Which is the better self defense round? I was about to stock up today at a local store and could not remember which I usually shoot. Actually, I am not sure if I knew they made 2 different sizes. What do you prefer? Why?

I've heard they recommend the 124. Higher velocity. I picked up a box of 147s. I use a suppressor.

The 124 +p and 147 grain are on the FBI "approved" ammo list. The standard 124 gr. is not. I still think any of them are great rounds.

Not sure why it's not as testing posted on M4C showed comparable expansion and slightly more penetration compared to the +P version.

The 124 gr +P kick a little harder and make a louder bang.  The 147 gr. feel nice.

I prefer any modern loading in 147. Older 147 ammo gave the load a bad name as many older 147 gr projectiles did not expand. Newer 147 is not a problem and I  carry it when carrying a 9mm ( Ranger T 147gr or HST 147gr).

If you can't remember which round, always get the heavier one.

The 124 GD seem to expand better

Unscientific, but if they're both on the FBI list, I tend to go for the heavier bullet weight. Just a personal preference, I find that heavier loads tend to be easier for me to shoot well for some reason. 180gr in .40, 147 in 9mm, 230gr in .45...

 According to Speer's chart, they ALL underpenetrate except for the 147g in bare gelatin:

I was a Gold Dot fan until I really compared all the data.  I have a spreadsheet in the Ammo FAQ (about 1/2 way down, zoom your browser to about 200% to make it readable): Best Choices Defensive Ammo

Another thing I got from my chart, and mentioned above, heavier is almost always better.

There are several 124gr standard pressure rounds included on ARFcom's list.

I stocked up on HST's for everything.  It really seems to be head and shoulders above the rest.
147g for 9mm
180g for .40
230g +P for .45

More of a generic statement than a what and why answer.

I can only speak for my company that formed in 1997.

In Gold Dot 9mm the 124+P sells better than the 147 and the standard 124.

Conversely with the HST and the Ranger products the 147 blows the others out of the water in sales.

All I have is 124gr+p GD's.   It's what shoots best out of a full size Glock & Beretta.

I carry .40 anyway, so 9mm is not used much.

It's been a while but I performed my own test with several different loads including silvertips, winchester 147 and the golddots.  I do not remember what grain the gold dots were at that time (almost 15 years ago) but I used several different mediums.  Boxes of river mud, wet phone books and the actual river bank itself.  the gold dots outperformed all the defense loads I tested in penetration, expansion, bullet retention and wound cavity. I think it was the 124 grain gold dot...don't know if the 147 gold dot was available then.   But I remember that it made a markedly larger hold and cavity in the river bank and boxed mud tests and had deeper penetration as well.  The silvertips underperformed for penetration so I used the rest of what I had for range ammo.    That's my two cents based solely on my own redneck testing.  YMMV but I carry the gold dots and have no lack of confidence in them.    might have to do a test on the 14 vs the 124 now.  

Edit for accuracy.  I now carry a .40 and the 9mm is relegated to the safe however I still carry the gold dots.  When I tested the 9 I also tested 357 since that was the load my girlfriend carried.

While I'm sure the 147gr works fine, as a reloader I was never comfortable with putting such a heavy bullet given the 9mm's small case capacity.

The 124gr just seems to be a better balance of bullet weight vs/ room for powder.

It may simply not have been tested. I try to keep my chart synced with Doc Roberts' listing, so I may have overlooked it too - is it on his recommended list?



 




On a recent update, the standard pressure 124gr Gold Dot was added to the list.
I checked the list here on AR15 too, it shows both the standard 124 and +P 124 gr Gold Dots now.

I carry the 147 because A) I prefer heavier rounds in a given caliber, and B) it is on our authorized ammo list.

I am not sure that there's a nickle's worth of difference between either load.

It just felt like loading a 250gr bullet into a .38 special case. It just goes into the case too far for my liking. I know it works, but I don't feel like being objective.

Per the 2 ATK engineers I spoke with at the SHOT Show last January, the +P 124 Gold Dot is their best 9mm Gold Dot product. Besting that round is the 147gr+P Federal HST. The 124 +P HST is third in their line. From the horses mouth.

When using an AR in 9mm caliber does it really matter between 124 and 147? I don't think it does.

147gr. I favor a bit more penetration to (maybe) a bit more expansion. The heavier one offers better barrier performance. And, the 147gr recoil better.

Gold Dot 124gr+P is what shoots best out of My Kahr PM-9. Unless I hit what I aim at expansion doesn't matter, nor does depth of penetration so I shoot what I'm confident in. Hell I wouldn't want to step in front of a WWB 115gr for that matter from a good shot ! ........WVleo

I agree you got to make hits .

But penetration does matter.

Would length of barrel be an issue here. The heavier rounds go slower and the it takes speed for a round to expand . At least that is what I've understood. I'm sure once you throw the +p variable in there it can equalize things

According to Dr. Roberts, in 9mm there's very little difference between 4" and 3.5" barrels.  

However, anything shorter than 3.5" is a different deal.

From what I have read over the years, I doubt you could go wrong with either one.

The difference in the two is pretty much splitting hairs.

My CHL load is the 124 +P GDHP.
