On a production gun, can a new hammer and grip safety be dropped right in or do these parts usually have some fitting/adjustment required?

It's easy. Look on brownells or youtube

They make "drop in" beaver tails and they generally look like complete shit. The lines don't match. They still need fitting to the trigger bar for at rest blocking and when depressed allowing trigger to move rearward.

Drop in hammer kits usually come with the sear and disconnector already fitted to one another. However you'll still need to fit your thumb safety to make sure it properly engages the sear.

Hammer is not difficult.

Grip or thumb saftey. .. takes finesse.

I have gotten away with using OEM Colt "rat tail" grip safeties several times so far, that came from horse trading and a gunsmith's box of leftover and take-off parts.

The only difficulty with swapping hammers is you go from a series 70 to a series 80, the 70 has another notch, basically a half cock.  Other than that they are plug and play.



The grip safety replacement has more options, if you go for a drop in, then other than a small amount of fitting and it's an easy replacement.  If you decide to go with something more custom then fitting is involved, you have to alter the frame to have it line up the way it should.  



This is a series 70 GCNM that I fit an Ed Brown safety.

Never never expect any part on a 1911 to drop in and work perfectly. You might get lucky, or end up spending hours with files or stones to get it right

Without a new sear a 1911 hammer swap is a crap shoot.

It's been my experience that if everything just drops in you did it wrong.



It probably took me 1 1/2-2 hours to fit my grip safety (still havent blended it in) and then another 1-1 1/2 hour fitting it* to the MSH because it was too tall and was holding the grip safety down. Then I swapped that out out with a different mainspring housing and I just had to hit a couple high spots with a file so it would fit right.

*that time isn't including smoke breaks when I was about ready to fling it in the trash, say fuck it and buy a Glock.

I really like that all of your guns have identical controls.  All of my ARs are set up identically - same grip and stock and controls (except the pistol, obviously).  I know what I like and no matter which one I pic up it's familiar.

It really does make sense.




This all started with my Kimber (having a memory bump grip safety) and me experiencing an occassional failure to fire because of my grip, something I never had with original pattern grip safeties.




The thumb safeties all went to the same pattern single-side WWI style to match my New Agent, since I was already comfortable with it (which started in boot camp with my first exposure to actual USGI 1911A1's)  and the ambi on the Kimber kept getting brushed to "off" when carried, and that was  in the same IWB holster in which my New Agent never had that issue.

Thanks for all the answers guys. I was asking because I was thinking about buying a Springfield mil spec and swapping the grip safety and hammer. I ended up getting a Range Officer, so I probably won't be changing any of those parts.


If I add an STI mainspring housing magwell, whats the likelihood that fitting will be required between it and the grip safety?

Unlikely. Usually all a mainspring housing might need is a little filing/stoning of the sides if it's tight.

Concur: I have put Guncrafters' MSH in four of my 1911s and a VZ OACP aluminum MSH in my New Agent. NONE has had any issues with fit.
