Polymer80 G17 frame with G19 slide?

Discussion in 'Gunsmithing' started by whitelotus9, Aug 13, 2020.

  1. I'm looking to build a second Polymer80 frame only in their Glock 17 size this time (the first was a Glock 19). I would like to build this one as a Glock 19X. Can the Polymer80 frame be modified to shorten it to the right size for the Glock 19 slide? Thank you in advance!

    Olga17 C19 sounds like G19 Supporter

    I wish I could answer this with certainty.
    Cannot answer until next week, a relative is dropping one off on Tuesday. (G19)

    There is this ,it's not manufactured by Polymer 80 though and I've never laid eyes on one. hope this helps you.

    I hear tell the Glock Store has their serial numbered 19 X style frame for sale beginning of this week, it is not a 80 %.

    GST-9 Pistol Frame

    This is what they say of their product

    What makes the GST-9 so special?
    • Modular frame gives you a 19, 19X, 19L, & 17 size weapon system in a single 4-in-1 platform
    • Compatible with Glock 3rd generation parts, holsters, & aftermarket accessories. GST-9 is the first and only 80% lower that is compatible with Glock holsters
    • Ergonomic features include a single undercut, high beavertail, glove bevel, scalloped mag release, no finger grooves, & gas pedals as standard
    • Premium internal rail components extended 3X, made of stainless steel, & Nickel-Boron coated
    • Easily ships to your door & completes in minutes

    This is what Marine Gun Builder has to say of it.

    Basically, it's a G19 frame with an optional G17 stock extension (shown below).
