What I said
You do things your way.No problem
I'll suggest reaching for heavier recoil springs is not the best plan.
Heavy springs have a couple of problems.One,there is a choreography issue.
The magazine needs a certain amount of time to lift the column of cartridges up to the mag feed lips.A heavy recoil spring speeds up the slide....Which results in problem two.
The 1911 is designed with a reasonable amount of steel to deal with stopping the rearward motion of the recoiling slide and barrel.
Its far less robust when stopping the forward motion of the slide. I'm not a pro 1911 smith. Amateur hobbyist still learning would be closer. IMO,I'll go 2 lbs heavier than JMB intended with a recoil spring if I have reason to. I get ther by installing a 4 lb over spring, At the point the slide stays open most of the time with the 4lb over spring, for myself,thats a limit. Then I go back to the 2 lb over spring. The slide should reliably hold back.
FWIW,the above suggestion will typically select a 16 or 18 lb spring.
I've seen folks recommend and choose 24 lb springs.(Not necessarily for the Super)
My point is heavy recoil springs are a path to a short lived gun.
If you reread my post,I think you'll fing my tone more about "For myself,I choose" or "you do as you wish,my advice would be"
Point by point you selectively edit/quote,and then spin an attack.
You talk out both sides of your face about Major Power.
And the red print. Whats that about? Do you see anyone else doing that? Its weird. Are you needing attention?
I gave my best answer to the OP. You can give your best answer to the OP.
We can disagree. That's OK.
Its an open page. There is room for both of us. A red type tirade?
That's just weird. Are you OK?
This is the OP. This is what I was answering. If you have some freak agenda,thats OK. But please leave me out of it,thanks.
Are you feeling insecure?
The OP:
I have a Colt .38 Super 1911 in bright stainless. It's a 2008 gun. The Internet says I owe it to Mexicans failing to buy as many guns as Colt produced for them.
The odds that I will ever use this gun for self-defense are about like the odds that California will put an AK-47 on its flag, but I still want to make some defensive rounds. No good reason at all.
Can anyone give me advice regarding what the factory chamber can handle? I don't know much about it. Are there aftermarket barrels that are safer for hottish loads?
---------------------------------------------------------------
My first 1911 was a Super,about 30 years ago. I owned a Ben Jones Guncraft open race gun in 38 Super. I gave it to my brother. I have access to it as a model. I suspect you don't know who Ben Jones is,or what kind of 1911he built.
I don't limit the 38 Super.
I'm in process building a Caspian double stack with a Commander length ST Tru-bore comp barrel. I expect to load it to the 40,000 psi range.
I've learned some about the 1911 by building them. I have an idea about what helps them live.
We have an OP shooter who is new to his 38 Super talking HiVel loads with Blue Dot. Been there,done that,got the tee shirt and a junked Clark barrel.
He won't screw anything up with CorBon or Buffalo Bore or factory loads.
The OP said he just wanted SD loads before the velocity thing kicked in.
I did not tell him what he could or could not do.
I told him to ask himself what he is trying to achieve and why.
I don't even need to read his answer. The answer is for him. Its no skin off my nose.
I clearly said I'm an amateur hobbyist.
The comped double stack Caspian I built out of reclaimed parts runs like a watch with 1450 fps 124 gr Montana Gold and Power Pistol with a 12 lb recoil spring.High speed video showed that the flattest shooting combination.
What have you built with your hands?
