convert .45 1911 to 9mm

The slide needs to be changed due to the breech face being different. The barrel, ejector, extractor, mags and maybe the slide stop might need some work.
After twenty years of shooting I have learned it's best to buy a gun which was designed for a calibre. Eg, get a 1911 to shoot .45acp, get a BHP, Glock, Beretta,etc to shoot 9mm.
I've had three 1911's in 9mm and none were completely reliable with anything but roundnose ammo.

Pretty much the whole top end. Only mods to the frame is a new Ejector.

Im putting on a 9mm Top end on my 45acp and I only needed to change the Ejector.
 
I've got a 45 and 9mm, both Springfields... The 9mm was built that way from the beginning. I was at a 1911 site and all the advice pointed towards buying another 1911 specifically in 9mm format.

Yup, it costs more, but not a single jam or problem with the 9mm.

Cheers,

If you've already got a 1911 in .45 and want to take advantage of less expensive ammo, and maybe the wife doesn't want you to get another gun, a new top-end and ejector and you are good to go.

1. Reload & it's the same price. ;)

2. Glad my wife lets my buy what I want & when I want it. [Same for her though, too]. :D

And the other guy that said that going to 9mm was going to help him eliminate "flinch" just made me laugh out loud... :p
 
To make it easier for the conversion, back and forth, you can just mill the 45 slide out to use the 9mm ejector. It will function well with both calibers.
 
NAA I like you !!! LOL
The .45 ACP can be reloaded with a 152 grain lead bullet and as low as 3.5 grain of Bullseye at around 650 FPS.( need a lower rated recoil spring) That's .38 special target load range. Save your money, buy reloading equipment.

Curing fliching is a matter of learning the basics of shooting and to take the time to learn how to shoot. If you want to save, buy a .22 LR.
A 9MM will not cure your flinch or avoid you to develop bad habit.

This conversion is a waste of money for you, based on your need and goals.

The best reason... or maybe because I want to.

If you really want this and want it to work well I suggest that you have the frame cut for a ramped barrel configuration and then have the gunsmith (who specializes in 1911s) put together two different complete uppers both of which are matched to the frame.

Its not cheap, but it is just about the only way to be certain of it working properly. Probably not a cost savings but high coolness factor. :cool:
 
these are some good tips guys, thanks
i see on a previous post i left out that my indoor range does not allow anything over 9mm, i believe the backstop is not good enough for insurance reasons
 
I can see that, because a jacketed 9mm at 1300 fps is much easier to stop than a cast lead .45 at 700 fps.

I know you didn't make the rulez; it's just that dumb rules annoy me.

Splatter is 500 % right. This is dum. You should get involved in this Club admininstration and get rid of those Clowns. Better, find another range to shoot at.

:eek:

True its close to the same price, but you still have to take time to pick up all the damn brass. I cant wait to take my USP 9mm to SND nights and not have to play 300 round pick up.
