Glock 42/43/43X/48 – TFO Sight Set – Low Profile


PLEASE DOUBLE CHECK DETAILS, MODEL FITMENT, MOS COMPATIBILITY, COLOR OPTION, AND INSTALLATION REQUIREMENTS BEFORE PURCHASE.

TRUGLO’s TFO low-profile sight set gives Glock slimline pistols a bright, durable iron sight upgrade that stays visible across lighting conditions by combining fiber-optic visibility with tritium illumination. This parent card keeps the fitment family tight while letting the buyer choose the sight color arrangement that fits their preference.

Available options are organized under the product variants. Both verified variants fit the same Glock 42/43/43X/48 non-MOS family and use the same TFO low-profile platform, so this is the right kind of combine — clean, searchable, and not sloppy.


Variants / Options

  • Green Front / Green Rear — TG131GT1A
  • Green Front / Yellow Rear — TG131GT1B

Fitment

  • Fits Glock 42.
  • Fits Glock 43.
  • Fits Glock 43X.
  • Fits Glock 48.
  • Designed for the slimline / single-stack Glock sight family listed above.

Does NOT Fit

  • Does not fit Glock 43X MOS.
  • Does not fit Glock 48 MOS.
  • Does not fit MOS optic-height setups unless your exact sight-height and optic configuration are verified separately.
  • Does not fit standard double-stack Glock models such as G17, G19, G19X, G26, G34, G45, or G47.
  • Does not fit large-frame Glock models such as G20, G21, G29, G30, G40, or G41.
  • Not a suppressor-height or optic co-witness sight set.

What It Does

This sight set gives slimline Glock pistols a brighter sight picture across lighting conditions without batteries. Both variants use the same TFO tritium/fiber-optic system and low-profile fixed sight setup; the main difference is whether the rear sight uses green or yellow fiber color.

Why It’s Worth It

This is exactly the kind of product that should be variant-combined. Same line, same fitment, same use, same low-profile sight lane — just color preference. Clean store structure wins here, and nobody has to dig through duplicate product cards like they’re searching for lost treasure in a sock drawer.
