a degree in mechanical
engineering, and it doesn't
hurt to have a Voodoo Priest
standing by to assist."
I certainly concur. My
experience with the MK
I, and my current MK II,
goes back over 30 years
and I never truly mastered
the take down. In fact, the
last time my MK II was field
stripped was a decade ago.
That resulted in my arriving at my
local gunsmith with the proverbial 'paper
bag full of parts', a sheepish grin, and my
wallet in hand.
That won't happen with the new MK IV.

THE GUN
Introduced in mid-2016, the MK IV retains the
features of the MK III, but removes the sliding
safety button on the left side of the frame and
replaces it with ambidextrous thumb safeties,
while adding a redesigned bolt release lever.
The major change, however, is in the take
down procedure.
To field strip the MK IV, remove the
magazine and cycle to bolt to clear the
chamber and cock the gun. The hammer
must be cocked to disassemble. Put the
safety into the ON position. Grasp the barrel
in one hand and the grip on the other.
Depress the take down button below the
bolt, tilt the barrel downward, and lift the
upper unit off the frame. Slide the bolt out.
Everything is now accessible and the barrel
can now be cleaned from the chamber end
instead of the muzzle.
To reassemble; leave the hammer cocked
and the safety on, insert the bolt, slip the

upper unit barrel
notch onto the
forward frame pivot cut out,
tilt the upper unit back and
align the bolt stop pin with its
mating hole. Then press down
on the rear of the barrel until it
clicks into place.
I can't think of another .22LR
semi-auto pistol that is as easy to
field strip as the new MK IV. It's so
simple that even I got it right on the first try!
The new MK IV series is currently available
in three target models, two Hunter versions
and the 22/45 Lite. I choose the alloy-frame
target version (#40101, $529).
It features Ruger's adjustable target sights,
a 5.5-inch bull barrel with a 1:16 RH twist,
blued finish, checkered black plastic grip
panels, and weighs in at 35.6-ounces. The
trigger pull measured a bit over 5 pounds on
my Lyman gauge.
Accuracy testing is a part of any gun
test and it's been a few years since my
eyes would confidently allow me to wring
maximum accuracy from iron sights, so
Ruger's Picatinny Rail ($15) was ordered. I'm
also not a big fan of the skinny Ruger factory
grips. I assumed it would take a while for the
grip makers to catch up to the new gun, but
Ruger surprised me and already had a set
of oversized target grips ready for the MK IV
($70). They came along as well.
The rail and grips slipped on easily. I was
pleased to see that the rail sat low enough
on the top of the receiver to allow the iron
sights to be used when it was installed. That's
