Unwrapped a brand new Glock 20SF this am. Wife also included some Hornady 155gr but need to know what I should be purchasing. I have been told Doubletap but also it seems the UW stuff is smoking hot so gimme your suggestion. I will be adding some nice mods here soon as well! Can't wait. This is going to be a fun weapon! Anyhow, looking forward to this bad boy! Merry Christmas to all!
