    Using the M45/MEUSOC/CQBP as the example, majority of frames are rebuilt using WWII frames. With newer crops of Springfield and Caspian frames/slides, and now Colt's new contract, what is the longevity of a 1911 slide put through the deployment/s of Force Recon and MARSOC? Will these new Colt frames last till year 2079?

    Can slides be rebuilt like the frames (not seeing pics of any WWII era slides on any of the PWS 1911's).

    I've heard different figures per deployment, like 15,000 rounds fired up to 80,000 (Wikipedia shows possible rebuild after 10,000 rounds?). On the new contract M45 Colt Rail pistols, how long will the factory slide/internals last? Are slides, internals, etc. going for more than one deployment, or just rebuilt as preventative?

    I'm guessing the new Colt M45 CQBP are replacing all the old stock? Hopefully the new Colt's will survive (seen cracked frame pics). All the WWII Colt frames being "put out to pasture", put in storage, staying in rotation?

    I've been very enamored lately with all the M45 CQBP/MEUSOC 1911's. What is the truth about the Kimber "Det-1"/Warriors? Were they destroyed, sold, still used?

    Borrowed picture for fun, WWII Colt frame with Springer slide:

    They are getting all new frames, note the rail.

    as to lifespan, you know what they say.

    lock a Marine in an empty room with a pair of 2" ball bearings and in 1/2 hour he'll break one and lose the other.

    If they are supposed to last 10,000 rounds, expect the Marines to get replacements when they are at 75,000 rounds.

    In all seriousness, I would expect a long life.

    In most recent book of 1911 10k rebuilds not always done if things look ok,
    some frames est 500k.
    Suspect slides wear faster than frames on average.

    Marines will destroy anything you let them, just as long as the politicians take off the leash.

    breadman- isn't that the truth!
    I suspect like all gi guns after deployments they will be TI'd- tech inspected- and if within specs go right back out to troops. if not rebuilt- they will just use these and other small arms to the point of destruction.

    When I qualified with the 45 (USMC) the newest gun in our armory was made in 1945.
    I shot newer 45's after that but qualified with an old clunker that was probably rebuilt many times.

    as far as box stock 1911a1's the government did not procure ANY for military use after 1945. the youngest frame in service would be 1945. perhaps a VERY small number of replacment frames for the meu soc program and the very small batches of det1 kimbers but all the other 1911 type guns are at least 67 years old.

    I suspect it would be cheaper to buy new guns these days than put them through a depot rebuild program like they used to.

    Gotta love the Norinco! I have three 1911s and my Norinco is my front line off-duty gun. I just rub my Colt and leave it in the box...lol

    I remember my Paris Island .45.... Wow was that thing loose!! Still shot great. Would love to seen the list of marine's over the year who shot it.

    I don't know much about the 1911s that the Marines use, but I do know that they have a quite a few Springfield Pros and and complete Springfield guns with USMC serial numbers.

    How many of the original circa 1945 frames are still out there? Probably a bunch.

    I've done some Googling on the Rail gun they decided to use and doesn't look too hot.

    Unless they are damaged by outright abuse, they should be able to serve the great grandchildren of the Marines that they are first issued to. A 1911 frame lasts almost forever. A properly heat treated slide will last at least a couple hundred thousand rounds (most WWII slides were not fully heat treated). You can wear them out, but it's not easy even when the taxpayers are paying for the ammo.

    There are stories of gamers that have gone thru a couple of barrels and slides with the amount of rounds that they shoot. And we're talking 5K rounds per month, averaging. And these are on STI or SVI built 2011s.
