I have a cm9 and have read not to use a 147 grain bullet because of the shorter barrel. Are there any bullets designed for short barrels to expand at lower velocity?
Also just wondering what you would recommend between federal hst, speer gold dot, and winchester ranger t?
Can these bullets be reliable to expand properly with the right grain out of 3' barrel, if so what grain is that?
Gold Dot short barrel ammo,wife carries it in the 124grain in her G26.
* on the PPS I've fianlly got one that will shoot JHP without "Failure to Feed" issues. Two trips to S & W CS and nine months later they finally send a new one that can actually work in an SD event!

I like the 147gr Golden Sabers out of my PPS. If you look at the links above,l I think you will see that any "loss" of velocity is minimal or virtually non-existant. GS is very accurate for me, and as a non- +P load great for that quick second-third shot. Did I mention it cost #14.95 per box of 25?

I'm of the impression that the higher grain weight is the way to go with the shorter barrels. RA9T Winchester Ranger 147gr T-series HP for me in my Kel-tec PF-9.

If I were feeding a 9mm with a 3-inch barrel, I'd play with the various 147 grain ammunition offerings first and foremost.

I bought some 147 gr Gold Dot ammo recently for duty use in my Glocks, for better barrier penetration (as an Auxiliary, I have to supply my own sidearm and ammo). I wondered if I should use this out of the short (3") barrel of my PM9. Searching around, I found this:
9mm 147gr and Short Barrels - M4Carbine.net Forums
Bottom line is that the 147 gr should work just fine, as it suffers less percentage velocity loss, compared to the faster/lighter rounds.
Now I just have to get myself to the range and make sure it feeds!

I've fed my CM9 both 124 +p and 147 Speer GD. I emailed Speer to get their opinion on it and they replied saying some like, Out of the short 3" barrel the 147 will lose too much velocity to penetrate deep enough and probably not expand either. They recommended the 124 +p. I've been curious about this myself.
Edit: After reading 10thmtn's link now i'm a little confused
