This issue is more than common among users. Some do take their dremel to it and blend a nice slant into the protruding edge. I just find myself using my index finger to manipulate the safety on and thumb to turn it off. I also place my trigger finger mid between the mag and bolt release and it clears. These two adjustments solve the issue for me.Play with it and when the dust settles, if you'd prefer break out the dremel.
I must have small hands cause its fine with me... my only problem is once I use my thumb to switch it to fire..my thumb cant switch it back...so then i have to use my trigger finger on the other side to flip it back to safe..
I'm sorry - I am so computer illiterate it's amazing I even got on to this forum. I would have to consult my wife to post photos and she's recovering from surgery.
I just took about 1/3 of the length of the safety lever off with the dremel, then using a very sharp, cone shaped bit (that is actually made for metal) I took my time and lots of small "strokes", rounding the end off so it replicated the contour it had originally. Using a fine grit emery cloth laying flat on my bench and backed by a piece of cloth for cushioning I stroked the end until it was smooth and rounded. You really can't tell it didn't come that way.
At first when I got the safety back on the gun I thought I had taken too much off but it takes so little leverage to flip it on and off you don't need much there.
I'll wait instead of using a dremel. I'd rather have it set-up only of a right-handed as I have no need for a left-handed safety. Worst case I'll see if a friend can machine me a replacement part that has nothing on one side.
