Default WW1 Era Slides M1911

Hi all; I was delighted when I received my Colt M1911 1918 issue pistol. Field grade. It’s one of the Army museum pistols where the slide actually matches the frame, extremely fortunate. However, these slides were never heat treated and there is a risk of cracking the slide. I didn’t want a $950 collectible paperweight that I couldn’t shoot so I weighed my options. The answer was a USGI hard slide.

I found one on eBay for $275; it’s a post-WW2 replacement slide with Colt commercial rollmarks, parkerized. Some members on this forum received such a slide with their pistol. I ordered new slide parts from Numrich and took it to my gunsmith Chuck, at 1911 Academy in McKinney, TX. He did a great job, tuned the new extractor to the new slide and test fired it. Worked like a charm.

I thought I’d share this idea with the other M1911 owners out there with matching slides; it’s better to go through this step now before cracking your original slide. If you do, you’ll need to buy a new slide anyway. Better to have both. Here’s the before and after pics.....

Original slide.

Just so you know the frames weren't heat treated either. I understand you want to shoot it but if you want a shooter with less likelihood of cracking you're gonna need a 1911A1.

If I had a 1911 I'd shoot a box or two of ammo a year and call it done. If someone wants a dedicated shooter without risk of damage to the frame or slide then they need a slide and frame that's been heat treated.

Razor, great point; I had read somewhere that frames are less likely to crack than slides, as to why that claim was made I have no idea. For my 2500 round a year 1911, I値l save that for my Dan Wesson stainless. This will get 200 a year max.

Anyone make a 1911 load that is down loaded so you really minimize the risk of slide damage?

I have the opposite issue. I got a beautiful Field Grade 1913 Colt frame with a Remington Rand slide. Even though it is only spot hardened, is is stronger than the early versions. I am searching for an early Colt slide for when it is in display mode and switch out to the RR when I want to have fun.

Dan, I saw a couple of early colt M1911 slides on eBay and Gunbroker when I was looking around for my hard slide. Check it out, I知 sure you値l have good luck! Proper fitting of parts for the new slide and existing barrel, you値l have the same issue as me...

I completely agree. And I understand wanting to shoot the old warhorse. If I had received a 1911 I would want to shoot it a little bit too. Nothing wrong with what you've done by the way. I understand completely.
