Stonebridge Gunworks Porting Service • GLOCK2627Service
Glock 26 / Glock 27 / Glock 28 Porting Service
Add clean, factory-style slide and barrel porting to an eligible Glock 26, Glock 27 or Glock 28.
This Stonebridge Gunworks service is for customers who want a compact Glock porting setup
while keeping their existing Glock slide assembly.
This listing is available for any generation Glock 26, Glock 27 and Glock 28 when using
the customer-provided factory slide and factory barrel. Send only the slide and factory barrel
for service unless Stonebridge Gunworks specifically instructs otherwise.
These ports are intentionally smaller than the original factory C ports found on the Glock 19C and 17C. The port size and placement are designed specifically for the shorter barrel and slide length of the Glock 26, Glock 27 and Glock 28, and tuned for these specific models. The same port geometry is used on the Glock 28.
