    Goto this link-----> Springfield Armory
    Click on a model of 1911, say the GI .45
    Click on 1911 manual
    Goto pages 13-17 of the manual

    Your answer lies there.

    I have been away for a couple of days & just now seeing this...

    ILS stands for Internal Locking System & is SA's mainspring locking mechanism.
    It is basically a pin block that locks the mainspring and prevents the gun from cocking. It is turned 'on' & 'off' by a key thingy that comes with the gun.

    One of the very 1st things that I did to my SA Loaded was to remove the entire mainspring & ILS assembly and replace with a Smith & Alexander mainspring housing & magwell combo. Replaced the SA mainspring with a 19# Wolff mainspring.

    Do all their models come with this? I've been wanting a 1911 and will most likely get one this coming Jan. or Feb. I originally wanted a S&W. Then a Colt. Kimber. Sig. With my expected tax return and money in savings I would have no prob picking up a $1K gun, but lately I find myself leaning toward the GI SA 1911 for the quality and affordability. I had a Rossi .357 mag snubbie with that stupid lock thingy on it, and hated the retardedness of the whole idea. I'd definitely be changing that if I had another gun with a dumb bass lock on it.

    If memory serves me correctly, wasn't this an anti-gun group's wish for all pistols many years ago? Also, seems smith wesson kow-towed to their wishes, even though it wasn't made a law & many gun enthusiasts boy-cotted smith because of it? Anyway, I guess that all blew over because the boycott has obviously been dropped & no one mentions it. I didn't know that Springfield also did it.

    I know some imports have it because, while not required, it gains them 'points' when they are trying to get their weapons approved for import by ATF.

    Meh, my Bersa had one; i put the key in the safe to prevent unauthorized locking and had no problems with it. If i wanted to leave a handgun out but worried about kids (or my insane cats) i would consider it a plus.

    I don't use those stupid external trigger locks or breech locks, though the one from my Ruger GP100 makes a fine padlock for my footlocker (no scuff coating).

    i think all new springfields have them. best thing is to get rid if the ils all together. things like that have a tendency to break when you really need it. not a good thing on any gun much less a sd gun.

    and if anyone has a good way of getting rid of the bersa lock i would love to know

    Yes, as far as I know yes all of the new production model SA's have this...
    I guess that the good thing about it is that it is easily removed. The change to mine took like 10 minutes to do.
