being the prudent one in my family, I did a bit of cost analysis.
Complete 9mm upper for a G19: $379 at "something" tactical, one off of Wolf Barrels
Lower parts kit from Brownell's: $49
Polymer 80: $160
$580
New Glock: $509 at Budsgunshop.
Makes a world of difference IF your hand doesn't fit the OEM grips tho. I might still build one, but mostly for the honor of having no serial number. Everyone should have one that gummint don't know about.
Oh and btw... I am also a two

owner. G19 gen2 and a G21SF gen3. Like them both. They would be my first choice bugout firearms.
