Colt hammer spring. safe?

skychaser53
Last night on my series 70 Govt model I replaced the factory(23?) hammer spring with an 18 lb spring. It lowered my trigger pull 1 lb to a trigger pull of 3lb 10 ounces.! great ! . Now , is is safe? Is there any way to test it? bump it against my palm ? I'm not going to drop it on the floor lol..
Can I, or should I, put number 7 polishing compound on the contact surfaces. use snap caps and dry fire it 6 times to smooth out the surfaces. clean surfaces completely.. The Ar 15 minute trigger job(which I haven't done yet ) made me think of this..
question 3. what is my 70 Gold Cup hammer spring weight, is it 23 lb? I've got it in the shop having the ambi safety replaced. I think, if I remember right, the GC trigger pull is about 3 lbs 8 ounces.

    a Legal Hard-Ball gun is 4 pounds and legal NRA bulls-eye pistol is 3&1/2 pounds but that does not determine if either is SAFE but rather the angle of the surfaces of hammer hooks and sear nose as well as the length of the hammer hook . If you take an unloaded pistol and with the slide back and no magazine in pistol then trip the slide stop and the hammer drops then the pistol is unsafe even if the trigger pull is 8 pounds. I would take to the range with either 2 rounds loaded at a time or better yet a older magazine with the slide stop part of the magazine follower bent down and if the hammer ever followers the slide closed then rethink your trigger job.

    I'll try your suggestions to make sure it's safe.. Safety is my First concern. I just ordered some different springs 19,20,21, in case I need a heavier spring. Changing the hammer spring myself was a nice learning expirence, but I don't want to get carried away lol.
    I have a Casul Gold Cup trigger that I was thinking about putting in The 70 Govt model.to set overtravel.. I watched a video on it and it doesn't seem to hard. Is this something I should do?
    Thanks for your help previously in telling me how to set O.T. on my Gold Cup..

    edit. For guys that want to see how Colt insides works , I recommend the pages this link will give you.

    after reading the link I just gave, I am glad I did not attempt to change the ambi-safety myself, it needs filed and fitted.

    Not all primers have the same amount of impact sensitivity. IMHO by changing the main/hammer spring you would have more potential problems with reliable ignition of the primers, then safety. It seems various factors affect primer sensitivity, i.e. Manufacturer, Age, Storage, Type of Ignition etc.

    Recently because of the difficulty of obtaining primers at descent prices, I utilized some old (1990's?) Winchester primers that I got years ago. I had so many misfires that I became discussed, broke down the entire bunch, ( 500 ), and reprimed them with Federal primers.
