Why This One?
When a new product hits our shelves, the first thing I do is pull it from the box and inspect it like I would for my own kit. With the Trinity II, that initial inspection was telling. The construction feels solid, with a durable, well-machined presence that matches the manufacturer’s claims. Having personally handled the batch we received, I can confirm the finish quality is excellent. Our staff noted a distinct lack of visible tooling marks, which speaks to a higher level of manufacturing care. This isn’t just a spec sheet review; it’s based on the unit sitting on our bench. In a market where consistency can be an issue, the Trinity II has proven to be a reliable performer for our customers, who report a 4.7 out of 5 satisfaction rating. For someone who spends weekends on the range or prepping gear for competition, that kind of track record matters.

Honest Assessment
Based on our handling and what our buyers tell us, here’s the straightforward breakdown.
✅ Superior Fit & Finish: This is the pro where our inspection matters most. The units we’ve handled show precise machining and a consistent, high-quality anodized finish. It looks and feels like a professional-grade component.
✅ Proven Reliability: The low return rate we’ve seen since stocking it in early 2024 is a solid, real-world indicator. Customers aren’t sending these back with problems.
✅ Thoughtful Design: The tool-less installation is well-executed. It simplifies the process while maintaining a secure fit, something I appreciate from a gunsmith’s perspective.
✅ Balanced Weight: At 7.9 oz measured on our scale, it adds minimal bulk. It maintains the firearm’s handling characteristics without making it front-heavy.
✅ Discreet Packaging: Arrives in a protective clamshell with no external markings, which is a considerate touch for shipping and storage.
❌ Price Premium: At just under a thousand dollars, it’s a significant investment. It’s not an entry-level part.
❌ Compatibility Specificity: You must double-check your exact Glock model and generation. It’s not universally “one-size-fits-all” across every variant.
❌ Learning Curve: While installation is tool-less, first-time users should thoroughly understand their firearm’s field-stripping process. Rushing can lead to mistakes.
Who Should / Shouldn’t Buy
Consider the Trinity II if: You prioritize build quality and consistent performance over lowest cost. You’ve handled budget options before and been disappointed by fit or finish. You value a design that’s been vetted by actual users (like our 4.7/5 rating suggests). You’re comfortable with the investment for a durable, well-made component.
You might skip the Trinity II if: Your budget is firmly under the $800 mark. You’re looking for your very first component of this type and want the absolute cheapest option to learn on (and potentially replace later). Your specific Glock model falls outside its stated compatibility range.
Q & A
Is the finish as good as advertised?
In our experience, yes. The batch we received and inspected had an excellent Type III hardcoat anodized finish with no visible tooling marks. The construction feels durable and precisely machined, matching the manufacturer’s claims.
How difficult is installation?
It’s designed for tool-less installation but requires you to field strip your Glock. If you’re familiar with that process, it’s straightforward. If you’re not, take your time and reference your firearm’s manual or a reliable guide first.
What’s the real-world weight?
We measured it at 7.9 ounces on our calibrated bench scale. This adds minimal weight to your setup, preserving the firearm’s balance.
Is it reliable?
Based on our sales data since early 2024, the Trinity II has a very low return rate. Customer issues have been minimal, which in our retail experience is a strong indicator of a product that works as intended out of the box.
Where can I buy Trinity online?
You can purchase the Trinity II right here at Glockautoswitches. We’re an Atlanta, GA-based retailer, we handle every product directly, and we ship quickly and discreetly.
What generation Glocks does it work with?
It’s advertised as compatible with Glock Gen 1 through 5 models. However, you should always verify compatibility with your specific model (e.g., G17, G19) as there can be subtle variations.
What’s included in the box?
The Trinity II unit itself comes secured in a protective plastic clamshell case. No additional tools or parts are typically required or included for installation.

Was worried about fit but it dropped right in on my G19 Gen5. Works perfectly after a few hundred rounds. Very pleased.
Brittany S. (verified owner) –
Bought this as part of a larger build project. glockautoswitches.com had the best price by a decent margin and shipping was fast. The Trinity II itself is well-made — Solid machining on this one. Overall this is exactly what I needed. Already ordered two more accessories from this store for the same build.
