Grip Safety Fitting Question

I am in the process of fitting an STI beavertail grip safety to an LSA/STI Premier Frame. The notch in the arm on the grip safety appears to not be cut high enough to allow the trigger bow to move past it when the safety is pressed in. It appears that I need to remove about a 1/16" of material. This seems like a fair amount based on tolerances so far and, since I can't put it back, I just wanted a sanity check. Is this a reasonable adjustment to be made? Thanks.
 
Make sure that the Grip Safety (GS) is rotating all of the way up. I had the same problem you described and was about to knock off the bottom edge of the GS tang before I realized that the end of the tang was contacting a ridge in the frame and not allowing complete movement.
Also check the prongs on the GS near the Main Spring Housing. I had a GS wherein these were extra thick and prevented it from rotating up and letting the trigger release.

Otherwise, go gently with the file and then double check for function.
 
It is called "cut and try, cut and try", which is why gunsmiths charge an arm and two legs to do that kind of work. (Hint: when trying you don't need to install the mainspring housing or the thumb safety, just stick the pin through to hold the grip safety.)

Dave Sample's Online 1911 Class:" RULE ONE: Metal is very easy to Remove and Very Hard to put back." Ditto what Jim said. RULE TWO: " Your blue Pen is your Best Friend." That is all the rules we have.......................
 
Oh yeah! Black magic markers are the best thing since sliced bread! :)

They definitely can keep you from going overboard.
 
When I took Daves on line class, fitting the grip safety was one of the higher time consuming task. I used the blue marker more than maybe I should have but I'll be darn if the grip safety didn't turn out pretty nice.
