I would like to convert a 1911 to either 10mm or .357 sig. What would be involoved in this? The pistol is currently a .45...duh

silly me. I would like to know about mags, barrels, any other changes that would need to be made. Thanks ahead of time,

A new top end. Slide, barrel, etc.

Might actually be cheaper to buy a .40 Kimber and have Barsto make you a barrel.

The frame ramp is different on the 45. I've seen them work but I wouldn't bet my life on that gun. The ramp on the 10/9/38super are the same. If you had a base gun in one of those caliber the conversion would be easier. George at EGW could redo the ramp but then you probably couldn't return the gun to 45.

 

[Rocklobster]

Haven't researched .357 Sig,but you're not going to be able to convert a standard .45 to 10mm-the 10mm frame & slide are larger & beefier than the .45.

.40 Super or .400 Cor-Bon you can do-barrel,recoil spring.

Just what I thought all along......

Rocklobster,

"Haven't researched .357 Sig,but you're not going to be able to convert a standard .45 to 10mm-the 10mm frame & slide are larger & beefier than the .45."

Thanks!
Always nice to gain valuable knowledge from an experienced gunsmith.
15 years of 1911 'smithing, and I was not aware of the size differences!
Well, never too old to learn from a pro such as your self.

aw come on chuck
you probably didn't know that
BHP slides are hard either.

Good! Glad I could help you geniuses out!

 

[Dave Sample]

Amen Pistolwrench. These conversion topics are a waste of time. If these guys have this kind of money to throw away, why don't they just go out and buy what they want. The Lobster is trying to impersonate a human being and can't quite pull it off. I doubt if he even owns a gun, much less a 1911. "You know if you're a ******* if......"

 

[Rocklobster]

Thank you very much!Coming from a leading member of a group whom are all obviously quite experienced at impersonating human beings,I take that as a compliment!

"You know your a moron if..."

Rock

I hate to give it to you,
But that was pretty good.

NOT Genius, just guys that have made there living for 15+ years working on guns. And sometime that is not an indicator of work either.

any chance your offering some solid insights and playing nicly?? Just curious

This is an inaccurate statement. The slide/frame differ only in the dimensions of the breach face cut and the feed ramp. Not a good conversion, certainly, but a new top half with some EXPERT feedramp work (weld/recut), it can be done.

All right Rock, fun's over. If you've got something to offer that is accurate and contributes to the pool of knowledge available to the board, please do offer it. But don't try to bluff your way around here. You came into someone's house when you joined this board. You are a visitor here just as the rest of us are. We don't go visiting someone's home and hem the host up in a corner by insulting either his or his guest's intelligence and behaving in an arrogant manner. Same rules apply here. We are all here to learn and have fun. Even those of us who are very experienced hobbyists or pros still learn from each other.

GOOD post Bill

the only difference on the 10 mm frame, and I could be wrong it happens a LOT

is they knew it would get pounded so the cut out the rail above the slide lock as a premptive (clearly spelled wrong

) strike.

I think I remember a long ago gun writer article that the 10 mm frame was heavier?

George, et al.
1. There has been a lot said lately about the difference in feed ramp from .45 to smaller calibers. A friend has a .38 Super upper on a Gold Cup receiver with no change but the ejector. (He likes the wide trigger, ick.) It feeds fine. Is he just lucky or is the problem kind of theoretical? Another local converted a .38 Super to .45, years ago when there was little if any .38 hollowpoint. I don't recall how much feedway work was required, but the gun ran.

2. EGW used to catalog a steel feed ramp insert for mechanical fit instead of welding. I *think* it was EGW. I do not see it in Brownells or the EGW site? Is it gone? Why?

 

[Rocklobster]

OK.Having been a computer mechanic before 'smithing,I have developed the old "x in,x out" habit. My earlier snide remarks about the lengthy spring-related posts may have been uncalled for.But,if I want to read a few chapters of Kuhnhausen's,or Hallock's,or whatever textbook,I'll get 'em out and read 'em!'Scuse me,I'll play nice!OK?

 

[BBBBill]

Good enough for me.

Now let's get back to the business at hand; sharing, learning, having some fun.

 

[George Smith]

Bill, I think we should put rock on
"double secret probation" if you remember that from animal house

Jim
if you measure from the top of the rail to the bottom of an "average" feed ramp a 9mm 38 stupid 40 10mm... will be around .250 ish, I do not know for sure the corrosponding angle but it is around 31 deg.

the 45 ramp is .375 ish and works better on agressive hollowpoints at .420. Sometimes a non ramped barrel in 9mm catagory will overhang the ramp cut on a 45 frame.

If you took a super ramp frame and shot .45 ball ammo and espically with 7 roung mags you would probably be a happy camper. With a large nose hollow point with 8 rd. you may very well get nose dives.

Brownells needs to make 750. profit per colum inch in the 175+ thousand catalogs they send out. If they do not profit that amount, they drop the part like a bad habbit. We still make the ramp and unfortunatly our web sight does not reflect all the 175 ish parts we make. I am not sure but Ned or Chuck may offer one for sale also?

Oh my gawd!!!

Not Double Secret Probation<> it really wasnt that bad, and he promised to play nice after that almost apology.

 

[Dave Sample]

If you own Ken's book, look on page 110 and note the grips on the bottle opener.He is a personal friend of mine and he gave me those grips some 15 years ago. I put them on my carry Commander from time to time and still think they are pretty obnoxious.I am opinionated, arrogant,and highly skilled. I do not try to be a bunghole like you, lobster. The flame I cause is not intentional,just a bad reaction from the other know-it-alls. You need to crawl back in that pot and go back to the bottom for a while. We call that "The Deep Six" treatment.

 

[Rocklobster]

Arghhh! Not Double Secret Probation!

A "bunghole,according to Webster's,is "a hole in a barrel or vat,used for drawing off the contents,and closed with a bung."

Please let me assure you that I have never had aspirations of being such an object,believe me.
