Springs are cheap, but why replace parts you don't have to replace?
"Cocked and Locked" Question

It's like this:
Someone once asked what oil I use in my vehicles. I use brand X. How often do you change it, was the next question. Every XXXX miles. You're wasting money, was the response. Maybe, but I'll never get in trouble changing my oil (or springs) too often.

Fixed it for ya! The "Mk IV/Series '70" was a designation for a gun with a belled barrel at the muzzle and a corresponding finger-leafed collet barrel bushing. It is often and mistakenly (even by Colt nowadays) used as a proxy for the lack of a firing pin safety system. This is not what it was. The Series '70 used the same (lack of safety) firing pin system as all 1911's since birth.
A Series '70 gun will fire under the above scenario, but so will any Colt made before 1983, not just the Series '70 guns. Small detail, but it's worth getting the terminology correct

there is another way to keep a 1911?
With regards to the new Sig P238.... (the reason i'm asking is that while it looks like a mini-1911, it may not have all the same safety features)...
1. Does the Sig p238 have a firing pin safety?
2. The Sig P238 does not have a grip safety.....so...if the hammer falls for some mechanical failure...will gun go off....assuming that the trigger is NOT pulled?
3. Is there a half-notch or quarter notch on the Sig p238?

1. Yes.
2. No.
3. No. They use a bump on the hammer to slow the fall similar to the later Colts with no half cock intercept notch. The half-cock notch is not a safety notch. And it is dangerous to carry a 1911 loaded with the hammer halfway down in the intercept notch anyway.
A grip safety on a 1911 has exactly nothing to do with stopping a gun from going off if the hammer falls and the sear misses the intercept notch.
All the original 1911 grip safety does is block the trigger stirrup from pushing the sear back out of the way. Later designs may use it to unlock the firing pin lock as well.

My 1911s stay cocked and locked unless cleaning or firing.
Never personally known of it doing anything detrimental to one.

if being stored in a cocked and locked condition harms a firearm, said firearm is not something you would want to consider trusting your life with

Im not worried about the 32 lb mainspring in my Hi Power to get weak. It is already over sprung.

Seems like the vote is in everyone start carrying cocked, locked and loaded
I know of police officer co-workers who have carried cocked and locked Colt .45 1911s for 30 years in their duty holsters. They've never changed any springs. The guns are in sub-zero and upper 90s temperatures. They are subjected to rain and snow and occasional Diet Pepsi spills. The pistols are fired regularly (4-6 times a year) and have never failed.

"As far as I know, the thumb safety and grip safety impede movement of the hammer via the trigger assembly/sear, so if the sear were to shatter the thumb safety and grip safety wouldn't do anything."
You are wrong there but that is a good thing.
The manual safety also blocks the hammer in it's own way.
If the hammer should fall, and for some reason the half cock or intercept notch does not stop it's fall, the hammer will hit a part of the thumb safety before it contacts the firing pin, and it will have to push the safety to the off position before it can hit the firing pin.

On some 1911's , depending on how everything is fitted, the safety may completely stop the fall of the hammer.
On some it will only slow it down but on most of these it may slow it down enough to stop the AD.
Having a good positive detent on the manual safety is important. It makes accidental deactivation of the safety difficult and it makes the pistol safer in the event of a sear failure.
The more difficult it is for the safety to be placed in the off position the less likely it can be forced to the off position by a hammer fall.
