Doesn't that leg of the spring simply act to keep the grip safety engaged (pushed out)? The leg on the grip safety is actually what locks the sear, right?
Yes, the sear spring only keeps the grip safety pushed out. However, if it doesn't push out "far enough", the grip safety is "always" deactivated.
OP, if there is free play between where the sear spring starts to push on the grip safety, and the hard stops between the grip safety and the MSH, then you need to play with the spring a little to push the grip safety out further.
If there is no play, meaning the sear spring is pushing the grip safety out as far as the MSH allows, then you've got a disabled grip safety.
There's debate on whether you need this thing. IIRC, JMB's "original" design only had a grip safety; no thumb safety. In the Kimber Series II guns, there's a firing pin safety that is tied to the grip safety... some would say that as long as that safety works, that's all you'd need, even if the "original" grip safety is disabled.
Personally, I'd make sure that it works, replacing the part if necessary.
Actually JMB was forced to put the grip safety on at the behest of the army not the thumb safety. Some of his earlier designs actually didn't have a thumb safety, either.
In a Kimber, the grip safety not only blocks the trigger, it disengages the firing pin stop. Who ever modified it hopefully knew what they were doing. Have you fired it yet ? If not, you can do a quick check by putting a pencil down the bbl, eraser end first and dry firing. It should shoot the pencil up (pointing the pistol up, of course.
Khunhausen's book is a must have if you care about 1911s at all.
The IDPA rule gives me one more reason that I won't play with those guys. It's like they invented the rules to trip up shooters so they can feel superior. I'm surprised they don't tell you which side of your mouth your tounge must hang out when making a difficult shot.
I think the whole legal aspect is over blown as far as a defensive shooting goes. It's in the same boat as using reloads. I personally don't and I'd rather have a more stock gun when standing in front of a jury, if it came to that (marginal circumstances around the shooting). I think for the most part, at least in my state, it's either a good shoot or not. I've always had mixed feelings about this sort of topic. You could go so far as to not use hollow points because you don't want the PA to accuse you of being out to kill somebody with your evil man killer bullets.
I think the legal issue would be, IF you sold it to a person and IF that person were to shoot themselves or another and IF it was shown the grip safety was at fault (not to mention failing at the 4 rules of firearms handling ...but we know how juries are) and IF it was proven in court that you knew about the safety issue and or actually deactivated it THEN MAYBE you could be held liable in some fasion.
I would think the person who sold you the gun should have told you the GS was deactivated in the interest of the above paragraph. If you decided to sell it, I'd recomend disclosing the info.
