Solid, simple trigger lock—affordable keyed-alike pack that boosts basic firearm safety.
You’re putting a rifle or pistol away and want a fast, no-fuss way to block the trigger. Maybe you have kids in the house or you store guns in a vehicle. A compact, keyed trigger lock gives peace of mind when a full safe isn’t practical. I’ve used small trigger locks for years when traveling, hunting, and for temporary storage. They aren’t a substitute for a safe, but they stop accidental trigger access and slow a casual thief. Below I test and break down one of the most common keyed trigger locks on the market so you can decide if it fits your needs.
Is Master Lock 90TRISPT Gun Trigger Lock with Key Good?
This trigger lock is a yes for basic, practical firearm safety for most gun owners. In my experience, the Master Lock 90TRISPT gun trigger lock with key does what it promises: it blocks the trigger, is easy to install, and the keyed-alike pack means one key fits all three locks. It’s not engineered to stop a determined thief with tools, but it’s perfect for preventing kids or guests from accessing a firearm quickly. I used these on a hunting rifle during travel and on a bedside pistol for short-term storage. In both cases, setup was quick and the locks stayed snug and secure during handling. If you want a simple, low-cost solution that reduces risk and adds a layer of safety, this lock fits the bill.
My First Impression for Master Lock 90TRISPT Gun Trigger Lock with Key
The pack arrived in simple retail blister packaging. Each lock sat in its own molded slot with two keys included per lock. Out of the box the finish looked clean. The body is cast metal with a zinc feel and a small amount of plastic trim around the locking pin. The shackle and locking post are solid for a small device. I clipped one onto my carry pistol’s trigger guard in under a minute. The keys turn smoothly and the mechanism does not feel flimsy. My first reaction was relief — it felt like a usable safety tool rather than a throwaway gadget. I was slightly surprised by how compact it is. Overall, it met my expectations for a budget-friendly trigger lock.
What Makes It Stand Out / Key Features
- Keyed-alike pack of 3 — one key opens all locks in the set
- Durable metal housing with weather-resistant finish
- Low-profile design fits most trigger guards and many polymer frames
- Includes spare keys (two per lock) for convenience
- Simple, single-action locking and unlocking with clear key insertion
- Lightweight and portable for travel or short-term storage
What I Like
- Very easy to install and remove — takes seconds
- Keyed-alike convenience — I lost one key and still had a spare that opened all three
- Compact size that doesn’t interfere with storage cases or racks
- Solid build for day-to-day use and travel
- Good value — three locks for the price of a single higher-end lock
What Could Be Better
- Not resistant to cutting tools — not theft-proof
- May not fit very large or oddly shaped trigger guards on some rifles
- Keys are small and could be lost if not stored carefully
My Recommendation
If you need a quick, reliable way to block the trigger and add a layer of safety, the Master Lock 90TRISPT gun trigger lock with key is a practical pick. I recommend it for hunters, casual shooters, and gun owners who travel with firearms and want a compact lock that won’t break the bank. It’s also a good choice for families who want a secondary measure in addition to other safe storage methods. The keyed-alike three-pack is handy when you want one key to manage multiple guns.
| Best for | Why |
|---|---|
| Travel hunters | Compact and fast to install before transport |
| Families with kids | Simple extra barrier for accidental access |
| Budget-conscious owners | Three keyed-alike locks offer value and convenience |
Alternative Products You Can Consider
HKS 3000SP Trigger Lock — This is a heavier-duty trigger lock with a thicker locking bar. It works well for owners who want a stronger physical deterrent while retaining a simple keyed design. It’s bulkier than the Master Lock 90TRISPT, but offers slightly more resistance to physical attack. Best for users who prioritize a firmer lock and are willing to accept more weight.
Browning TriggerSafe Trigger Lock — Browning’s lock offers a low-profile fit and often includes molded pads to protect finishes. If you care about avoiding scratches on high-end finishes or polymer frames, this is a polished option. It’s similar in ease of use to the reviewed lock but positions itself on fit and finish.
Kidde Cable Gun Lock — A cable lock isn’t a trigger lock, but it’s a law-compliant and affordable option for rifles and shotguns. It won’t be as compact for pistols but creates a reliable chamber-blocking solution. Consider this if you need a universal lock for multiple firearm types.
| Product | Best For | Key Difference |
|---|---|---|
| Master Lock 90TRISPT Gun Trigger Lock with Key | Simple, budget trigger security | Keyed-alike 3-pack; compact and portable |

Final Verdict: Which Should You Buy?
If you need a compact, affordable lock to add a layer of safety, the Master Lock 90TRISPT gun trigger lock with key is my top pick. It’s easy to use, portable, and the keyed-alike set is convenient for multiple guns. Choose the HKS 3000SP if you want a more robust physical deterrent. Pick the Browning lock if finish protection and fit are your priorities. For universal, low-cost chamber blocking across rifles and shotguns, go with a cable lock like Kidde. In short: for everyday, low-cost safety and travel convenience, the Master Lock option is the best balance of value and function.
FAQs Of Master Lock 90TRISPT Gun Trigger Lock with Key Review
Will this trigger lock fit my pistol?
Yes for most standard pistols. The lock fits many trigger guards and polymer frames. Very large or irregular trigger guards on some rifles may not fit. Check the product dimensions if you have an unusual firearm.
Can the lock be picked or cut easily?
It is not pick-proof or cut-proof. The lock deters casual access and stops unintentional use. For theft resistance, use a secure safe or higher-security lock.
Are replacement keys available?
Replacement keys can be requested through Master Lock customer support or by ordering a new lock pack. Keep spare keys stored safely.
Is the keyed-alike feature secure?
Keyed-alike makes management easy but means one key fits all locks in your set. If you need unique keys per gun, look for individually keyed models.
Can I use this lock for long-term storage?
You can, but it’s best as an extra barrier. For long-term secure storage, a gun safe or locked cabinet is recommended.
