Thanks for the input! Just so happens I saw you comment after I made the material removal modification last night and came back to the forum to share what I did. That being said, I had been trying to modify my grip to ride the left side safety but my fingers are on the shorter side and my thumb only partially rode the safety. Consequently, when I shot, my thumb slipped off of the top of the safety and my grip is compromised. So I shoot with my thumb under the safety on the left side. That said, it was actually my trigger finder bumping the right side safety upwards in recoil that was activating the safety. Before going further, I think it's important for me to point out that my safety had quite a bit of free play in it before I installed the DS Perman spring and modified the safety. The safety would move up slightly and the gun would be rendered safe. Mind you that the entire red dot indicator (and then some) was still visible so clearly the safety was. It meant to work this way.
As for what I did... I actually did two things. 1) Installed a DS Perman spring and 2) Ground off about 1.5 mm of metal on the safety as discussed above.
Before doing the modification I removed the slide and I could see exactly what the problem was. (Please excuse the terminology that I use in the following section; I don't know all the proper names of the parts). The nub (for lack of a better word) on the inner rod section of the safety was already extremely close to going under the sear. I would estimate that there was only about 0.5mm to 1mm of distance between them.
So I removed the safety and the ejector/seat cage. With those parts removed, I replaced the safety detent plunger and safety detent plunger spring. I installed the DS Perman spring (which was slightly tricky given the increased pressure it produced). I then put a narrow diameter stone grinding wheel on my Dremel and very slowly removed some material. I'd say that I may have removed 1.5mm of material (before removing the material, I saw that when the safety level was fully engaged, there was about 3mm+ of metal on the safety nub that pivoted under the sear to render the gun safe). Then I reinstalled everything and it works great! It took me a while to reassemble everything as a lot of pieces have to go in "just right". The gun now has a safety with a very positive action and I don't think I will have the accidental, trigger finger, recoil-induced, inadvertent, safety activation anymore. I'd point out there is still some very very minor play in the safety, but it seems necessary given the gun is a mechanical instrument. I would venture to guess that the DS Perman spring alone may not have solved my problem. Only in combination with the removal of material in the safety lever do I think the problem would be been resolved.
Apologies for the long post but I was so thankful for all of the help I got from this forum that I wanted to post the details to help anyone else who might be experiencing the same problem that I was. If anyone is interested in getting more details on exactly what I had to do to get everything to work/go back together, please reply here and let me know.
