@@clamum9648 Thanks! Your comments struck a chord with me. I have long though I should have become a coder. As a kid, I learned to code before most others. At 10 years old, I had a Commodore Vic20, but I didn't really get deep into coding as an adult. Software Dev pay is higher than ME, and you can work from home. A ME is a "traditional" engineer so we don't often get to work from home. Its also more hands on, so we are often required to be on-site and put hands on the stuff we design. However, I have friend who is a full time coder, and I know he's had some trouble in his career due to outsourcing to India. Meanwhile, for me, ME has been more steady. . Becoming a firearms engineer wasn't a conscious career choice-it was a job I needed at the time, and was years ago now, though last year, I did a consulting job where I designed another rifle. . Like any profession, the "cool" jobs pay less, as I am sure is true in coding. Designing firearms pays OK, but I make more money designing stuff in industries that are not well known or considered "cool". I make more money in industries that are considered "boring" by lay people, necessary/needed, and where talent is rare. . I recall running into a ME student back when I was working full time in firearms, and he didn't know that was a potential industry he could work in once earning his degree. He thought it sounded like the best job ever. For me, at the time, it was a job that paid the bills. .

This is a great video explaining the differences between straight blowback, and short recoil operation. If I may add, one little addition - in the early 20th century, there was actually a "blow forward" action, where the frame of the pistol stayed stationary, and the barrel moved forward upon the round firing, cycling the action. This was possible because of the enormous friction between the bullet and the rifling in the barrel. John Browning's short recoil operation makes use of this bullet / barrel friction in the same manner - in that, as long as the bullet is in the barrel of the gun, there is a forward acting force on the barrel. Simultaneously, there is a rearward force on the slide, from the pressure of the cartridge, which counters the forward force on the barrel. These two opposing forces briefly maintain the lock of a short recoil system, - until the bullet leaves the barrel and that forward acting bullet friction force disappears. It's a really ingenious system to keep the barrel and slide locked together until the moment the bullet leaves the barrel. Recoil springs can be made less stiff for larger calibers, making slides easier to rack. And the slide mass can also be drastically reduced. Thank you for putting these videos together -- they are entertaining and educational!

In the straight blow back, the case stays in the barrel until the bullet exists the gun. The reason is that the pressure in the case, and in the barrel, causes the case to swell. The swollen case is ceased in the barrel, and once the bullet leaves the barrel it will shrink enough to slide back out of the chamber.

Excellent, dude! The first vid I´ve found so far that actually explains which are the differences and, most important, WHY are those two widely uses designs different.

Always good to review the basics and I will not fault you for not doing a 1 hour video going over all of the locking mechanisms. I am interested in the gas delayed blow back systems. I have never fired one, but some say the recoil is managed very well by such systems.

Can we just take a moment to appreciate John Browing and how amazing his designs are? Gun nuts and military history nerds, such as myself, know the impact he made, but not everyone knows how revolutionary his designs were... there aren't many engineers/inventors/designers, etc. whose products have remained as useful, relevant and influential as Brownings... just the 1911 and the M2 .50 cal. alone are prime examples... the US military has used the M2 for 100 years or so with only minor adjustments made to the weapon, including adding a safety and a self-timing and head-spacing barrel....... pretty impressive IMO...

The only thing I can think of to add is regarding simple blowback pistols: the high pressure and heat in the barrel (once the ignition has begun AND while the bullet is still in the barrel) causes the cartridge case to expand. Most cases are brass and this causes some friction between the cartridge case and the inside of the barrel's chamber, which helps slghtly delay the rearward motion of the slide until the bullet exits the barrel and the pressure/friction reduces.

@@ostiariusalpha You are correct. Obturation has a very minor, if any, effect on slowing the cycling. It depends on the pressures involved, the case material (aluminum and steel cases have even less effect than brass cases), and the roughness of the inside of the chamber. I've read some manufacturers even tried to make the chamber interior rougher to increase the effect, but brass cases are just too soft to make this a useful experiment.

Love you're website. Great ammo prices, selection, and CS. Video's are interesting per usual.

I knew there was a difference between the two but never really looked into how or why they were different. As you stated, the Beretta PX4 Storm has a rotating barrel, both the full size and compact that is. The PX4 Storm Sub-compact, however, has a tilting barrel. I am guessing this is due to the limited space they had to work with on the sub-compact model compared to the compact and full size. Although, the one I own is in 9mm, so I cannot speak for the .40 caliber version. Awesome video, it's great to learn new things.

My guess on the difference in felt recoil: The blowback operated pistol has to have a stiff recoil spring, which means more of the recoil force is transmitted to the hand earlier. With the recoil operated pistol, the recoil spring can be much softer because it's job is mostly to push the slide forward again. That spreads out the recoil over a longer period of time.

FANTASTIC, I'm so glad I watch the channel to be a better informed pistol shooter. Understanding the mechanics and dynamics is important to me.

I frequently read and see in videos that many people believe a fixed barrel semi-auto handgun is the more accurate of the two designs.

If you're worried about accuracy with a handgun to the point where you're considering fixed barrel versus moving barrel, you're probably not a good enough shooter for the difference to matter. To be honest, unless you are a fixed mechanical rest or a robot, you are probably not a good enough shooter for the difference in a moving barrel to matter. Professional competitive shooters use mostly Browning-style tilting actions (most pro shooters use Glock pistols which are all Browning short recoil actions), which should in theory be less accurate than in-line Beretta-style actions, and pinpoint accuracy matters more for them than it ever will for an ordinary person.

Excellent video!! Beautifully explained! Thanks!!

It should be noted that the forces applied as the bullet is travelling down the barrel are so massive the spring strength is irrelevant. Even an extremely powerful spring, a spring so strong you'd need a crowbar just to open the slide a millimetre would hardly slow down the slide at all in the moment. This is because the FORCE applied on the slide is huge, it's as large as the force pushing on the bullet but the other way. Pressure acts in all directions and the base area of the cartridge is about equal to the base area of the bullet. Any spring applying even a fraction of that force would be far too strong to open the action. This is what's important about inertia, high mass resists high forces with low acceleration but over a long period of time this acceleration will mean the mass will just keep going so this is only good for brief periods. Springs keep slowing down (and actually apply more force when compressed more) so springs are negligible in the moment of firing but hugely important once the bullet has left the barrel and the slide is now travelling at quite a high velocity. If the slide is 100x the weight of the bullet then it will be accelerating at 1/100th the rate of the bullet (force = mass X acceleration). Acceleration isn't constant as bore pressure (therefore "bolt thrust") will vary but it will vary equally for bullet and slide, over time they'll have the same ratio of acceleration. This means a slide that is 100x as heavy as a bullet will have a velocity 100th as fast as the muzzle velocity of the bullet. The distance an object travels under a given acceleration is directly proportional to its acceleration. So if a slide is 100x the weight of a bullet, then it will have travelled 100th the distance the bullet travelled within the bore (so not barrel length but barrel length minus case length). Slightly more as the bullet is slowed down by friction with the barrel. So a 100mm long (4 inch barrel) will logically only open 1mm if the slide is 100x heavier than the bullet. That's probably very little travel. The case could probably travel much more than 1mm out of the chamber before any real risk of case bursting. Remember, the inertia of the slide must equal the inertia of the bullet. This is where the spring actually helps, it doesn't help keep the chamber closed, but it works on the slide over the much greater distance and time period which is as the slide opens all the way, the spring (hopefully) slow the slide down steadily over time so by the time the slide hits the frame it isn't going quite so fast. A stronger recoil spring means more velocity will be taken out of the slide as it's travelling backwards. A light recoil spring will will barely slow the slide at all before it hits the frame and transfers all that remaining inertia into the frame in an instant. This transfer of inertia will be REALLY fast, faster even than the transfer of inertia from the bullet to the frame of a revolver. This is how some straight blowback pistols can be REALLY snappy. One thing that shouldn't make a difference is recoiling mass as whatever the mass is, it must equal the inertia of the bullet fired. Even on browning-style short recoil guns, the barrel and slide moving together isn't any different than a much larger and heavier slide moving backwards in terms of amount of inertial imparted from the bullet. The difference with an unlocking barrel is you have the inertial mass split in half and stopped quite separately in time. The first when the barrel unlocks the barrel stops very quickly, then the slide is slowed down by the return spring before it locks open and dumps any remaining inertia into the frame.

Thanks for the slightly more detailed and mathematical explanation.

You said "lightning fast shipping at LuckyGunner.com", but I think the real world effectiveness of shipping velocity really depends on the mass and design of the shipment.

And how many tacos your UPS driver had that day.

Excellent video. I have been shooting for 40 years, but I never thought about this topic.

Thank you Chris. Third time I have watched your video on blowback vs. Recoil operated handguns. Very well done! Brain-damaged, not kidding one picture is truly worth a thousand words when trying to relearn things. I appreciate your effort very much.
