9mm range ammo - 115gr or 124gr?

Hi all,

Need a bit of advice.

I have been running 115 gr Lawman ammo through my G19 for the few month that I've had it. No problems.

I'm going to start using the GDHP 124gt +P for HD.

Looking to place another order for range ammo. Should I spend the extra couple bucks and go with the 124gr Lawman now or do you think I'd be ok with the 115gr?

124gr shouldn't really be more than the 115gr. I typically pay around $10.95ish at sgammo for the 124gr Lawman. What prices are you seeing for the 115 and 124?

I prefer the 124 since I do use 124+P Gold Dots.

(sgammo appears to be out of both right now)

If I buy 10 boxes (which I'm looking to do) I can get 115gr for $10.99/box and 124gr for $11.40/box.

I'm thinking go with 124gr no?

I quit using 115g ammo altogether some time ago, I just stay with 124g. I feel for home/self defence 124g is a better choice so I pratice with that weight bullet as well.

Buy some FMJ to pratice with, as well as 2-3 boxes of whatever JHP you are going to use for HSD.

Try http://www.powdervalleyinc.com/ They are pretty reasonable price-wise.

Good luck.

The 115gr lawman was designed to be the practice version of the 124gr + p. Look at the muzzle velocities of the speer line and its easy to see. I practice with the 115gr, and it feels the same.

Unless you get the same velocity and bullet weight felt recoil and point of impact won't be exactly the same if you want to pick nits. Realistically I don't think it matters as long as you you getting range time with your gun. It's only an extra $4 if it will help you feel better.

You may want to just buy some of each and then decide. I will get some 115gr Lawman to compare next time I'm placing an order anyway.

Contact speer yourself. They will verify what I am saying. The 115gr fmj was designed to recoil exactly like the 124gr +p gold dot.

I have found that the point of impact to be different between 115 and 124gr practice rounds, so I go with 124gr practice rounds which match pretty well on POI as the Underwood 124gr GD +P+ that I carry.

Where do you get those prices? Do they include shipping?

I'd recommend buying practice ammo in bulk - 1000 rounds.

There is a small difference in prices between the two for some mfgs.

Well for me 115gr is to lite for 9mm. I like 124-127gr in 9mm. That said I shoot 124gr in FMJ at the range & find that my CZ'S like (shoot better) the 124gr.My P-38's also. I don't know why most 9mm ammo is in 115gr? Some times its hard to get 124gr. Love the 124gr NATO stuff.

I understand what the phone rep at Speer says, but how is it possible if they don't have the same power factor or muzzle energy?
lawman 115: pf 138600 me 368
gold dot 124gr+P: pf 151280 me 410

The lawman 115 is closer to the +P Gold dot than the lawman 124 is for sure... but it's equivalent to the 115gr Gold Dot, not the 124+P.

It's really all about the velocity. But without getting technical, just go shoot the 115gr fmj along side the 124 +p gdhp and let me know if you can tell the difference.

At what distance? Not at 7yds, that's for sure.

OK, there's a local gunshow I'll see if I can find some 115 Lawman there.

But please get technical b/c that helps me understand. If the lighter bullet load is to have the same felt recoil as the heavier bullet load, the lighter bullet load needs to have a higher velocity. The 115 Lawman is rated at a lower velocity than the 124gr+p GD.

There is no true Lawman equivalent to the 124+P Gold Dot. I find the 124 Lawman to be close enough. I will shoot the 115 stuff some time to compare.

Range ammo/best price:: SD ammo/best performance

When I shop for range ammo, the cheaper, the better. A few malfunction drills at the range are a good thing. For emergency only cost is not a factor: usually Gold Dots &/or Federal JHP.

At Self/home Defense ranges I wouldn't worry about a slight difference in velocity or energy.

I always try to match my practice ammo to my SD ammo as closely as possible.
So I'd upgrade to the 124 Lawman myself.

The Fiocchi 115 gr. 9mm is hotter than other standard 115 gr. range rounds IMO. It often can be found on sale.

I shoot my 124gr reloads at the range because I carry 124gr+P gold dots. I like my range ammo to be similar to carry ammo, minus the cost.

Nato Ball is pretty hot, and matches pretty much the 115grain +p+ that I usually carry in nines. The POI on my usual 9bple is pretty much the same as ranger 127 +p+, but off just a bit( A bad guy wouldn't notice) from 124 grain +p ??
Be safe

My agency issues the Speer Gold Dot 124 grain standard pressure round for duty. We are given the SPeer Lawman 124 grain FMJ for training purposes.

Answer to your question OP, I think you would be okay either way.

Underwood as some +p 124 grain fmj, though it is a bit more expensive.

Which ever round you can get more practice out of. If going with 115gr would give you an extra 50 rounds of ammo to train with due to cost buy the 115gr. Based on the quote you listed you could do just that.

The difference in the ammo you are using and the practicing with would be so small its not worth talking about but the thought of more "front sight, trigger press" is way more important than more recoil.
