Hey there! I have a Wilson combat extended thumb safety that I needed fitted for my Remington R1, and the file I have just won't do the job and I don't want to screw up the new part (if I haven't already!), so I'm looking for someone around northwest indiana that would be able to do it for me...
I have those grips on that same pistol, 'cept mine is the version with the accessory rail; the grips feel GREAT while shooting, and such a great pistol. Dead on out of the box and not a single mishap through 1000 rounds so far.
