Description The Alpha Dog’s “EG1 – Slide & Barrel Porting for Glocks” is the perfect addition to any Glock frame which aids in the shooters accuracy and control. Our EG1 porting combines our standard 10 and 2 o’clock porting position (4 ports) with a single 12 o’clock front port. The combination of these 5 ports provides the maximum amount muzzle down force with the least amount of velocity loss. It forces the muzzle downward, countering the typical muzzle rise and enables lightning fast target acquisition on follow up shots. Our EG1 Slide and Barrel Porting boasts an impressive 45-50% muzzle rise reduction with only a 3-5% velocity loss under 25 yards.

When a barrel vents under the slide (porting) not all the gasses will escape through the ports int he slide. This can cause heat to build up. Heat does not escape from flat surfaces efficiently. The heat will travel along flat surfaces until it reaches an edge to release from. Our EG1 Porting comes with slide milling and slide engraving which was specifically designed to increase the number of edges which heat can dissipate from and offer the user additional texture for slide racking and/or press checks. Sub compact Glocks tend to have very significant muzzle rise due to their small size and light weight. While the size and weight is great for a CCW, users find that they have a difficulty reacquiring the target after each shot. Our Slide & Barrel Porting for Glocks will eliminated the excessive muzzle rise and help you increase your accuracy and control. This and all of Alpha Dogs slide milling patterns are 100% CNC machined which increases milling accuracy and finish quality. NOTE: Do not use reloads, P or other types of over pressure ammunition with this porting. If used it could result in damage to your frame. NOTE: When a barrel is vented (ported) under a slide, more than normal carbon buildup will occur. It is highly recommended to disassembly and thoroughly clean barrel, guiderod assembly and frame after each use. NOTE: This is only available for Glock slides and is for milling service on a customer supplied slide ONLY. Unless selected as an option above, the milling cost does NOT include slide refinishing (Cerakote). Milled areas will remove the slides coating and expose raw steel which will rust if left untreated. ***This milling design does NOT look 100% identical on all Glock model slides. Slide pictured is a G43x. Milling patterns must be adjusted for model and generation.***
