Master Lock 90TRISPT Keyed-Alike Gun Locks, 3-Pack

They work. What more to say? (2010-07-11) Rating: 5/5
These are gun trigger locks, they fit both of my guns, they're a good value, and the mechanisms work just fine. The keyed-alike feature is also quite convenient. What more is there to say on such a simple product? If you need trigger locks, you won't be disappointed by these.
Replace one that's 20 years old! (2010-06-09) Rating: 5/5
I've had my Master Gun Trigger Lock for almost 20 years now, but I had lost 1 of the 2 keys for it and was getting nervous about losing the 2nd key when I came across this.

This is a great price for 3 locks - actually less than what I paid for 1 back then. And it comes with 6 keys that opens all 3 locks, so I'll be keeping 2 around and tuck 4 away in a safe.

It may not work well with all the guns, but they work great with the guns that I want to secure.

Comparing this to my old lock, it appears that it's been beefed up a bit, but the overall excellent design has stayed the same.
High hopes...let down. (2010-05-04) Rating: 1/5
After all the glowing reviews for this product, I bought 2 3-packs. They seemed well made and sturdy. These are supposed to be compatible with MOST firearms. Um...that isn't the case. I tried these on 6 completely different firearms. Rifles and pistols. All popular models. Only 1 of my firearms was able to be properly locked with this product (barely). Just trying to get these things to sit right was ridiculous. Save your money and pursue a different product.
doesn't work well with lever-action rifles. (2010-04-27) Rating: 2/5
Works great on firearms with a fixed trigger guard.

However, on my two lever-action rifles, it's not very effective -- probably no surprise, given the design. On an older Winchester 94, I can get position it to lock the trigger guard and trigger together, with some effort. On a Winchester 9422, it attaches itself to the trigger guard, and it just slides off of the trigger itself when the lever is used. The rifle can be loaded, cocked, and fired with the lock still in place.
Great gunlocks (2010-03-15) Rating: 4/5
Great gun locks. They work better on some guns then others. You sometimes need to mess around with them for a while to find the sweet spot. The key sometimes sticks in the key hole. The great thing is that with one key you can open all 3.
