First time poster and new member.

I'm typically a Magnum dweeb. I love shooting .357 magnum in my snubbies and love shooting .44 Magnum in my black hawk and Tarus. Though I'm a big time fan of revolvers I still hold a great affinity for 1911s having shot my uncle's kimbers and Paras enough to love them. I'm a very utilitarian gun buyer, at least I think I am, and having watched my uncle buy setups from Caspian and Brownells to watch him put them together into these awesome custom jobs, well I'm a bit jealous to do so. Unfortunately my unlce is a diehard .45 ACP man and has stated his disinterest in my own little project, hopefully to be the first of many.

I'm looking build a 1911 that can be fired in 10mm but still retain a capacity for conversion. I don't want to buy a retail gun and then switch out some parts, that would be too easy. Instead I hope to take the reknowned 1911 and set it up so I can (with a variety of different barrells, slides, and what have you) fire a multitude of calibers in the single stack Government Colt Series 80. I have to have my 10mm having had a chance to fire the glock 20 and S&W 610 in 4" (my cousin's guns), unfortunately the size and feel of the 610 (while I love revolvers) doesn't make me all too keen on it when the possibility of project sits before me.

I plan to start off with:

A ramped 'Clark Custom' 1911 Auto Barrell in 10mm
Caspian arms 1911 Auto Reciever Colt Series 80, Smooth
Ambi Ext. Safety, Mccormick, Stainless
Drop-In Beavertail Grip Safety Wilson Combat 1911 Auto
Clark Custom 1911 Auto Recoil Spring Cover (to keep the spring from kinking)
And from Sarconics.com/cgm.html, a 1911 .45 Autobuilders kit (for parts, but I might just get a parts kit from Caspian soon as I can find the catalogue or just go ahead and order a new one)


The only troubles I'm running into is my lacking awareness of .45 ACP parts kits being compatible (as far as the really small stuff) with 10mm. I also need a slide for 10mm and am not sure if I should simply get a 10mm conversion kit to simply solve my barrel and slide issue (which I need help finding, I'm having the most impossible time with google). I haven't decided on a trigger but I remember Caspian having in their catalogue an extended trigger so I might just go with that, and having worked with my uncle I'm fairly able to reduce trigger pull (I like the light pulls and have a manual on how to do it), mind you this gun will be a plinker primarily for me. I realize the single tack will limit my round capacity but I don't ulitmately plan to CCW the gun, just have a great self made product of my own assembly and ambition.

For converting to .22lr (.22lr is just plain fun in a 1911 for me) there are plenty of available kits.
For 9mm (everytime I go the range I pickup a few hundred spent pieces in reloable condition, and have a bout 3k sitting at home) I figure there isn't so much a conversion kit as much as just getting the parts.
For S&W .40, wash and repeat 9mm except for the slide maybe.
For .45 ACP, wash and repeat.
I thought about .380 but can't bring myself to do it.

So in conclusion, I'd appreciate getting pointed in the direction of the best 1911 10mm conversion kits or at least slides. If anyone knows if the little parts in the parts kits for the .45 ACP are compatible for being used with 10mm (Caspian had a disclaimer on compatibility for .45 ACP). So for everyone who posts, thank you greatly. I think this gun could be an incredibly fun project for myself (probably wouldn't start it till June because I'm in law school and I make my disposable income at the Casinos and the 10mm alone looks like a quick grand), and after it is all said and done, I'd certainly share the wealth of knowledge.

Not till I'm a working professional will I get my Ruger GP in 3" converted to 10mm (granted after I got another one). I just love being able to change calibers.

The only parts that differ are in the slide and barrel. The 10mm firing pin is not the same as the .45 pin. When purchasing a 10mm slide you need to be sure to get the correct pin. EGW makes a firing pin retainer that helps slow the slide under 10mm recoil. I would recommend that also. I've built a 10mm 1911 from scratch and eventually decided that the 10mm is better at home in a Glock or S&W.

So why do you think the 10mm is better in a glock then in 1911 form? Been looking at both SVI and STI and feel that the STI kit would be a good choice from which to build from

I'd have to disagree...
I've owned S&W, Glock & 1911 style 10mm's and sold the S&W & Glock while keeping only the 1911. The only one I'd go back and buy again would be the Glock and that's only because I'd love to have the interchangeability with being able to use it with an M21 and suppressor use. Now, that being said....
Yes, building up your multi caliber 1911 pistol pltaform is going to be a pricey project but you knew that going so that's fine there....
EGW has always been a great source of info and parts for me. George has always been up front and easy to deal with. If you don't mind waiting on auction style purchases you can get some of his parts for lower prices via ebay, just so you are aware... I've used old Colt frames & slides in my builds so I cannot help you much with choosing a mfgr of those pieces there. For the smaller parts though again I would suggest you look at EGW, STI is fine, Ed Brown, Cylinder & Slide, Comminoli Custom (for a Tungsten guide rod)...
Myself, I still gravitate towards the non ramped style of bbl setp. Just a personal thing. I'm very comfortable working the parts myself so maybe it's easier for me than alot of others but I just don't find a need to go the route of the ramped setup. To each their own there...
McCormick makes a great safety. Nicely blended/dehorned/whatever but anymore I have fitted the Kimber style of ambi safety to all my 1911's. No modification to the grip is needed & I don't have to worry about the right side lever ever just falling off. You see I make 1911 grips for myself and for sale and sinceI have grips off and on frames all the time I have found the old style of ambi safety a pain in the rear to fit with having to mill the little relief on the underside, etc... I cannot tell you how many sets of highly figured/burled wood I have lost due to milling out the backside for that damned relief. The is highly unstable due to its burliness anyway so milling out that little area is just asking for more trouble than its worth... But I digress..... :blink:
Just about anything from Chip McCormick is good to go for me...
For recoild spring cover I'd use the same maker as the guide rod I wound up buying, just me... If you went with Tungsten though (for the guide rod) I wouldn't go with a tungstend spring cover as I would try to keep the mass as low as possible sliding back and forth... Just me again... Weight out front is great back having a bunch of weight sliding back and forth doesn't make much sense to me...
Your biggest/hardest part will be with the fitting of the sear, hammer, maybe disconnector, maybe trigger, maybe safety...maybe grip safety.... You may get really lucky and get parts that were not only designed to be mated together but actually do work work perfectly together. OR you may get a set that when put together give you hammer follow and put your 1911 into a full auto mode... Not Good.... Follow the install instructions on the Sear/Hammer you buy.... Hopefully the set you buy comes with a detailed set of instructions and or you have a good G'Smith you can send the pack of parts to help you out with.
I recently went with a Cylinder And Slide Ultra Match Hammer that not only looks killer but works like a dream on my Kimber... Good enought hat I am going to go ahead and order up another couple to try out in my Colt 10/40 Combat Elite & my Colt Defender...
STI makes a great Galss Filled Nylon Long Trigger if that long trigger works for you. I love it on my Colt 10mm and just put another in my Kimber. Looks great, Adjustable, works great and holds up for the long term... Fit and installation is pretty easy as well. Not too pricey either.
Oh, there is nothing wrong with a single stack 1911 for CCW. I carried my Colt 10mm off duty for nearly 13 years and never felt outgunned... It with a 9round mag in it and 2 back up mags and I always felt adequately armed... But that's just me. It isn't always about how many rounds you have on you...
Good luck with your project... Give some thought to 24/7 Express Sights... I switched to them after retirement and love them....

Does anyone have a website (or telephone # for that matter) where I can contact EGW? I would like to discuss obtaining a pair of flat-bottomed, stainless-steel firing pin retainers for both my IAI Javalina and my DW Razorback.

Thanks in advance,

Scott

Not true if you're talking about Caspian slides. They now make all of their slides with 38 Super/9mm firing pin holes to reduce primer flow.

The difference between the .45 slide and the 10mm/40 slide is the width of the breach face cut from firing pin hole to the left side. All 1911 slides have the same spacing from the firing pin hole to the extractor tunnel. R,
