The SIG-Sauer P228 pistol was developed from the larger SIG-Sauer P226 pistol in 1989 in the same way as the earlier P225 pistol had been developed from P220 – which means that the designers basically chopped some length from the barrel and slide, as well as from the grip. The overall shape of the P228 also was made slightly less angular and more suited for concealed carry. In around 1991 the P228 was adopted by US Armed forces as the M11 pistol, and is issued to Military Police and some other units. The P228 is also a highly popular police and civilian sidearm and is widely issued to law enforcement forces in Europe and the USA. The P229, which was developed especially for the US market and is assembled in the USA using both German and US-made parts, is technically similar to the P228 except for the heavier slide, made by machining a bar of steel as opposed to the P228 slide, which is made by stamping and forming from sheet steel. The heavier slide on the P229 is necessary because of the more powerful ammunition used in this pistol. P229 pistols also can be adapted to any of three calibers (9mm, .357 and .40) by switching the barrel and return spring; P228 pistols are 9mm only and cannot be converted to other calibers.
Like the larger P226, the P228 and P229 pistols are available in aluminium frame/steel slide or stainless steel frame and slide versions, with standard DA or DAO triggers.

How to field- strip (disassemble) P228 and P229: 1) remove the magazine by pressing the magazine release button; 2) check that the chamber is empty; 3) pull the slide all the way back and lock it there with the slide stop; 4) rotate down the disassembly lever, which is located at the left side of the frame, above the trigger; 5) release the slide and carefully push it forward, and out of the frame; 6) remove the return spring assembly from below the barrel; 7) remove the barrel from the slide.
Reassemble in reverse order.
