Well, it was sufficiently obvious that we were getting two or three of this same question every week. :rolleyes:

So what is the difference????



Just kidding. I just love when someone who knows nothing about firearms tries to act like they are an expert. I had my 1911 on one day when someone looked at it and said, "So how do you like your Glock?"

That was a bit different but thanks for the sticky...now if we can just get people to read it.

Maybe people will read it if we change the name of the thread to "Nude Pix of Hot Chix" or something catchy like that. :dope:

thanks...

thank you.

How does these functions...

1. "GI style high ejection port" vs. "lowered ejection port" ?
and
2. having a polished throat/ramp(?) in feeding to chamber...esp. LWC re-loads? Does the GI or the Mil-Spec have this polshed ramp?

...affect realiabilty at seven yards range.

Military specs called for vertical(or near vertical)ejection, hence the taller port. They can be tuned to be just as reliable as a lowered port, they are just less forgiving...and sometimes meaner to your brass ;).

I have gotten 100% reliability from every G.I. model I've had, with bullet shapes of all kinds.

Alright so I'll bite...

I have been hanging around the this forum for a while....and I think that I am going to purchase a Mil-Spec, in stainless. It is in my budget and it sounds like the perfect intro to 1911 pistols. Thanks. :)

Did My Homework

While it may be sad that a dedicated thread had to be created to distinguish the differences between the Springfield models, some of the external differences are subtle - especially to someone who hasn't done their homework.

I've been looking at getting an "entry-level" 1911 for quite a long time. I spend months just researching manufacturers and models - comparing one against the other. I finally settled on the Springfield Mil-Spec, desiring the little extras in this model over the "G.I." one.

Now I don't know about gun shows in other areas, but at the shows around the Tampa, FL area, I see several dealers with the G.I. models in their green plastic cases, but very few of the Mil-Specs. And even the G.I. cases have the words "Mil-Spec" printed on them, further adding to the confusion. At one point in my hunt for a Mil-Spec, my wife was convinced that the G.I. "Mil-Spec" guns were the ones I was looking for. When I finally found a table with a true Mil-Spec on it, I was able to point out the subtle external differences to her so she'd know the difference.

I've so far put 450 rounds through my Mil-Spec since I bought it this past weekend, and only had one failure to feed problem. I really like this gun, and it was worth every penny.

I appreciate the effort that went into the detail of this comparison by DSK and XavierBreath.

At this point I think I'm going to do the SA GI. I was also offered an Auto Ordnance with a list price higher by $80, but a local dealer here offered me the AO for about $20 less than the SA GI. The GI seems to be at about $425 near Tampa.

Ah yes the GI 1911

Just tried to squeeze the ol' budget for one of these beauties, but alas no blood left in the turnip this year. I can dream though. :bawling:

What about function?

I read this thread and I appreciate the outward differences but no one explains the functional differences.

Why is the Mil-spec more money normally? Does it function better than the GI Model?
