aridan how do you adjust the grip safety?
The easiest way IMO is to disable it completely, which is what I did at the end. You cut a piece of bike tubing about 2" wide, and slip it over the grips - presto, no more grip safety!
If you still prefer to adjust the tension required to compress the grip safety, you need to take the Main Spring Housing out. You'll see the sear spring which has 3 parts. Looking from the back of the pistol, the grip safety part of the spring is the rightmost one. You bend it GENTLY towards the front of the pistol, making sure NOT to touch the other 2 parts, the left and center one. This will make the grip safety lighter, i.e. easier to engage. However, I found that with my palms I still had a problem engaging it - I have skinny hands, and would literally have to change my grip to have the grip safety engaged. This does not happen with my STI Trojan - which fits me perfectly, and I don't need to mock around with the safeties of any kind.
Another option would be to replace the grip safety with something 'meatier', thus helping you to engage it every time. This part looks like a standard 1911 part so it should be easy to get a Wilson Combat grip safety & then say 'Hey, I have a Wilson Combat in .22'!
If you never disassembled a 1911 you should view a video on youtube to help.
HTH.
P.S. I'm still planning to disable the Firing Pin safety, to lighten the trigger pull for my wife's sake.
