Barrel longer than the slide... Does it increase recoil?

Hey everyone,

Some handguns have the barrel a little longer than the slide. Some examples are the glock 19 or ppq m2 here in Canada. It says threaded barrel.
I imagine is to meet the minimum barrel length requirement for restricted fire-arms.

My question is, will the barrel longer than the slide have an effect in recoil? Or is it irrelevant?
 
A longer barrel in a handgun will increase the recoil, but small increases in length yield small increases in recoil.

For those 2 guns in question, it's irrelevant.

I agree. And if recoil was relevant, and someone is looking at minimizing recoil, the weight difference between a polymer and steel framed pistol would be a better focus than a few mm extra barrel length.

On the other hand, the threaded barrel will also allow for the easy use of a compensator...:p
 
Good to know.
Thanks everyone for your knowledge.

My wife shot with a glock and a cz at the range a few days ago, she liked the CZ better. I don't remember the model, we know that it was an all steel gun.

Both her and I are new to handguns and firearms in general.
 
depends on the powder burn as well, a longer barrel will give more time to contain the burn and allow pressure to build, depends on the powder and the amount. Once the pressure peaks the rest of the barrel is just friction. if you look at the website http://www.ballisticsbytheinch.com/ you generally note that pistol calibre carbines do best with a 16" barrel, sadly our laws make 18.5" barrels desirable,.
 
interesting topic.

i picked up a compact S&W last year and compared to my 4" and 5" barreled S&W i dont notice any increase in recoil.
in fact i find the compact one easier to shoot.

little snappier maybe, very slight difference, barely noticeable difference.

couple regular length ones too boot

same as above, just more artistic.

on a related note i also have the same in 1911.
again i dont notice any difference in recoil shooting them.

couple even shorter slide 1911's ive shot as well (my dads)

As noted already, the added length increases muzzle velocity, which tends to increase recoil. A longer barrel would also add mass, which would reduce recoil, and the added length increases its rotational moment of of inertia which would tend to reduce muzzle flip. I'm guessing that all of these would be unnoticeable to the shooter, at least at the small increases we're talking about here.
 
Longer barrel would increase velovity, and pressure of the overall load.

extra weight on the barrel will compensate a bit on the muzzel flip, but i would think the heavier barrel would cause slower lockup times also.

a compensated pistol locks jp slower, with the weight up front. But at the same time, you need added pressures to make the compensater work more efficient.

that is why 9mm major or a 38super on a compensated gun is so effective with a lighter bullet and higher gas pressures.
