Nearing completion of my homemade .22 conversion I need to cut the extractor slot in the slide. I did purchase the Nelson extractor and spring (3 sets) But it's quite wide. Being the Nelson slide is squarish in the rear about .980" wide the Nelson extractor is flush at the rear. I did trim the width of my tool steel slide to .920"(put slide on surface grinder and removed equal amount on each side, same width as the Nelson scope rail). If needed I can remove .030" for rear of the Nelson extractor. However I'm wanting to find something smaller so I can cut a radius on the top part so as to lower weight.
 Does anyone have dimensions of other extractors like something on a 208, maybe a 41 or other .22 pistol?

Volquartsen M-41. Took some fiddling around on the microscope. Reticle alignment is frozen, and it's got dumb old micrometers. The 20x eyepiece doesn't help either. But it was a great deal.

My tool makers microscopes have micrometers too. I up graded to Optical Comparators.
 Does the M-41 have a pivot pin hole? I see it's quite a bit smaller than the Nelson extractor, it's 1.25" long, .36" wide  at the pivot pin hole and .32 at the rim hook.

Thanks, I think it will work! Will call them Monday! I assume it will fit flush with outside of slide. Doing the math the difference between the .45acp and .22 case is about .085"/side. I then can use 3/8" radius cutter on my .22 conversion slide. I did purchase a used 3/8" radius cutter on ebay so I can shorten the length without modifying the cutter I have. Maybe they have the pin and spring too.
