    Personally I prefer standard pressure 147 gr in the 9mm, and think the standard pressure in 124 would be fine also. IF you really wanted to try +p and can't find them lcally, look at SGAmmo.com.

    That's where I've been looking, and where I bought the standard pressure stuff.

    SGAmmo.com has Remington 124 golden saber bonded +P on sale at $11.95 per box of 25. It drops to $10.95 if you buy 20 or more boxes

    Yep.

    Most +P+ is rated only 10% more than a typical 9mm ammo. Is that 10% going to be a BIG difference, not likely . However it will cycle your slide faster and may not work well in the PM9 at all... causing misfeeds, etc.

    Shoot what works well for you, that your gun likes, and is easiest on your pocket book.... and worry more about "accuracy" and technique. Personally, I like the 124 gr, and that's all I use.

    I have loved the 124gr+P GDHPs for many years in my 9mms. It's just my way to go pretty much. I may not be giving you any good reasons, but I have my own. Stick with what works best for you.

    Of course... two days after I post this, I get an email from SGAmmo saying that they have 124gr +P in stock for both Gold Dot and HST. Go figure.

    I generally prefer the mid-range weight (124 in 9mm, 165 in .40) with the highest velocity available. I just wanted to know if I screwed up by accepting the standard pressure instead of waiting for the +P. In other words, I share your preference, but would you feel like standard pressure was a bad choice if +P wasn't available?

    The gain in +p is minimal in the top rounds. Bullets are made to work well in the of round. Ranger , HST are fine. Gold dot has the most real data in police use as its what most departments use. The goal most makers are shooting for us the 125 grain 357 mag load. Historically the best SD round

    After watching some ballistic tests from "Tnoutdoors" on you tube I switched from the 124gr +P Federal HST to the 147gr standard pressure Federal HST.

    Give it a look!

    I carry 147gr+P HSTs in my SR9c, but that isn't because I initially wanted the +P. I ordered +P because that was what was available at the time. While I think standard pressure is perfectly adequate, I do not regret my decision going with +P. With my 3.5" barrel, the +P would certainly increase the velocity compared to a standard load in the same barrel length. +P loads generally have more expansion and less penetration. I am okay with less penetration than a standard load, but I really prefer a bullet that expands to a large diameter. This is my primary reason for picking the heavier weight with the HSTs. A larger diameter means a larger damage path, cutting nerves, veins and arteries. 147gr HSTs regularly expand to over .70" in tests.

    That makes me wonder... my 9mm is a Kahr CM9 has a 3" barrel... I wonder what velocity advantage there is in such a short barrel, will there be unutilized powder left when the bullet leaves the barrel? In other words, do I lose any advantage that might be present in the +P by using a little pistol?

    This chart gives some insight into bullet velocities as they pertain to barrel length: BBTI - Ballistics by the Inch :: 9mm Luger Results

    Shorter barrel = lower velocity.

    That spreadsheet looks great, but they don't have +P and standard in the same bullet by the same manufacturer... anywhere. I'm just wondering if you still get greater velocity going to 3" barrel between the two loads.

    I might have to bust out the chrono on this one... but I need to do some creative purchasing
