This is currently selling on Amazon for $100 I was curious whether it provided any better security than other trigger locks that retail for 5 to 10%.

The cost.

Now, we're going to put aside, for the moment the significant issue of fingerprint reader reliability when the finger is wet or dirty.

My testing did reveal deficiencies here, but other problems with this lock were so bad that reading the fingerprint actually became a secondary concern.

You see, the mechanical function tended to be unreliable, even when my fingerprint was correctly read and accepted by the electronics.

So let's install it on the Smith and Wesson MP 45 I will show you the problem.

I'm going to install it snugly over the trigger guard here, but not quite as tight as I would normally install a trigger lock.

You can see there's a fair bit of movement here.

Now I'm going to use this finger, which I've already registered with the reader.

Okay, that's red, Which means it was rejected.

Okay, now it's blue.

It's been accepted, but it is not coming off.

The only way to get it to come off is to squeeze the two halves of this together and then put my finger there and it will come apart now.

The reason I didn't install this more tightly in the beginning is if I had, it would have been very difficult to get off.

And that can be a devastating problem for someone who needs to access the firearm quickly.

So it all comes down to how tightly the trigger lock is installed.

Unfortunately, if I install any looser, there are two more significant problems.

The first is that you could reach in there and press the trigger, and the second is you could reach in with a thin piece of metal between the rubber and this medal and push that tiny black button.

I've actually done it reaching through with a lock pick, and once you push that button, you can add and delete fingerprints.

But as bad as all that is, my more base concern is that this product fails my litmus test for firearm locks.

And that is, can it be relied upon to stop a curious adolescent from firing the weapon.

Unfortunately, the answer is no, because this mechanical lock is extremely easy to open.

I'm going to install it back on the firearm and show you just how easy it is.

Okay, let's put some bottom of the key way.

Tension in there, and I'm not even really gonna try to pick this.

I'm just gonna put a pick in there, and we go it around a little bit.

And just that quickly, we got it open.

As a matter of fact, you really don't even need a tension tool.

End a pick.

I've been able to open it just by sticking a piece of metal in there and wiggling it around.

See if I can get it to work.

Yep, just that quickly.

Do that one more time.

Make sure it's locked.

Yep.

So it should be clear that this is not a product that you can rely upon either to provide access to authorized users or deny access to unauthorized users.

In any case, that's all I have for you today.
