I have Winchester Ranger T 147 gr for my 9 mm. Why? Because they have a good reputation for performance, and they aren't $3 per round. So I can afford to shoot some now & again without a payday loan.
Let's be honest though, most purpose built SD ammo will work.
The biggest issue is that it absolutely must cycle in the gun it will be carried in. Everything else is stats & opinion.

Liberals are constantly telling us about the poor and oppressed in this country. With that in mind, why do they feel the need to keep importing poor people from other countries?
