I am looking for a hammer to use on both colt 9mm upper and 556 upper with .170 pin.
Does anyone have a recommendation?

When I was in your situation I decided to sell the old large pin gun and purchase a new small pin gun.

DPMS makes a .170 rounded hammer, I believe that will be compatible with 9mm and 5.56 uppers...

Not an option. Factory sbr lower.

Thanks. I figured an aftermarket solution existed.

What's the difference between the hammer that will work with both 9mm and 5.56mm and a standard hammer? I just picked up a new Colt .170 set from the EE consisting of hammer, trigger, disconnector and 2 pins for $20 delivered. I think I have three Colts with the larger pins and figured it would be good to have a spare set.

For 9mm you want a 9mm hammer or a non-notched type hammer.

I may be all wet here, but can't you just have your 9MM bolt ramped and it will work with any hammer?

I'm using a standard AR-15 lower (Spikes) with a 9MM upper (CMMG) with a ramped bolt with no problems.
