I have a 70 series govenment model and I want to swap the hammer and trigger and I was wondering how much work is involved it really doesn't look like that much to take them out but I am wondering how much "fitting" is involved,
thanks, and does anyone reccomend a hammer and trigger to make the job as easy as possible?
oh yeah I don't want to cut up the gun I would rather just cut the parts so if I ever want to put it back as original thats a option.

What you really want is a prepped hammer/sear set. The trigger really has little effect as far as trigger pull and crispness is concerned. If you don't already have one, a book on gunsmithing for the 1911 .45 will come in real handy when you start working on your pistol. Here's a site for the Hammer/Sear Set.

Changing out all the trigger parts is simple as pie.

I agree with the others, get a prepped 'drop in' set.

After changing these parts you MUST perform all the safety checks. There is a grip safety test, thumb safety test and a disconnector test that must be performed. Look these up in  a book, its too lengthy to post them all here.

I'd go with the C&S drop in set as well. Quality stuff.
