You have a LNIB Gen 4 G19 listed here for $475.
There is a NIB G45 listed here for $500.
There is a LNIB G19X listed here for $525.
All listed at reasonable prices.
Distance may be an issue. I'm also looking for a Glock 19X but the one I'm seeing posted is in Madisonville, which is a long way from West Monroe, and I haven't gotten a response yet on meeting half way.
