hornady has used canellures on almost all of their bullets from the early years, it's based on their interlock trademark. Critical duty appears to have them. You'll note that the critical rounds are identical xtp bullets that have the plugs in the tips. This obviously serves a couple purposes, and they probably do enhance performance.Thanks for all the helpful info form everyone, your post was probably the most helpful.
Does Hornady use crimp grooves for 9mm in their Critical Defense/Critical Duty line as well as XTP?
@Screwball Where did you come up with a 642-1 in 9mm. I have one but I had a 940 cylinder installed in a 642 to make it. Standard catalog of S&W calls it a 942.
Personally, if you have these concerns I suggest you reconsider going to a .38 with plus Ps and be done with it.
You've already planted enough doubt in your own mind to just forget about it.
Unless your someone who doesn't like semis but still wants to utilize the superior 9mm with faster loading moonclips in a revolver. It's nice to have options if your a wheelgunner, especially at prices 9mm is going for vs. .38special. I still have my revolvers in .38special so it's not like I'm stuck with 9mm.I tend to agree. I like 9mm but I don't like uphill battles. So I keep life easy. I use 9mm in semi-automatics and .38 special in revolvers. The +p gets a little closer to 9mm in power. To exceed it, the OP could do double-duty with a .357 magnum. For less recoil and a little more capacity while still saying on the plus side of 9mm, go with .327 Federal. With any of those choices, the issue generally disappears.
Have you had a problem with this? Have you tried to make it happen? If not, why make up things to worry about? If you have, what have you found that alleviated the issue? IME, "bullet creep" or "bullet jump" happens with reloaded ammo with heavy bullets with light crimps. Factory ammo generally has enough crimp to avoid this. If you are super worried because this is a carry piece, use military 9mm ammo, it is sealed in place to avoid bullet movement in submachine guns.My question is which 9mm bullet is less likely to loosen under force of recoil out of a revolver, the lighter ones or the heavier ones?
Who are you referring to? I never said any such thing.Why in the name of God do you believe that a .38 with plus p cold do everything a nine can do without also possibly cause bullet jump? It will be larger, heavier, weaker, and not necessarily stronger on the grip than a crimped xtp..

I'm one who believes that it can work, I agree that you can certainly use it far more cheaply. I never see .38 brass layng around at the ranges.
I'm not sure where you are getting your stats from. Buffalo Bore is known for hot loads and may be the exception but it's generally not true that .38special +P is the equal of 9mm. In Luckygunners extensive tests, only two .38special +P rounds out of three dozen or so cracked the 1000 fps mark, and one of those was a +P+ and both were out of a 4" barrel. Compare that with his 9mm tests where many rounds well exceeded the 1000fps mark and that's just standard 9mm, not +P. http://www.luckygunner.com/labs/revolver-ballistics-test/Weaker?
Lets compare apples to apples in the .38 +P to nine comparison.
From one manufacturer, Buffalo Bore and their hottest load for each:
9mm +P out of a Sig with 2.9" barrel was 1024 fps with 147 grain = 340 ft. # ME
.38 spl +P out of an LCRx with 3" barrel was 1087 with 158 grain = 400 ft. # ME
Hardly weaker!
Sure, maybe if you compare a glock 17 to a snubby 1 7/8 LCR, but even then that is apples to oranges.
9mm +P out of a Glock 17 maybe gets 1100 fps with 147 grain = 394 ft. # ME
.38 spl +P out of Ruger LCR gives 1024 with 158 grain = 360 ft. # ME
I'm not sure where you are getting your stats from.
Luckygunner tested close to 40 loads in .38special+P and 9mm, with many well known and some hard to find law enforcement loads. I think that's more then adequate to come to a conclusion about .38Special+P vs. 9mm. Just because he didn't test some boutique brand that strives to make the hottest loads possible, some that are probably dangerous like BB's .380acp+P and shouldn't be sold, doesn't negate the results.Lucky gunner never tested BB loads, so it looks like he was afraid of showing their results because he is in the business of selling other brands of ammo.
I totally disagree. In no way is a loaded 9mm moonclip anywhere near as heavy or bulky as a .38special speed loader. There is nothing wrong with speed strips but even those can take up more over all space in a pocket except that they are flat, which makes sitting with them possible if wearing jeans. I could probably carry more ammo via loaded 9mm moonclips in a side cargo pocket then with .38special speed strips. I only carry speed strips when wearing pants with no side pockets and a T-shirt and like you, in the watch fob pocket where I can usually fit only one of them while still be able to access it quickly.While I do carry speedloaders from time to time, and the bulk is similar to a moon clip, I prefer to carry in a flat speed strip in my watch pocket and nothing can compare to that in minimal bulk.

Speed is important. Speed matters. Speed kills armor. I've seen demonstrations of 9mm penetrating barriers that .45acp could not. It's why light fast loads like .22mag can possibly penetrate 3A body armor while the larger, heavier ones can't (see Paul Harrell's body armor tests).You can't go by speed alone. Many of the claimed over 1000 fps of the 9 mm are lightweight bullets compared to any 158 grain tests!
