Forward Controls Design, in collaboration with Revival Defense, has added two new members to the RF family: the 6315RF-A1-LH and 6310RF-A1-LH. Both models are built around the 1×16 LH suppressor standard, bringing A1-style geometry to left-hand threaded suppressor users while preserving the RF series’ compact, dual-role character that defines the line. The RF series has consistently offered practical devices that provide A2-level flash suppression with improved control and reduced ground signature. Earlier models such as the 6315RF and 6310RF feature a closed bottom, mimicking the A2 birdcage to minimize dust signature. The new A1-LH variants depart from that format, incorporating omni-directional porting. Their 360-degree layout provides slightly better flash performance, ensures even dispersion of gasses in all directions, and removes the need for timing during installation.

The A1-LH variants use a 1×16 LH suppressor mount compatible with silencers that feature the integral 1×16 LH mounting system. Examples include CAT QD silencers, the CGS SCI SIX, and the Cobalt Scrambler QD. They can also be adapted for HUB-style silencers using mounts such as the CAT TSFX and AI HUB QD. This approach provides direct compatibility with modern QD suppressor ecosystems without additional adapters.

Both the 6315RF-A1-LH (1/2×28) and 6310RF-A1-LH (5/8×24) are machined from 17-4 PH steel, finished in black nitride, and measure under 1.8 inches in length. Standard wrench flats simplify installation, and a blind hole is included for optional pinning to 16-inch overall builds. Like the rest of the RF line, these products are designed and manufactured in the United States of America.

Availability
The 6315RF-A1-LH and 6310RF-A1-LH are available now through Revival Defense, who partnered with Forward Controls Design on the RF series from its inception. Customers are encouraged to purchase through Revival Defense for immediate stock and shipping.

Bigfork, Montana manufacturer announces increased capacity Glock 19 and Glock 17 magazines with innovative over-insertion stop technology

BIGFORK, MT – October 7, 2025 – Shield Arms, a premier manufacturer of aftermarket Glock magazines and firearm accessories, today announced its DS-Series increased capacity magazines for Glock double stack 9mm pistols. The new product line includes the DS-18 magazine for Glock 19 and the DS-20 magazine for Glock 17, 34, 45, 47, and 19X models.

Increased Magazine Capacity: DS-18 and DS-20 Specifications

The Shield Arms DS-Series delivers what other aftermarket Glock magazines have never achieved: +3 round capacity increase in nearly the same footprint as factory magazines, combined with OEM-style reliability features.

DS-18 Glock 19 Magazine: 18-round capacity magazine for Glock 19 pistols, providing +3 rounds over OEM Glock factory capacity (standard 15 rounds) with only a minimal increase in overall magazine length.

DS-20 Glock 17 Magazine: 20-round capacity magazine compatible with Glock 17, Glock 34, Glock 45, Glock 47, and Glock 19X pistols, offering +3 rounds over factory Glock magazines (standard 17 rounds) with only a minimal increase in overall magazine length.

Additional magazines both smaller and larger coming in the DS-Series!

Innovative Over-Insertion Stop Technology

Both DS-Series Glock magazines feature an over-insertion stop precision-stamped directly into the steel magazine body—a critical reliability feature found in Glock factory magazines but missing in competitors aftermarket Glock magazines.

This feature ensures proper magazine seating depth, prevents over-insertion that can cause ejector damage, feeding malfunctions, and delivers factory-spec reliability. The result is an aftermarket Glock magazine that functions with the same mechanical precision as OEM magazines while providing +3 round capacity advantage.

“The DS-Series represents a breakthrough in aftermarket Glock magazine design,” said Brandon Zeider, CEO of Shield Arms. “We’ve achieved what the market has been asking for: significantly more capacity in nearly the same size as factory magazines, combined with the over-insertion stop feature that ensures OEM-level reliability. These magazines give Glock users the best of both worlds – extra rounds when it matters most, without sacrificing the profile or dependable function they expect from their pistols.”

Availability and Product Options

Shield Arms DS-Series magazines will be available soon through our Distributors and Retail Partners, internationally through our International Distributors, and on our website. Customers can purchase individual DS-18 and DS-20 magazines, or explore complete DS-Series combos and DS-Series magazine extensions for additional customization options.
