Worlds Collide: Does Barrel Length Matter? (Part 1 of 2)

Rob Leatham
Duration:   4  mins

Description

For viewers who’ve been craving a true Worlds Collide between the contrasting viewpoints of competition shooter Rob Leatham and defensive shooting instructor Rob Pincus, here it is.

Though they do start out in agreement: whether for competition, handgun training, or defensive shooting, an extra inch of barrel and slide on a handgun matters and is a good thing. But do they agree on why? Rob L wants the pointability and the sight radius. Rob P wants faster follow-up shots, which come from more weight out front due to the extra inch of length.

Follow-Up Shots

Rob L, however, doesn’t think the extra weight out front is what makes follow-up shots faster, and he wants to define faster follow-up shots. What matters is not how fast a shooter can shoot at the target, it’s how fast he can hit it. The longer sight radius shows the shooter his error better.

Rob P contends that Rob L is assuming the shooter is looking at the sights, and that in defensive shooting, the shooter is often not looking at the sights or not even aware of them due to the high-stress nature of the incident.

Perfect Sight Picture

Rob L counters that Rob P thinks he is looking for a perfect sight picture, and says that in competition shooting, he doesn’t have time to obtain that. Due to the speed of competition shooting, Rob L needs the longest sighting plane he can get, hence he prefers a handgun with a longer barrel.

Rob P asks that if Rob L is not using a sight radius, does the longer slide still contribute to faster follow-up shots? Answer: absolutely, because he can point it better.

Then they test this idea with some live fire and confirm that both of them shoot slightly faster with the pistol that has the longer slide and barrel.

The discussion begun in this video continues in Part 2: Aiming vs. Sighting.

    Take the sights off these pistols, both front and rear. Then they CAN'T use the sights. Longer slide will still be better.

We've talked about this, now I'm doing the whole gun design thing. You shoot guns a lot better than I do but we both agree, that an extra inch of barrel matters. Absolutely. Okay. But do we agree on why? So here I have a XD mod two four-inch Right Here I have an XD mod two tactical five inch, Right? Why does the extra inch of barrel and slide matter? Well, I don't care about the barrel length. I think the increase in velocity for especially from my world, doesn't make any difference. I want the point ability and I want the sight radius. You know what I want? What Faster follow-up shots. I want more weight out in front. Well, I'm not certain that weight alone is what does that. It may not be. What do you think else does it? Well, I think faster follow up shoots. Let's define faster follow-up steps. This is where it leads to inevitably, Here we go. So when we come faster followup shots, it's not how fast I can shoot at the targets, how fast I can hit it. And the longer sight radius shows me my error better, right? So like, if it wasn't true we'd all have a zero sight radius Pistol we'd have one site stuck in the middle of it. We wouldn't want any site rating. I think those are called red dots but... I think you're right. But those move too, Okay. So like there's an assumption in your premise. Okay. The assumption is we're looking at the sites. Well, yeah, I am, but I don't always stare at the sites. Right, sometimes in defensive shooting, we're not looking we're not even seeing them we're not looking at them. We're not, there's nothing, no reference there. And that's why I go back to I think I hear what you're saying that yes you can get that faster site radius for us for a correction or for a verification. But you're looking for a perfect site picture. You're expecting me to look for a perfect site picture. Here's the deal, I don't have time for that. Correct. When it happens quick I need the longest siting plane I can get. And if you aren't using a site radius does a longer if the site radius is irrelevant does the longer slide still contribute to it? Ooh yeah, I can point it better. Okay. Absolutely. Should we test it? Sure. All right, let's do that. We've got a five... Wait look inferior to you in any way when we're done? Other than fitness. Besides fitness. Oh no. You know how I measure people, right? I don't use a timer. I measure them purely by height. That's about makes sense. I would do that too. I would do that too. I do it differently. Okay, here we go. So what are we doing? You're gonna shoot, you're gonna shoot two shots into any of the big poppers as it goes down, right? So you're still putting two shots into it, Dang, dang at the same target Dang dang and we got three at the same distance. So let's go with that. Okay. Dang on the same target. Dang dang on the same target. Don't cheat. What's the starting position. Just like that. Alright. Okay. Alright. Ready? Yep. All right, so your split was 0.2, three. Okay. All right. Put that gun down, leave it hot. You leave guns hot sometimes on the defensive range. There you go, you got that you want this? That a lot of bullets. Yeah. All right. No matter how many I may need. All right, here we go. Same thing. Stand by 0.2 one. That was fast. That was so fast. It was fast. You like unloading guns. Why are you guys always so quick to unload guns? Give me that. All right. It's cause I knew you were going to have it in your hand. So then I'm scared. Right, That makes sense. I wanted that little... Yeah you haven't, 'cause you don't see me shoot nearly often enough. Here we go. Standby. Standing by. Ready? Ready. 22. 0.22. It's fast. Say it You're faster than I was. You're faster than I was. Fair enough all right sorry. Here we go. You said it was ready To be fair that target though is was a quarter... Its like an eighth of a yard yard longer, right yeah. All right, Here we go. You should be ready. Ready? Standby. Did you see that the pressure was so on when the big Rob shot Both his targets. He got two hits on each the other Rob maybe not so much. So obviously your whole premise of the longer sight radius... I wasn't using the sites. Well, maybe you should have, Maybe I should have... What's the time The time was 21. 21. So you're as fast as I am, So I was as fast as you were but we were both slightly faster with this slightly longer slide and barrel. You saw the site in the second shot, liar. I'm not aiming. There you go. I'm pointing.
