Hello, new to this site. Hoping you guys can help me out. So I carry Federal HST in my Glock 26. I'm sure just like everyone else I'm having trouble finding ammo. I was able to find some Winchester Silvertip HPs online so I ordered them. My question is if I carry those in my gun, is it a bad idea to carry the Federal in my backup mag? The HSTs are 115 grain and the Winchesters are 147 grain.
