Removing the Internal safety on the Springfield

[The Dutchman]

I have heard that the Internal Locking System on the Springfield 1911's causes more problems than they solve, how do you remove it to bring it back to a series 70 which is what Mr. Browning intended for the gun to be? Thanks

P.S Is it true that it effects the trigger crispness of the design?

Just replace the mainspring housing need std series 70 guts .. the guts in the ils housing are different..

No it doesnt effect the crispness of trigger only reason i replaced mine was i wanted magwells and my 2 loaded models didnt have them

springfield 1911s have a lock on them???!!!


well, that settles it, when i buy my 1911, it will be a Thompson Auto-Ordnance.

yes they have them in the mainspring housing so as i said above its easyly removed if you wish to remove it

No need to change MS housing, unless you want too for reasons other than just removing the ILS. The standard parts needed will set you back less than $5, a little more if you want to go with a reduced power Wolff MS.

I replaced the following on my TRP:
MS housing cap
MS Housing cap retaining pin (Note: not used on ILS MS housing)
MS (stock 1911 is 23#; I went 20#) The ILS MS is 28# and I noticed a major trigger improvement by removing 8# of MS pressure.

Easy fix and less than 5 minutes work.

Hey, Dutchman,

Series 70 does not mean "original design" or "without firing pin safety or key lock." It is a Colt trademark for the Government Model mutated with a collet type barrel bushing without Mr Browning's knowledge or input (since he had died 44 years before that model came out.)

I don't like superfluous action parts like firing pin blocks or key locks but anybody who wants a real JMB/Colt 1911 with hand-biting hammer/grip safety and teeny sights is welcome to it.

I removed the ILS from my Springer GI. Didn't make as much of a difference in trigger pull as when I replaced the ILS in my 9mm 1911. It's an easy job. I got my parts from CDNN investments. They were Colt parts. Takes you less than 10 minutes.

I take that so call hand biteing JMB/Colt any day over a Springfield or a Kimber.I have a box stock Combat Commander on my hip at present. I wish I had a couple of doz more.

The Old Fuff will be second in line ...

It never caused me any problems, but I also removed the ILS from my pistol. It's very easy to do. (I'm no more than a tinkerer) I think other manufacturers engineering locks into their firearms should take note. Don't let Springfield's lock be a deciding factor on a purchase.

Springfield's ILS is a great way to play both sides of gun politics. It lets them put on a lock to satisfy the lawyers and antis. For us, it is 100% removable for just a few $$ worth of parts. The parts are all in the mainspring housing.

I have an older (1994) springfield, i'm not sure if the MSH originally had an ILS or not because i bought it used. I replaced the MSH on mine simply because i wanted a flat checkered one with a lanyard loop. I have zero gunsmithing ability and i did it in about 2 seconds with the help of my girlfriend (laugh if you want, you know its hard to get everything held in place and lined up and then drop in a pin with all that spring tension.) , I got everything lined up and in place and told her to drop the pins in. If you want a new MSH i recommend Smith & Alexander. That will set you back about $40-$60 but as mentioned above you don't need to get a new one.
