A friend gave me a Wilson Combat .22LR conversion for 1911. (Actually made by M&P)
He said it couldn't hit the side of a barn @ 10 feet. When I looked at it. It appeared the barrel bushing was missing.
So I go online to look for one. Turns out they don't come with one nor do they make them.
What kind of hookey s&*t is this? .030 of play on each side????? WTF? The barrel can move freely from top to bottom a total of .060"
& .060" side to side, or a combination of both on each shot


(Wilson Combat actually advertises this as the most accurate conversion on the market...Laugh2

So I made my own barrel bushing and friction fit it in about 1/4". just enough so I could still get the barrel out for disassembly.
Now it hits 9's and 10's at 40 feet. And I think it improves the look as well.


At first the bushing to barrel play was .0015" but has since opened up to .004.
I knew this would probably happen as the machining lines on the barrel wore off. So I'll be making a new bushing when they are finally gone.
Which sucks as the slide/barrel opening isn't round. The sides are longer. This bushing takes some extra effort.

I was invited to join a local bullseye league. For 25yrds.
The sights on this conversion are adjustable. But man they suck !!!
Time to make some more alterations.

First up. V grove the front sight. So I can see the impact area of the center line with the top of the sight. Kind of where the lines meet on a letter T.


Now a contrasting color. (yellow) Followed by using the micrometer to scribe the center of the front sight top to bottom.


Then for the rear sight.
Measure for center. flatten the center area for paint with a file.
Paint the center. and along the top edge. A little white to contrast against the sides of the front sight. Let it dry then covered it with nail polish. Once dry again. I covered it in black paint and waited for it to be tacky.
(probably should have gotten to it sooner. Now I'll have to redo the center line) and once again used the micrometer to scribe center top to bottom through the black to the contrasting color underneath.

(ok this picture really sucks. I thought I took a better one later. The line is now straight and the white on the sides isn't bleeding into the nail polish anymore)

I adjusted the sights so the shot goes right in the top of the V-groove.
Now I'm hitting 8's, 9's & 10's at 60 feet.
Only thing left is a lighter spring so I can run the match ammo instead of the HP rds.
Oh. And to do a trigger job on my Sig 1911.

What do you think of my project so far?
I'm kinda surprised how accurate it's getting.

Very cool. What does the bushing look like out of the gun? Normal 1911 bushing?

It's a press fit bushing.
Out of the slide it almost looks like a ring for a finger, only wider. I had to cut the outside diameter to the largest size. Bore the inside diameter.
Then mount the bushing from the I.D. and off center it in my 4 jaw chuck to trim each side to the proper width. gently tap into the slide while checking to ensure the barrel could still be removed.
Once the barrel only had .020 clearance to be removed. I didn't tap it in any further. I debated on trimming off the excess bushing protruding from the slide. But chose to keep it for ease of bushing removal in the future. Which I'm not looking forward to as it's in there pretty good.
I should have taken the time to clean up the oem barrel O.D. and re-blue it. Then I wouldn't have any wear in issues.
 
Decided it needed a new look.
Before





After: (but not finished)


I still have a few spots to remove on the front. And I have to find a sight removal tool to finish the rear site area.


OH. If you happen to know of anyone that has lost the little set screw for the rear sight on a Sig 1911 Super Target (perhaps other sig target sights as well)
It takes a 3mm thread x 8mm long Allan cup screw
