Description
The Selector Switch for Glock in Green is a straightforward upgrade for shooters who want a dedicated dry-fire training tool or a unique range toy. It replaces your backplate with a functional, three-position selector that gives you the manual of arms of a select-fire weapon without the NFA paperwork or price tag. I’ve installed dozens of these in my shop, and they’re a solid piece of kit for a very specific purpose.
Key Features
- Three-Position Function: Offers SAFE, SEMI, and a simulated AUTO setting. The auto position provides a resetting trigger for rapid dry-fire practice.
- 6061 Aluminum Construction: It’s machined well and anodized a bright, consistent green. It’s durable for its intended use, not just a plastic toy.
- Direct Backplate Replacement: Installation is simple—drift out your rear slide pin, swap the backplate, and reassemble. No gunsmithing required.
- Glock Gen 3-5 Compatibility: Fits the vast majority of common 9mm/.40/.357 SIG models. I’ve run this on a Gen 5 19 and a Gen 3 17 without issue.

Honest Assessment
Pros: This switch excels at its primary job: dry-fire repetition. The auto setting lets you work on trigger reset and sight alignment faster than pulling and releasing manually. The build quality is good for what it is, and the green anodizing is eye-catching. After decades of testing training aids, this one actually adds a useful dimension to dry practice.
Cons: This is not a binary trigger. It does not make your Glock fire faster with live ammunition—the “auto” function only works during dry-fire. At over $120, it’s a niche product. You’re paying for a novel training tool, not a functional performance upgrade. The selector can feel a bit stiff initially.
Who Should Buy This
Buy this if you’re a serious shooter who does high-volume dry-fire training and wants to simulate automatic fire drills. It’s also a fun, conspicuous addition for a dedicated range gun where you want a unique look. I would not recommend this for a defensive carry pistol, as the selector is a snag point and serves no tactical purpose for that role.
Frequently Asked Questions
Will this make my Glock fully automatic?
No. This is a training aid only. The selector switch mechanically blocks the firing pin when in “safe” and provides a resetting trigger feel in “auto” for dry-fire. It does not alter the firearm’s internal fire control group to increase rate of fire with live rounds.
Is it difficult to install?
Not at all. If you can field-strip your Glock to remove the slide, you can install this. It requires no permanent modification and uses the existing rear slide pin. The whole swap takes about 60 seconds.
Will it fit my Glock 43X/48?
No. This selector is designed for full-size, compact, and subcompact double-stack models (like the 17, 19, 26, etc.). It will not fit single-stack Slimline or G42/G43 models.
