pick for anyone wanting better grip and control out of their slimline Glock without starting from scratch.

Frequently Asked Questions
Will my Glock 43X or 48 internals fit this SCT 43X SC frame?
Yes, the frame is designed to accept standard Glock 43X and 48 fire control components. Since it ships stripped with a locking block included, you'll transfer your existing internals over during the build. Many builders find the parts swap straightforward, though a gunsmith can handle it if you'd rather not fit trigger parts yourself.
Does the SCT 43X frame come with any internal parts installed?
No, this is a stripped frame, meaning it comes bare except for the included locking block. You'll need your own Glock-compatible internals to complete the build. It's aimed at folks upgrading an existing 43X or 48 or assembling a fresh slimline setup.
Is the grip angle the same as a factory Glock?
It is. SCT kept the same grip angle as Glock so your point of aim and muscle memory carry right over. The main differences you'll feel are the more aggressive texturing, the thumb accelerator pad, and the extended beavertail that lets you ride higher on the gun.
Can I mount a light or laser on this frame?
Yes, the SCT 43X SC frame includes a modified factory Picatinny rail with an additional mounting slot up front. That gives you room to run a compact weapon light or laser sized for the slimline platform. Fitment will depend on your specific accessory, so check its footprint before ordering.
