Glock 43 lower part kit
After extensive filing of metal bumps & burrs then 2 hours of polishing they work flawlessly. Both sets needed a lot of prep. Spend the extra $20 on oem, not worth the money I paid.

Great service
Returning customer and satisfied with the fast delivery and honest on shipping orders will be a returning to make more orders. Thank you

Recoil spring
It’s advertised as compatible with pf9ss but the recoil spring is to wide to fit. Luckily I was able to trim it a little but that’s probably not part of the specs now
-
Definitely worth it.
Seems to be a great LPK. When I pulled it all out of the package I was very surprised to see it already polished up.

Excellent Fit & functionality
Went in a single stack 80 frame beautifully and functions the way it should. I would absolutely buy again. Already have 3 of these kits installed

Incredible kit (fits beautifully)
I recommended this to all my friends and family who are into building pews. Fits like a glove in either a 43 factory frame or an ss80. Pew pew responsibly

Looks simple but really not
Awesome kit. Everything that was needed was there. Due to regularitories no instructions came with the kit and that's very understandable. Eventually everything came together.
