I normally carry a Keltec P11 in a pocket holster.
Usually, I load Speer GD's for carry. (115 gr, I think?)
I'd like some debate on HP vs FMJ for carry in this caliber. Also, any projectile weight insights are welcome.
What ammo do you recommend or carry in 9mm.
To address the basics first: (You can skip to last paragraph for my conclusion.)
FMJ, JHP, or whatever you like will make no appreciable difference against body tissue, whether soft or hard. The wounds will be almost indistinguishable from each other. The JHP is what most will carry because it has enough penetrating ability to hit vital organs from almost any angle. It limits liability from overpenetration, unlike a 9mm FMJ, which can penetrate quite a bit, especially in NATO loadings. It also can penetrate external barriers and stay in one piece better than a semi-jacketed HP or other.
The JHP gives you the penetration you need, but not so much you will stirke the person down the block. As far as wounding, it will cause a little bit more damage than a FMJ, but not much. It really depends on what organ is hit, and most will not function properly with even a .22 hitting it. In 9mm, there isn't much a JHP can't do against someone that would be better accomplished using FMJ, so the limitation is really just penetration. In that respect, it (JHP) is the same, + or - a few inches depending on load, with the .40, .45, etc. We've all seen the charts/pics, I'm sure.
The Speer Gold Dot, being a bonded JHP, is significantly less likely to experience a core-jacket separation, especially after hard barriers, like auto glass. The down side is the copper "dot" in the middle can limit expansion, making it capable of overpenetrating easier. (Not something to really worry about, honestly.) Other JHPs are more likely to have the copper jacket peel away from the lead core, which can make it stop short, depending on the medium it is fired through.
In the end, ANY 9mm load will be equally effective against body tissue, even the WIN USA bulk JHPs from Wal-Mart. You will see no difference there. Why choose a premium JHP over the cheap ones then?
- Premium JHPs generally go through better quality control processes.
- Premium JHPs, esp. bonded, are designed to stay together better.
- A well-designed JHP often works better through tougher barriers, which might tear up a cheaper JHP.
- Premium JHPs are usually designed for optimal expansion for the weight and/or caliber.
I know points 2 & 3 go together, but thought it would be better said separately.
Your choice of the Speer 115 gr. Gold Dots is excellent. If it ever becomes a money issue, switch to the WIN or REM bulk JHPs and you'll be fine as well. I would also opt for overpenetration over underpenetration EVERY time.
