9mm 1911 question

No, the feed ramps are cut at different angles, and they have different sized ejectors.

Reliability and accuracy are subject to a lot of factors, just like any gun. But they're not inherently inaccurate or unreliable

That I'm not exactly sure on, I know safeties and grips and triggers will, but I think I've seen slide stops marked different calibers. So there may be one or two parts that won't interchange. Best bet is to call the manufacturer of the replacement part you plan on putting in.

The best way to make a 9mm 1911 reliable is to ditch the goofy mags that use a spacer in the back of a 38 Super design and instead use a spacer in the front, a la the Springfield/Leatham design.

All of the bottom end parts of a 45 ACP 1911 will work in a 9mm 1911 except for the longer ejector needed by the 9mm and the slide stop - the 9mm version has a longer internal extension to aid in making reliable contact with the narrower magazine follower. The bottom end itself will be machined differently for feed amp angle needed by the shorter cartridge, technically, although many don't bother. If the frame is set up for ramped barrels, then the frame can be the same and the ramp differences confined to the barrel itself.

Different top end parts include slide itself (smaller breechface), firing pin, extractor, and barrel.

I have to confess I never understood the obsession with chambering the 1911 in 9mm - to my thinking that's what the Browning High Power is.

And firing pin stop. Many 1911s chambered in .45ACP use the smaller diameter 9mm firing pin so that specific part is sometimes shared.

Agreed that 9mm 1911s are far more finicky than .45ACP.

The High Power does not even feel close to the same as a 1911 does in the hand, in my opinion.

Some people really, reallylike 1911's and really, really like the 9mm.

9mmepiphany's OAL statement makes sense, I didn't really think about that.

I do, actually. I love he ergonomics of the 1911, and a 9mm is so much cheaper to shoot, plus with the weight, I would assume recoil is nigh unto negligible, and it's fairly easy to conceal.

Because although awesome, the HiPower is not a 1911.

And as much as I love .45ACP, 9mm 1911s are sweet shooters.

My EMP for example, is amazing.

I have Kimber 1911 in 9MM with just under 6500 rounds fired thru it. No malfunctions of any kind and very good accuracy.

I love 1911s, and I love Browning Hipowers. They are not the same in any way.
Just this year I picked up an STI Spartan in 9mm. It had to make one trip back to STI to fix an issue, but after that it's been 100% reliable, accurate, and fun to shoot.
I use Metalform mags, no problems.
