Pistol Round accuracy comparisons
Posted on 2/3/22 at 12:15 pm
Posted on 2/3/22 at 12:15 pm
Which pistol caliber is the most accurate? Is one calber inherently more accurate than another?
9mm vs .40 vs 45acp vs .357sig vs .380acp
Or is it negligible at common pistol distances?
25yds
50yds

I don't think it really matters at common pistol distances.
More important is the gun you're using. I have a 2011 that I built that is incredibly more accurate than production pistols. That gun however is extremely tight with a trigger that would rival what you would find in a good rifle.

Of course that is more important. But say you have 2 pistols of equal quality, Shooting the sane style bullet. 9mm vs 45acp. Shooting at 50yds. Which round is more accurate?

Likely negligible at any distance.

9mm is faster. Stability would be better the further you go out.

Neither one. Both are short straight wall cartridges that headspace off the case mouth.
I guess you could nerd out on what the chamber and throat specs of each one are and all that shite, but in reality it doesn't matter. Cartridge and chamber design only come into play when shooting so far that very obscure differences become noticeable. For almost all normal shooters, the particular cartridge used is an entirely irrelevant part of the accuracy equation.

I’d say the pistol has more to do with accuracy and repeatability than the round itself. My guns personally they perform about the same but I have a 9mm sig. with a trigger job is snappier than my stock 45 XDM but I shoot them about the same the 45 maybe a hair better because it’s a bigger gun and.

I think it would be negligible. However, I also think if you are talking firing in succession, different models/brands/calibers/sizes are going to recoil and reset at different angles, or in a different way. Like when you shoot and the gun recoils where does it come back down at? That affects accuracy by a lot if shooting more than once quickly. Trigger weight definitely plays a factor in that as well. I am sure there is a technical term for what I am referring to but idk. However, this is more a form and experience issue and learning the pistol over time.

Accuracy isn't going to change at all. Precision may be improved on quick follow up shots on rounds with less felt recoil. The biggest precision improvement you are going to see in a pistol is going to a bigger, heavier gun. Even the longer barrel for the longer site radius is not as good as a simply bigger, heavier gun to keep the gun flat for follow ups. Compensators are also great, and well suppressors are best for keeping guns flat while shooting.

I did some research and a poster on a 1911 forum stated that the 9mm snd 38 super are actually tapered cases and therefore are inherently slightly more accurate than 45, 40, 380 and etc.
Link for reference to the thread on same subject

Most pistol engagements happen within 5yrds. Get a 45 acp and get good at pulling it quick and unloading it within a 3" group quickly.

Ah, cool. Did not know that. I had heard before that 38 super was supposed to have been designed for accuracy.
Makes sense that being tapered could help a little bit

Accurate. I found out why in academy training and requalifying every year, we spent so much time at 2 yards.
Upon signal you will take 1 step back, draw revolver from hoster, and fire 2 rounds from ready gun. Re-holster. ( Ready gun is gun out front but lower than level that you can use sights. Its an instinct shoot. ) This was repeated over and over . I found out why years later.
Repetition develops instinct.
I would think that 9mm accuracy would be good from a Beretta 92F, with the 5 inch barrel, and trial & error test ammo.

Yea, I'm not hitting shite with a pistol at 50 yards. Based on the range I'm ok at 30. I'd prefer to not use a pistol at anything over 20.

Hell, at my local indoor range I have trouble seeing 25 yards down Bc there’s just not enough lighting and I guess my eyes are weak. Even so, I know I’m not good at that distance with a handgun. But if I had to choose a handgun for that distance, I’d pick the heaviest, longest barrel revolver I could find, and it’d be either 22lr or 38spl. Shoot it single action.

If you're taking about hunting (and I assume you are, since you listed some pretty long distances), I'd think the gun and your skill set will be bigger accuracy factors - but I've never hunted with a handgun.

Post course involved 2 yards, 15 yards, and 25 yards.
I get the 2 yards, because in the field, we maintain a reactionary gap of 6 feet. No one gets closer than 6 feet.
Now, back in the 1990's, every leo underwent in service sensitivity training, that said certain ethnics gesture differently. Arabs like to get close, etc and we were not to take it as a reactionary gap intrusion.
I don't think so !
But i get it, the closeness of a field interview gone bad.

That one step back was supposed to create distance.
And knives ? Do not under estimate a knife wielding perp.
Surviving edged Weapons training showed that. A cadet with a rubber knife closed in on you, as you were expected to drop a mag and reload, to kill him. I beat him, but only by back stepping to buy some time. They can be on you in a second. Boom !
