other day my friend Chili Ron and I were talking about guns
and grips and he mentioned that a few folks were installing
1911 grips on a Ruger® 22/45™.
A quick search on the Internet brought up the

Complete 22/45™ disassembly instructions
I have a 22/45™ in my collection, and I make my own 1911
grips out of Brazilian blood wood, I decided to make this
red grips would be a great contrast against the black frame.
steps for performing this modification are as follows:
disassemble the grip frame
the palm swells so the sides of the frame are perfectly
and tap 1911 bushing holes
1911 grip bushings.
Since the frame is plastic these may have to be
epoxied in place for extra strength.
the years I have made a number of improvements to my 22/45™:
a target hammer by Volquartsen
an over travel set screw in the trigger
a pre-travel set screw in the trigger
fiber optic front and rear sights by Williams Fire Sight
extended safety and bolt stop levers by Broken Gun Ranch
the Grip Frame
First I completely disassembled the grip frame following the
instructions on the Guntalk-Online web site.
This is literally a matter of pushing out pins and
having parts fall out. I
was careful not to lose any!
This was also a great time to clean all the nooks and
crannies that I couldn’t reach during normal cleaning.
Many of the pivot pins are held in place by a spring
that sits in a groove; thereby allowing the spring to perform
the Palm Swells
The instructions on the Internet say to use a high speed
rotary tool with a sanding drum, small grinding wheels, and
files to make the palm swells flat.
Since I have a milling machine at home I decided to
mill the palm swells.
couldn’t securely chuck the frame horizontally because of
the taper in the grip frame, so I chucked it vertically in the
machinist’s vise on my mill.
I used a four-inch long 1/4” square end bit at 700
RPM to “shave” off the palm swells.
This left a one-inch ridge at the top of the grip
used a high-speed rotary tool with a coarse sanding disk to
sand down the one-inch ridge.
I then used the tip of a cone grinding stone to finish
sanding down the ridge in the corners where it was recessed in
and Tap 1911 Grip Bushing Holes
I modified an old 1911 grip I had so it would fit onto the
frame on the appropriate side.
I marked the location of the grip bushing holes, then
drilled using a #3 drill bit.
I then tapped the holes using a 1911 bushing tap I
purchased from Brownells
1911 Grip Bushings
Long ago I purchased a 1911 Auto Bushing Driver bit from Brownells
This is the right tool for installing and removing 1911
grip bushings. Although
I was able to get the bushings snug onto the frame, I still
epoxied them in place so they would not come loose.
After I reassembled the gun I noticed that the sear pivot pin
protruded about 1/16” from each side of the frame.
I took a round-end rasp and my high-speed rotary tool
and cut an indentation in the grip to accommodate the pin.
Since the grips were already fitted to the frame prior to
installing the grip bushings, the grips fit perfectly.
I had to file a small cutout in the top left corner of
the left grip to accommodate the bolt lock lever.
the grip frame of the 22/45™ is wider than a 1911 grip frame,
once the 1911 grips were installed, the grip felt much
beefier. The gun
itself also felt heavier, which should help with accuracy.
though I used a mill to remove the palm swells, the
instructions on the Internet showed how to make this
modification using a rotary tool and files.
Now, with a few modifications, I can use 1911 grips on
my Ruger® 22/45™.
