Gun comparison test

First round on target is the most important. As they are the same size. No difference. As for the second shot time would be negligible if any.

I'm confused. What are you trying to accomplish? I really doubt that any difference would be so significant that it's going to make a difference. It also sounds like you're going into this experiment with a preconceived idea, and that subconsciously may make you do what you already expect to happen.

[Unsilenced]

Well your first step would be to buy an actual shot timer if you want to have any chance at potentially valid results.

Assuming you are on private land and not a public range...

Try it one handed while you are advancing, retreating, turning, seated, or moving sideways (please don't shoot yourself). That would be a more realistic test assuming we are testing real world situations. Feet and grip not set will amplify the recoil differences. In real world situations most shots are taken one handed even though everyone is trained to shoot with two.

Police who stand still get shot much more often. The point of self defense is to not get shot, not taking a hit to get a hit.

The above is surprisingly great info suggested for calguns.

I can understand you are trying to do a simple test. So do the one you want to do.

Confidence through excellent graspe of the fundamentals of shooting is a huge part of being successful in a gunfight. But even that pales in comparison to simply making the choice to have either a CCW or arm yourself with a firearm.

Eeh NO....a .40SW is no slower that a 9mm. I own 1911s in 9mm, 40SW, & 45ACP...when doing USPSA drills like the doubles drill or a 3 targets 1yd apart at 5-15yds my times are comparable. It's all about your grip.

I've also shot M&P Pro's in 9mm & 40SW...couldn't really tell them apart....

My plan was simply to get a recorded time for each. I always here people saying the 9 is easier to get off your next shot, ect. Thought I would put numbers on it and see for myself. But as I started thinking about what to do, it just seems at close range any difference would be negligible.
I will do it anyways to see for myself. Testing will be done in my backyard, maybe I should by a timer, but the phone app works pretty well.

Nothing wrong with replicating fun experiments to see if you get the same results - as long as you can do it safely. If you have a backyard that you're allowed to shoot in, then consider me jealous .

Why not try different distances? 6ft, 10ft, 21ft... see how the results change.

everyone is going to be different, and have different tolerances to recoil, so it will be a useful test, even if it only applies to you.

for paul harrell, the difference in speed for 9 shots of each was 1.3 seconds.
6.7 sec vs 8.0 sec using 17 vs 22

Agree that everyone is different so blanket statements aren't useful.

The difference in Paul's results is almost 20% faster with the 17. Me being the judge, I say that's a lot.

Ok, so in theory ... wouldn't a factory .40 round have more energy than a factory 9mm? Wouldn't that result in faster slide movement from recoil to battery? Then if you have an iron grip that lets you keep your eye on the front sight ... shouldn't the G23 actually be FASTER to the second shot?

[SnWnMe]

There is also the variable that you are more proficient with your 19 than your new 23.

Your grip might shift with the increased recoil and throw off your results.

How do you account for that?

Seems correct IMO. But the key phrase is "if you have an iron grip that lets you keep your eye on the front sight". 40 is going to have more muzzle rise, requiring more time for the front sight to return to target. You would need a vice to truly eliminate this variable.

Its not perfect science. You do your best to be consistent and take the info for what it is - a general indication of how you perform with the different calibers.
