9mm 124g or 147g

Which weight do you think would run better in my Glock 34 with a standard barrel?

 

[ASP785]

I run 124s mainly because they are cheaper and I shoot a lot. I doubt you'd notice a difference with either.

 

[gun4hire]

They are the same price where I buy them or I would shoot the cheaper of the two also.

124's will give you better velocity from a pistol barrel and should shoot close to point of aim. 147's are usually fired out or 9mm carbines and buzz guns, or used as subsonic in handguns.

arent most guns designed around a 124gr bullet? I think I read that somewhere but am not 100%. Far as your question. You can get a better range of velocity from 124's. You can slow them down or speed them up, got to watch 147's a little more approaching max load of fast powder. just my .02

Thanks for the responses. A little food for thought

I've tried and tried 147 in factory and Lone Wolf barrel - couldn't find the accuracy with different loads, read somewhere something about wrong twist etc.
124s shoot much better in both barrels.

Little gun tech: The longer and slower the bullet, the faster twist needed in the barrel to stabilize the bullet.
The 9mm luger cartridge was designed over 100 years ago for the 124gr bullet, and any 9mm pistol will shoot them.

Some use heavier bullets loaded slow to make minor power in competition and you just have to try the specific bullet in your gun to see how it works.
However, the 147gr loaded minor in a G34 has been done successfully more than once.

If you're looking at competition 147 is nice, as there's less recoil and still keeps the power factor up.

Aside from that, 124.

I think I will buy some of both and see which I like better
