I posted this question before in the general area, but I didn't get much
response. I have an older kit frame, in .45. I'm thinking of building
another race gun, & I was wondering if I change out the the slide &
it's components, will this frame work? One guy responded & said
he uses Para .45 mags in his .40. I used to know all this stuff,
several years back, but it's all gone now.
