this is the lock-picking lawyer and what
i have for you today
is the master lock model 90 DSP t
trigger lock I'm demonstrating it on a
gun that's close to my heart it's one
that I received as a Christmas present
from my parents when I was 11 years old
it's the first gun in my collection a
Marlin little buckaroo a 22 caliber
single-shot bolt-action rifle so I'm
going to show you how we use this master
lock trigger guard on the very first gun
to ever enter my collection now this
master lock is a relatively standard
trigger lock design we have two halves
that separate when you turn the key and
pull them apart it's adjustable in
distance between the two halves and
that's done by using a ratcheting
mechanism you can see on this rotating
bolt down the center there's a number of
little grooves cut into it those grooves
will engage in this spring-loaded plate
right here and that creates a ratcheting
mechanism when you push the two halves
together this lock also contains a
number of features to help it from from
wobbling around when it's installed on
the lock we have these little yellow
spring-loaded buttons and we have
another number of little rubber nubs
that are molded into either side of this
lock again to keep it from wiggling
around once it's installed so let's put
it on this gun and see how it works
we take one half of it and we'll put it
on the the back side of the trigger
guard and take the other half make sure
the key is in the locked position and
insert the ratcheting insert the ratchet
mechanism until you have it down as far
as it will go and give it a good solid
squeeze okay
now we have this trigger lock installed
and before we get right to picking let's
talk about a number of shortcomings that
are common to all trigger locks the
largest one is the fact that you can
access
all of the controls on the gun other
than the trigger that means I can open
the action of this gun and load it up I
can access the safety and turn that
safety on or off all I can't do is
actually pull the trigger so that begs
the question does this actually
effectively block access to the trigger
you can see it's pretty tight on here
but if I really really pull on it I'm
able to open up a little bit of a gap in
between the stock and the lock and you
can see the trigger down there that may
mean that I'm able to reach in between
with a piece of metal like this see if I
can actually pull that trigger there we
go I just fired this law on this gun
with the trigger lock installed so you
really really really need to check the
fitment on any gun when you're using a
universal trigger lock to make sure it
actually does block access to the
trigger and keep the gun from firing
okay so let's say however we do have
this on a gun where the fitment is quite
good where you can't access the trigger
at all and there's no way to fire it
what does it take to pick this open
let's get a tension wrench in there
40,000 s pry bar it's gonna be a little
bit tricky picking this and not crowding
the camera view but we're gonna try to
do that using a 18,000 s pry bar I'm
sorry 18,000 standard hook from peterson
one is loose click at it to click out a
3
for is binding lifts you know pretty
high click out of four back to one
should be the last one and there we go
[Applause]
so for standard pins a relatively easy
lock to open certainly it would be made
a lot more difficult if we saw some some
security pins in here but it's a master
lock so for standard pins is what we get
now I will give credit where it's due
this master lock is better than a lot of
the competitors out there we look at
this one from Remington it's an all
plastic design it has a wafer core in it
so with master locks metal body and
standard pin tumbler core it looks
pretty good compared to that however we
can't just look at it comparatively we
have to look at this lock on its own
merits and with those four standard pins
it's not a terribly difficult lock to
open up so that's all I have for you on
this master lock model 90d SPT I hope I
gave you a few things to think about
probably the most important of which is
whenever you are using a universal
trigger lock like this you very very
verily very carefully check the fitment
and make sure it in fact blocks access
to the trigger that's far more important
important than the pick resistance or
anything else however as far as pick
resistance goes I think I showed you on
this master lock that it's pretty pretty
below average so that's all I have for
you again on this master lock 90 D SPT
