Is there any height difference in the 43/48 vs the 17/19?  It reason they would not work?

I know the 17/19 sights are wider and are a potential fitment issue in the 43.

But would 43 sights still work on the full size guns?  They're just a few mm narrower right?

I have a spare set of night sights I'm not using but they are for the 43/48.

TIA

I put a 43x/48 on one of my fullsize slides since it came in the height that I needed. Nothing bad other than it is short side to side.

Go ahead and put those bad boys in and tell us the answers.  Please try 'em.  Hopefully they work.  The more options for sights the better.

My 43/48 XS sights went on without a hiccup onto ny G45.

Instantly, the rest sight is the exact width of the flat contour of the rear sight grove.

I'll get pics when I get home.  Honestly it made centering the rest sight easy because of the matching width.  And no big gaps on the side, looks like any other normal sight.

I have Glock 17 sights on my Glock 21. They are just narrower is all.
