Glock 43 sights fit larger models?

[Scribbly1]

Title says it all, had some TFX sights put on my 43 and not super thrilled about shortening the sight radius that much and I am used to a higher viz front sight like the HDs offer,so I thought about changing them out. But I have my ole trusty Glock 23.3 that gets nightstand duty every night that has been in need of a sight upgrade for a while so I thought of killing 2 birds with one stone. If I take the TFX off the Glock 43, even though they are smaller will they fit and work on the 23?

Thanks in advance

Nope. 42 and 43 interchange but not on anything else.

Rear sights, although more narrow seem to be the exact same height?!?

I read that the front sights are the same and that 43 rear sights would work on 23 but not the other way. I don't remember where I read it and I haven't tried it.

The front sight on all Glocks are the same. The difference is in the rear sights. The 42/43 rear sight is 6.1 mm high were as the standard height on the glock 23 is 6.5 mm high. Glock sells a 6.1 mm high rear sight part number nr17g25 that fits the glock23. This is the standard height rear sight for the Glock 17 long slide. You would have to adjust your hold as needed. If the TFX sights measure according to this they will work. I have run truglo tfo on all my guns but the last three Glocks I bought I put Glock factory night sights on. The set costs $57.00 and I install. I feel they glow as well as any for half the price.

The 23 sights will work on the 43 but they will hang over each side of the slide.

Thanks for the feed back I think I am going to give them a try on the 23, and put something on the 43 to get my sight radius back

Well two ranges visits down and the sights are so close to factory that I can't tell ANY difference in accuracy
