Slide to Frame interchangeability?

I have the opportunity to purchase a G38 (prior G37 owner)and am wondering if G19 and G23 slides (have good deal on these too) will fit and function on the G38 frame. Of course I would use caliber correct mags. Right now, in my neck of the woods, 9mm and 40S&W is easier to come by than 45 GAP.

Wow, it has been quite a while simce my last post. Too many others have asked and answered questions I have had.

Regards,

RUBEC

I’ve ran my G31 slide on my G37 frame, I’ve ran a LWD 40 to 9mm barrel in my G31 slide on my G37 frame, I’ve also ran my G37 slide/barrel on my G31 frame, both are Gen 3, so I’m able to shoot 9mm, 357 Sig, 40 S&W, and 45 Gap on either frame with the correct slide/barrel/mag combination with no internals changed in either the slide or the frame.

I also shoot cast bullets in every caliber except 357 Sig, doesn’t matter the combo, everything fires and function as it should.

You need to provide information about the slide generation and the frame generation.

Why did you resurrect an old thread?

Yes you can as Gen 4 slides work on a G45 frame so it will also work on a Gen 5 G19.
Be sure to install the plate cover as the one used in the Gen 5 so it clears the frame.
The ambi slide stop may or may not work as-is, I ordered a spare OEM and cut off the right hand side and used that.

As far as I'm aware, there is some differences in geometry with the trigger bar in the Gen 5 the way that it interfaces with the firing pin block, but from what I've done with my G45 (G23 Gen 4 upper) I have not had any reliability issues but I have also only used it to jackass around at the range, and not for any legitimate carry purposes.
