Your question seems to be; "why"?
Exactly . Spot On
Well, to that I would say; "Why Not".
That's what I am curious to know .
Just because it's a 1911 doesn't mean it should only fire .45 ACP. 1911's today are made in many different calibers like 9mm, 40 S&W, 38 Super, etc.
I am not saying that a 1911 pistol should only chamber & fire .45 ACP rounds . And I am not saying that there is something wrong if people buy and use a 1911 which is chambered for rounds other than .45 ACP . For example , if someone buys a 1911 chambered in .22 LR ( or an .22 LR adapter kit ) and uses it for plinking , so to keep the ammo costs down ; I understand . What I do not understand is the logic behind using a high performance round such .357 Mag in pistol which has 100 + year old design and technology . Now while typing this and the rest of my post my tone is not skeptical ; it's just the curiosity of a firearm novice .
The .357 Mag is a damn good cartridge as far as handgun cartridges go. It is powerful, flat shooting and in most handguns, quite accurate. It will significantly out perform the .45 ACP in almost every way. It certainly has more velocity and muzzle energy than the .45 ACP. You are also going to get a little better performance out of the cartridge in a semi-auto rather than in a revolver, as there is no barrel-cylinder gap in the semi-auto.
There is no denying that a.357 Mag performs better that a .45 ACP . And also agreeing with the fact that in a semi auto .357 Mag will get more barrel pressure and range due to the absence of the cylinder gap , which is present in any revolver . But , in a revolver the barrel is fixed to the frame , where as in a 1911 , it has a locked breech barrel , so the accuracy of the round will be affected . It may not be much , but still a fixed barrel firearm would be more accurate than a locked breech barrel firearm . I am not implying that 1911s are inaccurate , I am saying a Model 686 revolver would be more accurate .
What's so great about the 1911 today? It is a slim, generally reliable, semi-auto that can be carried concealed relatively easily (with the right holster and the right belt).
But a 1911 is a single action pistol . In a defensive situation , I would prefer a double action firearm , be it a revolver or a pistol . I look at handguns as a defensive tools . I prefer using a rifle or a long gun for recreational shooting . It's not that I find anything wrong with people using a handgun for recreational shooting , it's just that I primarily look at them at defensive tools .
Also the 1911 does not have ambidextrous controls for safety or magazine release . Now , why would this bother me , a right handed person ?
Well , what if I get involved in a fist fight and end up injuring my right arm to the extent that I can't use it to draw my weapon and defend myself . Then I have to use my left hand to fire it . But I will have problems , trying to fire with my left hand , when my gun is designed to used by a right handed person . And while I am struggling with my index finger to get the Safety into "Off" mode , my attacker would have pumped a magazine full of rounds into me . Same can be said the magazine release .
Now having said all these , the question is would I like to own a 1911 pistol ?
The answer would be , I would LOVE to own a Ed Brown 1911 from their Kobra Series and Signature Series each, but as long as it's the 5" Government Model and chambers a .45 ACP round . Just my preference . And they would be my collectable items not defensive tool . I wouldn't be using them a daily carry gun , because I would be too much worried about damaging the finish on the slide & frame every time I take them in & out of the holster .
Another question , is that would I like to own a Coonan 1911 which chambers a .357 Mag ?
The answer would be ... Maybe , if I am sure it would fetch me more money than I paid for it after 3 - 4 years . Or else no .
About Revolver vs pistols , yes , it depends on person to person . I would not go on the Pros & Cons of either of them as it would be Off Topic . Maybe some other thread , some other day . I would just say that I would like to own a Desert Eagle .50 AE , but I would love to own a Ruger Redhawk Alaskan which chambers the .454 Casull round .
And about my love for GLOCKs , I don't have any fascination of them . Looks wise they look like , they have carved out of big pieces of charcoal . I am hoping I am not offending any GLOCK owners / lovers , when I say they look like pieces charcoal , but kept side by side with a Ed Brown Kobra , they sort of do .
I would buy a GLOCK as defensive tool because I like their " Safe Action " mechanism . I would like a GLOCK for it's ease of field striping . I would like a GLOCK because they have the least non ammo related malfunctions .
And other words , I would compare GLOCK firearms to Toyota vehicles . Toyota vehicles are good reliable vehicle to get you from point A to B , but they do not have the best ride quality , or the best handling , or the most horse power . They are good over all vehicles or transportation tools . Similarly GLOCKs in my view are good overall firearms , but not the last word in firearms .
Thanks for posting the videos & photos , explaining the importance of grip and shooting stance to control the recoil of the firearm . I was not saying that a 1911 chambered in .357 Mag would have a uncontrollable recoil and sometime the gun may even fly off the hand of the shooter . I was just saying the recoil of a .357 Mag 1911 would be different from a .45 ACP 1911 .
@ Baljit
Don't worry , you did not offend me by calling GLOCK firearms are junk . First of all , I don't own a GLOCK , and from the look of things ( read Gun Laws of India ), I never will . And even in a one in a million chance , if I ever do own a GLOCK , it would be just a tool for me ; like the hammer in my tool box . The day , the gun will malfunction or get obsolute , I will replace it with a better version . No attachments to it , of any sort , whatsoever .
By the way , do post the pics of your Coonan when you get it , and if possible a video like XL_Target mentioned .
