I am looking for a Para LDA with a full size grip and a 4.25" barrel. I prefer a single stack but a double would be OK. Well here is the issue, I want actually need, it in 9mm. I know go 45, I can't due to restrictions. Para does not make such an animal. So the question is..Are the frames for these all the same size. It is my understanding that the double stack frames are...this is why the mags on the 9mm are pinched in so much. As I said I prefer the feel of the single stack, so are these the same? I was thinking of getting a 7.45 lda and converting it to a "commander" size 9mm. Any advise or gunsmith recommendations? WOW that was long! Sorry.
