Suppose I have a 1911 that came from the factory with a bull barrel.
How hard is it to convert it to use a standard barrel with a bushing?

Google for '"bull barrel" 1911' and see. I asked Rock Island Armory
if I could get the 10mm one with a standard barrel and they said no.
They don't do custom jobs.

Does anyone here have that particular pistol? Is its slide cut so that
a barrel bushing can be installed?

There's various sorts of bushingless 1911s out there, all having barrels as
large or larger than the O.D. of the regular bushing. You mostly see that
on the cut-down and compact .45s since there's no real space to use a regu
lar bushing. Most have a large muzzle and taper back to the locking lugs,
don't know if I'd call that a "bull barrel" or not. Don't see the advantag
e for a full-size gun, would limit what you can do for barrel swapping.

There's no standard here like with a regular 1911, eveyone has their own id
ea. I very much doubt that the slide is a regular 1911 slide with a bushin
g cut and it just has the bushingless setup installed. First one of these
I ever saw was back in the '80s at an NRA convention, Detonics had a target
gun with that setup, supposedly the interior of the slide was contoured li
ke a V-block to position the barrel exactly the same way for every shot. H
aven't seen one since, so apparently not a hot seller. The point being tha
t once departure is made from regular 1911 specs, anything could be done in
side or out.

If the O.P. wanted a 10mm barrel and slide with a regular bushing setup on
that particular gun, he's probably going to have to buy the parts and fit t
hem. If the frame is cut for a ramped barrel, that could present problems
obtaining barrels, 10mm isn't that popular and finding a supplier with part
icular custom features might be a challenge. Want it your way, you may hav
e to build it or have it built. At best, a new top end is probably going t
o be north of $500 on top of the cost of the gun. If you can't fit the par
ts yourself, there will be gunsmithing costs added to that. I'd estimate t
hat milling that bushing cut would probably cost more than half the cost of
a new slide, if the I.D. and other internal contours work out, and you've
just cut the resale value of the gun.

I looked at the economics of converting one of my .45s to 10mm, at the time
, it cost twice what I could pick up a factory refurb Glock 20 for, so that
's what I did. Mid '90s, one could be had for $225. A no-brainer. I want
ed to shoot 10mm, didn't necessarily have to be IN a 1911.

They might be able to help you.

After asking Kimber about it, they pointed me to the Custom TLE II,
which can be had in 10mm and has a bushing-type barrel. The price is a
bit on the high side for what I'm planning to spend (probably because of
the tritium sights), but it's not out of the ballpark. Friends have
told me that Kimber is a better choice anyhow because of a
fully-supported chamber.

I have considered a Glock 20 for satisfying my 10mm cravings. I might
get one, but Glocks have a blocky feeling that I find slightly
unpleasant.

So, if I just drop in a semi-fit 10mm barrel and change the recoil
spring, I should be good?

David,

All of the barrels I got from them were for Sigs. They all dropped in
just fine.

I have no idea about your 1911, but I am certain that they could tell
you everything you need to know.

Kind Regards,

Tom

"semi-fit 10mm barrel" barrel bushing/raceway cut????

In My opinion, it really isn't worth doing (Gun tech/Smiting, Range
"test" trips, time spent, etc...), and maybe get the right gun with the
barrel you want instead, unless you like tinkering a lot, like used to, then
got tired like this!
