Is 9mm NATO Mil-spec 124gr +P any harder on my G19 than say 115g WWB?

No. Your gun was designed to handle NATO spec ammo all day...

I have found this ammo is not very accurate (I have over 2k in different lots, all shoots the same - will not group reliably under 3" at 15 yards).

All the 124gr. 9mm NATO ammunition I tried has been accurate.

 

It does not have a very restrictive diet and will eat anything EXCEPT LEAD!

 

Of course, it's harder on your G19 than WWB 115-gr. It may reduce the life expectancy of your G19 to only 175,000 rounds.

 

Even if it reduced the life to only 50000 rounds and one bought the NATO spec by enough to get it at only $20 per hundred, unless my grade school arithmetic has failed me, that would be ten thousand dollars. I would gladly buy Glocks or Sigs etc. to shoot them until I can wear them out if only someone else would buy the ammunition for this.

 

If you can find the WWB value packs, they're still cheaper than that (or at least they are around here at $21.97ish per 100).

 

I was referring specifically to the Win Q4318. I've used other NATO 9mm and 5.56mm ammo with no issues whatsoever.

 

They have hit $23.99 around these parts. Plus, they are only 115 grain. If you want to practice with 124 grain, WWB is not an option.

 

As opposed to 200,000+ rounds.

 

Sure, its gonna be harder on the gun than ammo that isnt as hot.

Just like adding a super charger to your engine is gonna be harder on the engine than one making no boost.

 

Just because the gun is designed for NATO spec ammo doesn't mean it doesn't accelerate the wear by using it.

Hotter ammo is naturally harder on the gun than lighter loads.

 

I would be willing to bet that the recoil spring might need replaced more often, but I doubt the gun experiences accelerated wear. Unless you continue shooting it with a beat to hell recoil spring.

 

Yes. The NATO 9mm round actually exceeds SAAMI +P pressure standards. However, the NATO round was the round around which the G17 was designed and built so you'd have to shoot a LOT of it before excessive wear started to show up.

Shoot what you've got and don't worry about it!

 

It's been a while since I bought any - is WWB really going for more than $28 per 100 now?

 

Good point.

 

My Glocks will eat lead.

 

Yes, and that's why you hear reports of cracked frames on Berettas from army guys.
