10MM Commander...

Colt Super

1) Is the frame of the 10MM the same as a standard 1911 ??

2) If one had a lightweight Commander, and put a 10MM top end on it, would firing it destroy the frame ??

3) Would the 10MM mags fit the standard frame ??

Thank you.

Doug IMHO the 10MM was more then a 1911 type frame was capable of standing up to high usage of this high power cartridge. I believe that is why the delta was dropped from the product line. Now take an aluminum frame and I think you have recipe for a very short life span Plus a handful when it comes to recoil . Remember recoil goes up as the weight of the fire-arm goes down. The grip design of a 1911 does not Roll in your hand like a SAA and most big bore double action revolvers Weigh a lot. I had single shot bolt action conversion in 308 Winchester that fit on a 1911 frame and recoil was [:0][:(][V] brutal

1 yes,different ejector. 2 with a stong enough recoil spring, it should work. You would have an open space due to the shorter dust cover on a Commander frame. 3- Mag lenght is the same. A Wilson 45 mag will work with 10mm ammo. I built a 10 on a full size Essex frame. Really need a 10 mm slide stop which is a no.4 to work properly.

Doug;
I've done a .400 Corbon on a 1911 frame for my son. I prefer Commander size, but haven't tried the .400 Corbon on it yet. As Perry said I would feel a light weight frame may suffer.
.400 Corbon is a nice load

So could I go back to the Delta question, can the Delta stand up to the 10MM or not?

Hello 5MM it all depends on what you term "STAND UP TO 10MM" means to you I have one series 70 that has more then 300,000 rounds of MILD target loads through it 820 FPS 200 grain lead and it has had no frame or slide damage but the recoil spring is Matched to the load. The 10MM will need a very heavy recoil spring and I have not done any long term testing but would think 5000 rounds would be a good point to retire it as a CC pistol . I think the 10MM is borderline for the design and size of components. Your Mileage May Vary.

...Doug, my OEM DE mag fits into my Govt. A1 frame...and the rest too, and drops free.

...I agree an Alum frame w/10mm could take a beating if using the hotter 10mm rounds but, most OTS rounds shouldn't wear on it as they fall within .45acp pressures/fps OR BELOW, all bets off if using some hot Double Tap 10mm rounds though

...???...not sure what your asking? IF your asking if the ORIGINAL/pre-enhanced Colt DE, made in 87 (first run) & part of 88, will stand up to 10mm rounds, of course...just not a steady diet of HOT 10mm.

The FBI got the ball rolling for 10's, but the recoil, with the then ALL hot rounds was too much for the female agents to handle so...what does the FBI do? The dummies ask to have the hot 10mm round loaded DOWN to LESS than the pressures/fps of the .45acp, DUH!
THEN, the brainiacs decided why spend/change to the 10mm if it was not even an improvement over the 45!!! GO FIGURE!

...Pre-Enhanced, as mentioned above are the DE's that did not have an itty bitty extra cut in the slide, and with a LOT of HOT rounds the slides could, and some did, develop a crack in the slide...this was remedied with a small cut that Colt started making in the slide after the problem was identified, problem corrected for rest of a great run that ended in 98.

...I have a pre-ehanced DE...have shot a LOT of HOT loads thru it w/o a problem. Consider that a HOT round 10mm can reach the ballistcs of a .357mag, not the .357sig. I don't use the pocket draining worthless buffers either. No, I don't feed it a steady diet of hot rounds, but it's my favorite Colt and I own a couple...[;)]

There is a company that currently manufactures commander profile 1911 type 10mm handguns... Dan Wesson... Just if your interested in something like that.

You can puckup frames from caspian arms if you wanna build your own. They offer carbon steel, stainless, aluminum, and titanium. They been around at least ten years or more that I know of, and if your frame broke, it wouldn't be hard to replace...

tomh.

Looks like the Colt Delta may be back for 2009!

I have two Deltas. One is stainless and the other is bright stainless. They are both very reliable and as strong as can be. Rule number one is to leave the double springs in. Some guys took one of the springs out when the pistols first came out. The main fodder of the day were the hot Hornaday loads. I think you can all see how that will play out. That is how the rumor got started. Thank God the Glock owners did not shoot those rounds through their pistols or there would be a lot of Glock owners named "Lefty" now. The 10mm loads you get today are not near as hot as those were. But to answer your question, I would not shoot 10mm in an aluminum frame. I am sure it would work, but the stress would prematurely end your endeavor. Stick with a steel frame and live with the weight.
