I just read this article (link), and wanted to get feedback from the forum. Apologies if this topic has been beaten to death. Does this article have solid merit? Seems like he has done his homework.

I generally shoot 180gr because that's what my Wal-Mart carries. What do ya'll shoot, and why (size, not brand, I know that's a whole different discussion)? Have you noticed improved performance (accuracy, reliability, etc) switching from 180gr to 165gr?

Thanks!

I have a P94 in 40 S&W and it does not do well accuracy wise with the 180 gr. When I step down to 155 gr it is dead on and accurate at 25 yds. I never tried the 165's as the 155's work well in my handgun.

Interesting read. In my very recent and very limited experience with .40 in my new Glock 23, I've found that 180gr Remington UMC FMJ and Golden Saber 180gr feels softer than WWB 165gr FMJ. Now learning that the FBI utilizes a 165gr HP, I'm going to test their specs and see how it feels. I currently carry the gun with 180gr Golden sabers but will likely switch to FBI load recommendations if they feel good...

Looks like another theoretical/quasi-technical argument to me.

How many times have you stood back up after being shot with a 180-grain 40-cal and said, "Ha! Your wussy 180-grain load didn't even hurt!"
?

Most guns tend to favor one brand, type, or whatever of ammo. I find that I can shoot 180gr bullet ammo best in my M&P40c. If I found a certain brand didn't shoot well in my gun then I would find a brand that did shoot well. As it stands, I cast my own for it and they shoot just fine for my desires.

Nice read...Thanks. I've used both, and can't say I notice any difference. I think I'll stay with the 165 gr. If nothing more, it looks like its a little safer..

Gabe, I read the article in your post and for the most part, I agree with the author's suggestions. The comparisons with a 10mm Auto have no place in this article ... totally different cartridge at a totally different working pressure .... apples and oranges.

There are three main things to consider with any cartridge and the order of priority changes with the intended use. For a "carry load", the absolute most important parameter is function. You just can't risk a load that won't function flawless in your gun. The second is "power" but with a 40 S&W, any factory load will meet or exceed self defense needs so it's really not an issue. Next is accuracy. For self defense you need "adequate" accuracy, not bullseye target grade accuracy. You could also add recoil, cost and availability of ammo, etc.

For a range/target gun, you aren't concerned with power and can tolerate a cartridge that may not function perfectly flawless so accuracy becomes more important.

In recent years, most law enforcement agencies that carry 40 S&Ws went to 165 gr "Lawman" ammo, which is rated at 1000 fps versus 1150 fps for "full power" 165 gr loads. The Lawman load is not perfect for all situations but it is the best overall compromise when function, accuracy, recoil, and power are considered.

IOWEGAN: As usually, you always make a lot of sense and explain things in quick, simple terms that are easily absorbed! Once again...thank you!

Well...all I know is that I've been shooting 165 grain JHP's because they are much more accurate out of my 4.02" Glock 23 pistol! I'm comfortable with the felt-recoil and my second (f/u) shot is better (ie, much more accurate!)

Personally, except when hunting, I've always preferred a moderate weight round in a pistol or revolver...they just seem to handle it better!
