I had an Auto Ordnance conversion kit that I sold a couple of years ago. That is the only one that I know that came as a conversion kit for a 1911. I don't know if they still sell them.

If you want more power ........it is much easier to convert the 45 Acp to the mighty 45 super !

Do some research [ google ] on the 45 super .......... and I think you will find that round provides all the power you might want from the 1911 platform.

45 Super is great!

But no 10MM...I've looked, haven't found one.


460 Rowland is better! (if you reload)




Here is my 460 Rowland...I also have it converted to the 45 Super when I want to pack it and take off the extra inch or so.

45 Super factory ammo is bloody expensive, twice that of 10mm! 460 row is non-existent (I do not reload.)

Just for curiosity, how does 45 Super compare to 10mm?

I did find this, but it is very heavy exceeding 7 lbs. loaded and quite expensive: the Mech-Tech CCU (http://www.mechtechsys.com/1911.html)

According to their web site it appears that I could buy any 1911 10mm magazine and with their kit fire it? Does that sound right?

First off the way ammo prices are going, you SHOULD reload, even if you decide to go with 10mm most factory ammo you find is loaded way below what it is capable of.

Next off 45 Super is expensive, not if you reload. In addition a conversion for the 45 Super is about $20 or so done right.

1. Replace firing pin stop with EGW Flat Bottom Firing Pin Stop found at either www.midway.com or www.brownells.com can't remember.

2. Replace recoil spring with 22-24#

3. Replace firing pin spring with overpower one

4. replace firing pin with either titanium or a "bullet proof" one

Replace mag spring with heavy spring +5% ones from like wolffe

ok, so maybe it's not quite $20 but it's not much over it. Any steel framed 1911 can be converted. HK USP 45's do not need anything other than a stiffer spring change.

In addition there are more "fully supported" barrel's out there that are coming stock in some manufactures. Some of them are like the Springfield loaded models or TRP models.

460 is awesome, and you should see some of the numbers out of that mech tech thing!

here: http://www.concealco.com/ccu_460row.html
almost 2000fps and 1500+fpe with a 185gr! wow now THAT'S a 45!

Also, the kit you are referring to for the mech tech requires a 1911 lower, or glock.

as far as numbers go for factory ammo from buffalo bore:

10mm 200fmj 1200fps 639fpe
10mm 180jhp 1350fps 728fpe

45Super 185jhp 1300fps 694fpe
45Super 200jhp 1200fps 639fpe
45Super 230jhp 1100fps 618fpe

damn near the same. but, then again you can also shoot cheap 45Auto in a 45 Super :) and have the option of heavier bullets as well (230 gr) even light loaded down to 110Gr that are out there too.

10mm is good, but I like versatility. 45 Super for me!
