Glock 43/43X/48 Direct Optic Cut & Slide Milling Service
Add a precision direct optic cut to your slimline Glock slide for a lower,
stronger, and more reliable red dot mounting solution. This service is designed
for Glock 43, Glock 43X, and Glock 48 slides using compact red dot optics such
as the Holosun EPS Carry, Holosun K-footprint optics, Vortex Defender CCW, and
Trijicon RMRcc.
Stonebridge Gunworks cuts slimline Glock slides for practical shooting, carry,
training, and performance-focused pistol setups. The goal is a secure optic fit,
proper mounting geometry, and a clean setup built for real use.
Best Use
- Glock 43, 43X, and 48 slimline slides
- Carry and training pistols
- Compact red dot setups
- Direct-mounted optics without a plate system
Supported Optic Cut Options
Available optic cut options include:
- Holosun K / EPS Carry / Vortex Defender CCW with factory rear dovetail retained
- Holosun K / EPS Carry / Vortex Defender CCW with rear dovetail deleted
- Trijicon RMRcc with rear dovetail deleted
For most EPS Carry and Holosun K-footprint setups, we recommend keeping the
factory rear dovetail when possible. This preserves more flexibility for backup
iron sight options and future resale value.
Recommended Slimline Glock Setup
For most Glock 43X and Glock 48 builds, we recommend the Holosun EPS Carry
paired with black backup iron sights and the factory rear dovetail retained
when possible. This creates a practical, durable setup for carry, training,
and everyday use.
If you need an optic with your slide cut, select one of the red dot add-on
options before checkout.
