factory ammo?

[thester]

Whats a good factory ammo for deer with a factory out of the box Glock 20 gen 4?

Underwood has plenty to choose from!  Speer and Federal have some good offerings with Gold Dot and HST  JHP's.

Evening,
Underwood's 180, or 200gr XTP has served me well for whitetail.
I would like to try their 150 Grain Xtreme Hunter as well
Thanks

Ken

Kinda like RoJo said.... you have many choices.  Deer are not tough to kill.  All the suggested loads will work.  If you are more sensitive to recoil
might consider the Hornady 155gr XLT's and the Hornady 180gr XLT's. 

You have lots of good choices.  Pick what suits you.

Underwood 180 or 200gr XTP should be good.

I found that in order to get them to cycle in my Glock 40 I had to get a heavier spring (Glockmeister is what I used but I've heard good things about several companies)

The Hornady loading of the 180-200gr XTP is lighter and may cycle more reliably if you have a factory spring (and it will still do fine).

Also Federal Trophy Bonded is good as others have mentioned.
