Springfield's MilSpec vs. GI 1911

[Bronson7]

Does anyone know the difference(s) between Springfield's Mil Spec and the GI issue 1911s? Other than the sights and grips, I can't see any difference on their website. Thanks.

WW2 (GI) Model: Pistol closely replicates the basic 1911A1 as used by the US military for seven decades. Features:
high wall ("narrow") ejection port
low profile GI sights
lanyard loop on mainspring housing
vertical cocking serrations on slide

Mil-Spec: Pre-dated the G.I. model, adds some popular features/upgrades
stainless barrel and bushing (some models)
loaded chamber indicator (some models)
lowered and flared ejection port
high profile 3-dot sights
beveled magazine well
loss of the lanyard loop on mainspring housing
forward-raked cocking serrations on slide

My son just picked up the Mil-Spec over the GI. Felt better with the better sights, lowered ejection port and stainless barrel.
