Really, cause I hardly notice any recoil on my .45. But then I am a big guy.

I have both, they feel nearly the same to me, but the .40 might be...sharper? Neither is bad at all.

Ok, well sheesh maybe I should've gotten a .45! What do you mean by sharper though? I read that earlier too.

It may have to do with the faster bullet? It doesn't kick harder, it just smacks a little quicker. The .45 seems to be a slower, duller sort of thud. Neither is going to make you worry about your thumb, they are both easy enough to shoot all day...
Either way, IMHO, the C9 kicks more...maybe because it is lighter? :angel:

i didn't really notice any diference in the recoil of the two. what i did notice is the highpoint .45 has alot less recoil than the tayrys .45 i had. infact my 9mm highpoint has more recoil then the .45 has.

OK, now all that makes sense. My mother has a .380, don't know the name of it, but that little thing is so inaccurate and darn near jumps out your hand. I was told then it was because it was smaller and had a shorter barrel. Longer/heavier guns don't buck as much. (and they have the nerve to STILL dog out a Hi-Point!) I'm glad I'm smart... I'da ended up with a Sig or Glock (nothing against them) Just like the two for the price of 1.

i have a glock and it's nice but i can hit targets more acuaratly with my highpoint 9mm i wanna get a .45 glock one day just to have one though.

what we are talking about here is lb/ft of recoil over time. i dont have exact numbers so ill paraphrase but youll still get hte idea

say the 40 has 100 lb/ft of recoil force over 10 m/s
say teh 45 has 150 lb/ft of recoil force over 25 m/s

the 45 has more recoil force, but it is spread out over 2.5x as long so it is less "felt" recoil. teh 40 has less recoil force but it is over a shorter time frame and thusly more snappy and sharp.

good discussion... i'm pondering buying an XD40 for IDPA & potential carry gun... the kill ballistics is near the same according to FBI studies at least, but friends tell me the .40 kicks less than .45 & let's them pop those double-taps pretty quick (is that a factor of the shorter time frame SW?)

plus i like the difference in capacity... of course I'd still keep my punkin thrower.

cycle time for a 40 is less than a 45, but speed of double taps is more about the weapon than the cartridge.

So if I understand you correctly, the average person could accurately fire double taps more quickly with the .40?

I have a JHP, and a C9 and neither kicks as much as my KT P3AT (380) but the 380 only weighs 13 oz loaded, with a laser, and plus 1 mag, very easy to carry, and most, like mine are very accurate at 10 yrd. or less, which is fine for SD. 45 is the most fun to shoot, C9 great combo (all around) good gun, and ammo a plenty and enexpensive.

In the context a friend was describing it to me, Springfield's XD series, the .40 falls back to sight picture more quickly than their .45. Likewise he found the natral timing of such was definately given toward a fast double-tap with the .40.

That being so (assumedly), it may not be the same between our .40 & .45 Hi-Points or Glocks, etc. His experience was that Taurus 24/7 series was similar, quicker for the .40 & encouraged me to switch calibers for this reason.

But to me the biggest deciding factor won't be the thoght of reloading .40 over .45, but will be can i scrape together enough pennies to buy an XD40 without taking bread from my kid's mouths... ^-^ First things first & I have no worries about shooting IDPA with my JHP, especially now that I fitted a 1911 mag to it.

by the math yes, in real life, hard to say. it requires much practice to be good.

Whoa.. Hold the bus for a minute, 1911 mag in HP?? Similar thoughts have crossed my mind, being that I have feed problems with factory mags, but how did you do it?? :brow: I have a JH9 with the old style heel catch, would that work for my gun?

Yeah, the 1911 mags are a pretty easy mod actually, as if the engineers that designed the poly frame planned it. I sent a PM to another member a while back bout it, can fwd to ya...

i dunno anything about the heel catch styled mag release, but prolly NOT work without totally different mod than i used for the JHP.

Good thread. I will make my next gun one of these 2 so I enjoyed reading about them. My only concern would be ammo costs compared to the c9. Whats the average cost of a box for either of these?
