Doesn't a heavier bullet mean lower muzzle energy, and thus lower "stopping power" ?
No, the weight gives you much more momentum. "stopping power" will be fought over on this forum forever, but 1 well placed 45 is better than 1 well placed 9mm even though the 9mm is much faster usually. Just my opinion.
 
Go to youtube and search for tnoutdoors9. He does extensive testing of various defensive rounds, especially 9mm. I find his videos to be very informative.
 
I never shot short barreled ammo. In my Kahr P9, and PM9, I shoot 9mm +p, or +p+ 115gr JHP, Speer, Federal, or Doubletap and the flash and blast are very manageable, in daylight or darkness.
 
I just settled on DPX1 147 grain rounds for my subcompact XD9mm. Loving the performance.
 
*EDIT - Every time I reply to something, someone beats me to it!

I'm guessing he means Winchester's Bonded PDX1. It's a civilian available line and is set to replace the SXT line from my understanding (but that's just what i heard, nothing to back that up). It lacks the talons of the Ranger T-Series line. I'd stick with Ranger T-Series or HST in any caliber and any weight. For 9mm, I like 147 grain and understand (stated by Dr. Roberts if I remember correctly) it's the best choice for the 3.5 or 4" barrel. 124 is a fine choice as well, but 147 loses less velocity on impact where higher velocity, lighter rounds lose more on impact, part of the reason for the higher (and misunderstood) muzzle energy.
 
Which is better...... a Ford or a Chevy ? It's the same type of question. Pick the ammo you like and think will do the job. The shorter barrel will have the biggest difference at some real distance, and very little in shorter distances you'ld have in a SD situation, and it will likely not be one where you could tell the difference. Accuracy ... is more important.
 
Accuracy/shot placement is more important, but ammo is very important as well. I like my car (Mercedes) and would take it in most colors available, but chose silver because I could (my wife's Jag is white). Which one of those is better? Any edge is an edge and if it's available to you, take advantage of it.

We each have our opinion, but she chose a Jag anyway, go figure!

Ranger-T bonded and PDX1 are the same.
 
I always use the same ammo, Cor-Bon DPX for SD.

True, I have found that Speer Gold Dot 115 grain standard pressure hollowpoints work well in my Kahr CW9. The recoil is mild compared to the micro .380s like the Kel Tec P3AT and the Ruger LCP both of which I have owned at one time or another, and yet the Speer load is powerful enough to get the job done if you do your part in accurately placing them in the BG.:22a:

I don't think they're the same, I think it would be closer to Ranger SXT bonded (if there is one), not T-Series. Since Ranger T is LEO and SXT and PDX1 is civilian. Either way, go for Ranger T-Series. 50 round boxes compared to PDX1 20 round boxes for a premium. Ranger T-Series is a step above SXT and Winchester says PDX1 is similar to SXT and is it's replacement. Ranger T-Series and Ranger SXT are two different things in very similar packaging.

*EDIT - Just to clarify, I am in the "use what runs reliably and you shoot best" camp, but it's also good to know which is the best of the best out there and if the top few rounds run as good as anything else, then I'd strongly suggest picking the ammo with the best performance.

Clearly the 124 is a LITTLE better than 147 at energy at 50 and 100 yards. Yes it does matter, but, will it matter at 10 - 25 yards.? probably not.
Shoot what works in your pistol and has been proven to reliably expand

There's a website called "ballistics by the inch" and it shows the decrease in velocity/energy as the barrel length decreases. Very interesting. Check it out.

That was a very good site. Thanks for sharing.
