It's the exact same bullet and I know of no other 9mm load (BPLE) that has such a stellar record for putting down bad guys right now, although I hear that the Speer 124 gr. +p is getting closer.

Here's how "bad" the "antiquated" BPLE fares in a modern FBI 4 layer denim/ calibrated ballistic gel test:


10% Ballistic Gelatin Tests for:
Federal 9mm 115gr. +p+ 9BPLE

Testing Platform:
Glock 19

Barrier:
4 Layers of Denim

Penetration: 12.50"
Recovered Weight: 110.1 gr.

Velocity: 1298 fps.
Notes: .680 at widest “leg,” .551 cal average diameter.

StoppingPower.net Forums - Federal 9mm 115gr. +p+ 9BPLE - 10/05/2004

So what if one were to load the 125 Gold Dot designed for a 357 Sig, into a 9mm case.... what velocity would be required to get reliable expansion ???

125 gr. I don't know nor care, but for one gr. less there is this:

9mm Luger +P+ 124 Grain Gold Dot Jacket Hollow Point Box of 50


Yes, I have shot it and it's hot. Approx. 80 fps faster than a standard Speer 124 gr. +p in a G19. Extremely accurate as well. New Starline brass and real Gold Dot bullets.

The reason I ask is that 124 GD are often sold out at the various places I buy components but they will have the 125gr version and I have this bright idea that 1 gr doesn't make much difference but on the other hand I know there must be a difference. When I compare the two, I immediately noticed the cavity in the 124gr is much deeper.

So, I still wonder if it might be doable but I wonder what minimum velocity is needed to get expansion in the 9mm comparable to the 124gr. I suppose I could try drilling the HP a little deeper

I don't hate glocks. I don't particularly like them, but I don't hate them. I own one, a 20, and that one only because S&W refuses to make an M&P10.

What I do dislike is when the fanboys come on another brand forum and spout their constant "yours is **** go buy a glock" BS. Do I go to glock talk and say glocks are **** just buy and M&P? NO.

I'm a big Beretta 92 fan and belong to a forum that caters to Beretta enthusiasts. A member there is a competitive shooter with the 92-series and has even been on Season 1 of Top Shot as an instructor on the 92 for the competitors. He is also a sheriff's deputy where he lives, and he gave a report of the time when he qualified with his weapon...

He said the instructors were rude and snotty towards him because he didn't carry a Glock like they did, making disparaging remarks about his choice of handgun. His shooting skills shut them up for a little while, but they continued with the "Get a Glock" mentality the entire time he was on the range.

I like Glocks even though I don't currently own one. The G21 and 17 were nice guns, though a bit clunky.

Youtube post by TNO9 with a glock 19 4" has done a lot of 9mm test and some data goes like this.........(4G) ..levi/gel.

Federal 115 +P+ 1236fps 13" penetration, bullet .578 dia
Speer 124 +P 1210fps 13" penetration, bullet .615 dia
Federal 147HST+P 1050fps 11" pen......... bullet .70 dia
Federal 147 HST std 1008fps 13" penetration Bullet .66 dia

They all look like winners to me.............
where the bullet ends up on the target per point of aim would be what I would look at if recoil was not an issue and your gun can shoot these loads.

Note:
the USA Armed forces replaced the 1911 in 1985 for the Beretta 92........so it can't be that bad and I like its looks, feel and balance. It and the Glock are proven war veterans that keep on ticking.......
