Helping a disabled friend,,,

[contender1]

I have a friend who is disabled & on a very limited income. He has decided to try & build a Glock 17, Gen 3, from one of those 80% frames.
He is in need of a few parts.
Used, are fine.
I already have had some help from another friend,, (Thanks RoninPa) but he's still in need of a few things.
He needs the following to complete the lower.
(1) Slide lock spring
(1) Trigger housing with ejector


And if anybody has a slide & barrel assy or at least some of the upper stuff, (except sights,,he has those,) let me know.
He has some money but not a whole lot.

Now,, I'm a totally un-educated person when it comes to Glocks & their internals. I'm a Ruger guy,, and Glocks,, well, they are not my thing. But I do want to help him. He doesn't own a computer, (thankfully, as he's a bit old school & doesn't understand them.)
But this guy has a heart as big as the Montana sky!

Any & all help even if we have to spend some money would be appreciated.

Head on over to Marine Gun Builder, both the website and his Youtube channel.. All the Polymer80 information you could possibly need is there.

Thanks! I don't do you-boob,, but I can look at a website. Plus,, I do have a few friends who are well versed in Glocks I can ask questions of.
