Need a 10mm 1911

I've been kicking myself for selling my old Colt Delta, and never got around to replacing it before the hammer dropped.

Digging through the safe the other day I came across a bare Dlask frame I bought years ago....

I know I need a few things, barrel, ejector, spring(s), mags.

I have enough 1911 small parts to rival a rebuild armory, but they are mostly for run of the mill .45 pistols.

Is there anything else specific to the 10mm I need to complete this pistol? Will a .45 slide work?

The big reason for this project is I have enough 10mm ammo to swim in it like Scrooge McDuck, would be nice if I had something to use it in.
 
Colt and Kimber are two renowned brands that offer high-quality 10mm 1911s. Colt's Delta Elite is a classic choice, known for its reliability and solid construction. Kimber, on the other hand, has several models like the Kimber Custom II, which are praised for their accuracy and ergonomics.
Another option to consider is the Dan Wesson Bruin, which is specifically designed for hunting and long-range target shooting. Its longer barrel length provides superior accuracy, which is a significant advantage for precision shooting.
 
The breech face on the 10mm slide is smaller than the 45 slide. You might also get feeding and extraction issues as the smaller diameter case moves around in the extractor. You might be able to find a 40 SW slide that would work. I asked Dlask about building a 10mm about 4or 5 years ago but they weren't crazy on the idea.

Good luck with the project wish I could be more help.
 
10mm/40sw slide/ejector with 10mm barrel and 10mm mags and it should at least chamber and fire.

I've been hunting for 9mm slides and barrels and I've come up with very little, just used stuff, no retailers offering 1911 upper parts that I can find... Let me know if you find something.

This is Canada, currently the transfer of handguns is frozen by our leftist government. - dan
 
Fusion Firearms in the US makes complete slides. You could import through IRG. Might be worth a look. https://fusionfirearms.com/pistol-parts/slide-parts/slides

I've been tempted to get a 7" Fusion slide assembly just for fun.

But I have a 6" which is just about perfect for the 10mm.

Right, I forgot about the breech face. Maybe bringing parts in would be the smart play, thanks for the suggestions.

I was kind of hoping I'd be able to cobble something together but I guess if I do this I should do it right.

If you can find a 40 or 10mm slide, you can cobble it together. Could likely machine a 9mm or 38 super slide to work, but I've never tried it, so can't say for sure. I like those fusion ones in the picture though. - dan

I had asked too. Was told they are moving away from one-off, boutique jobs and general gunsmithing to higher margin CNC work.
 
I would definitely install a flat firing pin stop and a heavy mainspring. Even then I am not so sure about longevity. Heavy recoil springs do close to nothing, besides batter on the return.

I've done that mod on mine. It is worth it if you plan on shooting a steady amount of heavy loads.

These days I'm fine with standard factory spec stuff which is typically around the 45+p range. Given the amount of experience out there with 10mm now, standard set ups seem to be holding up fine to that type of usage.
 
I would certainly do the flat firing pin stop and don't radius it - fit it to the channel and use it as is for the best effect of slowing down the slide.

Also I don't see a problem using full power loads but would refrain from using the Nuclear loads such as Buffalo Bore, Underwood etc or else use them very sparingly.

Using a full length guide rod is a good mod to tame the recoil.

Ruger and other manufacturers do a lot to beef up their guns. A regular 5" setup done the same as a .45 is going to break slide stops relatively quickly and maybe worse with a diet of full power 10mm through it. I can't speak for every manufacturer but I have been down this road when 1911 10mms weren't really a thing like they are now. Since he is cobbling one together I do recommend doing whatever he can.

That would be a nice option, but no transfers are allowed. The OP has to assemble his 10mm from interchangeable parts.

BTW, I thought this was about 10mm sockets at first.

Agreed. It is a worthwhile upgrade and a no-brainer if you are building it up yourself.

Curious to know what Ruger did other than use a ramped, bull barrel, which isn't uncommon in all calibres these days. Sig completely redesigned the P220 for 10mm, but to my knowledge, most are using the same 1911 45 acp platform for 10mm, and just tinkering with springs. Strange that most don't use flat FPS in stock 10mms, but that seems to be the reality. I'm only aware that Springfield Armory added additional steel around the slide stop on all of their railed 1911s and used that fact to market their 10mm 1911s. Other than forging from modern steel alloys, I have not heard of anyone else beefing up their 1911 except LAR but that was for the 45 win mag. If you have other info i'd be interested in checking it out.

I get the sense that most folks aren't shooting steady full power 10mm in there 1911s these days, and reserving that task for their glocks and sigs.
 
^ full length guide rods, bull barrels and proper heat treating are all common now, no argument there. They are somewhat recent additions though. I guess my thoughts are stuck in the past. Since the frame can't be replaced legally I was recommending he over build. A cracked frame is worst case and would be a big headache. I can't say I shoot anything but full power 10mm but if he plans to shoot softer stuff it's all obviously less of a concern.
 
Kinda sounds like a Fusion top end might be the easy button here, I like the idea of a 6". It's obviously more involved than I had hoped, might give me something to do over the next while.
 
A couple of years ago I had the urge to do the conversion. Had a spare Norc 1911 sitting there so went ahead. All it took was barrel, proper extractor, heavier mainspring and of course mags..Novelty wore off before I had the chance to test fire. Decided to change back to 45 last year as I already had a couple of 10mms to play with. Never test fired it but not sure who the barrel maker was. Probably should take a wander over to the EE before the urge sets in again :)
