"The First … The Smallest … Soon to be copied by everyone:
Get a good look at the new Springfield Armory EMP, because soon it will be copied by everyone. And when you see their pistols that look almost like ours, you will say to yourself, "You know ... that looks a lot like a Springfield Armory EMP."
Get a good look at a whole new class of pistol -- the short-action 1911. The new Springfield Armory 9mm Enhanced Micro Pistol (EMP) is the first production 1911 made from the ground up to shoot short cartridges like 9mm, 40 S&W and 45 GAP. The result? The smallest, most concealable 1911 you can buy.
Previously, when 1911s were chambered for short-action calibers like the 9mm, 40 S&W and 45 GAP, this was done on guns built around the longer 45 ACP cartridge (Essentially, long-action 1911s). Spacers were placed in the magazine to align the shorter cartridges. The EMP is the first production 1911 designed specifically for these shorter cartridges.
The world got its first glimpse of the short-action 1911 in 2005 with a prototype Springfield gun called the "Defender." Chambered in 45 GAP, this rare gun received rave reviews from numerous firearms publications. We decided to launch this new class of 1911 in the more popular 9mm caliber in the EMP.
In order to shrink down the frame and slide of the 9mm EMP Springfield engineers had to redesign a total of 15 different parts to accommodate the change and enhance the 1911's performance specifically for short-action pistol cartridges.
Here is a comparison between the micro compact and the EMP"
