Of the standard pressure ammo, which has less recoil the 147 or the 115 grain ammo(standard pressure)I was going to carry the one, that has lesser recoil for quicker follow up shots ?

Perceived recoil is subjective, because the impulse of the recoil differs from loading to loading. Standard pressure ammo, though, I think most folks would agree that the 147-grain stuff kicks more than the 115-grainers. I'm pretty sure objectively this is true as well.

Neither weight is going to render fast follow-up shots difficult. I doubt you'd notice a substantial difference in your times unless you're an IPSC Grandmaster or something.

I would use which ever functions 100% of the time in your gun. The original loading for the 9mm was a 125gr. bullet and many guns still find that as a minimum weight to give proper functioning. Many of the modern US made 9mm guns have been designed around the lighter loading as have some that have been imported into this Country. I would try both and only use what works all the time. I've said it before and I'll repeat myself here again. I won't carry an automatic that hasn't given me 500 rounds without a single hiccup of any kind.

Depends on the velocity of each. Loaded to the same power factor, the 147gr kicks less. However, most commercial loadings do not load to the same power factor.

Here's a recoil calculator. Plug in your favorite loadings and see for yourself:

I am not worried about function I have 2 3rd generation 9mms

have you read this?

I don't see your point. It really doesn't make any difference what automatic you carry but in my mind it does NEED to be a proven one. No automatic goes on my hip before passing this little test. It also give me a very good chance to make sure I know the weapon as well.

I have always shot 147 grain better for some odd reason. I have gone down to a 124 grain TAP in 9mm for my Glock 26 because of the weight. I will probally do that for the SW3913 when I start carrying it if it functions well.

I was just bragging on the function and reliability of 3rd generation Smiths with a little humor thrown in. It was not a knock on you or your thread. Lighten up

While I carry 115 gr BlackHills in my Kahr MK9, I do have a lot more respect for the 147 gr bullet than Chuck Hawks.

Heavier bullets have never caused a malfunction in any of my 9's and have an advantage for penetration

.

eckmann,
Like the others have already said, the felt recoil will be greater with the 147gr bullet than the 115gr bullet. I also went to a 124gr bullet because I feel it's a good middle ground choice. I like the heavier bullet (than a 115gr) but the felt recoil is no more than the 115gr bullet. You also get more velocity than the 147gr bullet but not the screaming velocity you get from a 115gr bullet. With most Factory ammo a 115gr round will come close to or exceed 1,200 fps, a 147gr round won't break 1,000 fps but a 124gr round will achieve ~1100 fps. IMO a 124gr bullet is probably best for SD in a 9mm.

I prefer 147 because it has less recoil than the light bullets. I have faster and more accurate follow up shots.

It means something to me, and probably most others who have owned 3G 9mm's. They are HIGHLY reliable, and will even chamber empty rounds. I have found them to be much more reliable than my Sigs. This is pretty common info among S&W semiauto shooters.

Eckmann,

Most IPSC shooters in my club use 147 gr. in 9mm. Reason is that with same power factor (impulse) 147 gr. bullet will have less energy then 124 gr. bullet and hence less felt recoil. This is true only if power factor is same.

I shot a mix of 147 gr. and 124 gr. minor loads in the same string. The difference is very obvious. But if you ask me - I shoot 124 gr. loads anyways. I am just too cheap to practice with more expensive bullets.

You're not ethnically dutch like I am are you? BTW stay away from any caliber that starts with 4.
