Geco I never knew existed until I got a gun broker account. It seems cheap if you can find a day nobody is bidding aggressively on it. Most my guns aren't super picky unless I try to run the USA Forged ammo harvested from the cargo hold of the Titanic. I don't count the SR22 as it's still breaking in and prefers CCI and Agula over the other ammo.
My SD ammo differs between guns. Most my 9's except the G2 and my .45 run +P critical duty. G2 was V crown since it feeds the most reliably but gonna switch back to HST.
