Thanks for the site info. I'll be using the caliper - the one I need is tiny. If no luck, I may fill the holes in the frame somehow and replace the grips. They seem to be available in Poland last time I looked. Doing that, I'd be afraid to ever sell it for fear of getting sued by someone careless. I wonder how many friendly troops were shot by these pistols w/o safeties, or the French MAS bolt action pre wwII rifles.
