Firearms and Training has posted an essay written by a Marine who was badly wounded in combat, and only realized his mistake after taking tactical training courses.

The reason for this belief of mine is fairly simple: When I was engaged in combat the day I was wounded, I made several critical mistakes resulting either from training scars or from simply not being trained how to do something in a certain manner (if at all). I know that training, tactics and procedures (TTPs) and SOPs have changed greatly over the past 6 years since I was wounded, but I guarantee that they are still lacking enough to where I would strongly advise anyone who is planning on going into harms way, either on foreign soil or here domestically in our own nation's cities, to reach out to the private sector for some enhanced weapons training. I believe that it could save lives, and could prevent a lot of men and women from being needlessly wounded (not all by any means, but quite a few such as myself).

He does make it clear that he does blame the Marine training for his mistakes.

Somebody at Marine HQ realized that if you buy a lot of M1911A1 frames, you are probably are going to need slides to go with them!

The Marine Corps System Command (MCSC)intends to issue a solicitation number M67854-09-R-1146 for 1800 M45 .45 cal pistol slides. The Government anticipates a resulting firm fixed price contract for this commercial procurement ...

Slide blueprints available from navy.mil

The slides are for the MEU(SOC) pistols that are used by Force Recon. Daniel Watters noticed that they are referring to the pistols as the M45. Daniel, who knows far more about these things than I do, is not sure if that is an official designation or a colloquial one. Anyone heard of the M45 designation before?

Thanks to Daniel for the link and info.

Daniel E. Watters, who is always vigilant, alerted me to the fact that the Marines are looking to procure M1911A1 frames. The frames are for the MEU(SOC) pistols that are used by Force Recon.

Up till now they have been using surplus 1911 frames. I guess the supply of quality surplus frames in their inventory has finally run out, nearly twenty years after 1911 pistol was replaced by the M9.

The Colt IAR is Colt’s entry in the Marine IAR competition for a lightweight automatic rifle to replace the SAW in certain situations. It is an interesting weapon.

Under the barrel you can see a hefty heatsink. This is used to prevent cook-offs (when the primer of a chambered round is ignited by a hot chamber). It weights 9.5 lbs and has a 16″ barrel.

It looks like the barrel may be be changed by simply removing the bolt you can see just in front of the magazine well.

Surprisingly the rifle/machine gun does not use a gas piston and uses the AR-15/M16 direct gas impingement system.

The above photo does show a Magpul PMAG but the Marines have specified that the IAR must be compatible with 30 USGI magazines, so it is unlikely the military will be adopting PMAGs, even in a limited role with the IAR.

Other IAR entries can operate with either an open bolt, in automatic fire, or closed bolt in semi automatic mode. This allows the accuracy benefits of a closed bolt with the heat reduction and reduced chance of a cook off of a closed bolt. I am not sure if this weapon has this feature.

Colt already have a lightweight automatic rifle, the Colt Automatic Rifle (CAR), which itself may meet the Marines requirements. I do not know if the Colt IAR has anything in common with the CAR, other than the shared AR-15 heritage.
