Velocities out of SR9 low. Why?

I came close to purchasing a SR9 but balked due to the barrel. The velocities coming out of those barrels are lower than all their competitor's pistol of the same barrel length. This seems to be the case with the Lc9 (or is it Ec9?). Has anyone else noticed that? What is wrong with their barrels?

I looked for aftermarket barrels online for the SR9. I didn't see any.

+1 Where did you get this idea? I've never heard or seen any information to support it.

Where did this info come from? First, you mention SR9, then the Lc9 and Ec9. Which are you talking about, and from where? One of those youtube "experts"? Or just the infallible Web itself?

If you are comparing velocity data from the LC9/EC9 guns to the full size SR9, M&P9, Sig 226 and similar guns, yes the velocities are going to be lower since their barrels are shorter. That is always the case. Compare them to guns with similar barrel lengths like the S&W Shield and Sig P365 and you will see they are the same.

Well good, guess I won’t have to worry about over penetration then when shooting my SR9...

Things have been hectic with me. I'll look for the info and come back.

I have never heard of this either. The only thing I can think of that would cause reduced velocity out of one gun vs another gun with the same length barrel would be if the gun that was shooting at lower velocities had significantly deeper rifling, allowing gas to blow past the bullet. In fact, that's what HK did with their VP70 models in order to allow them to work as blowback pistols, despite the high pressure of 9mm ammo. They had significantly deeper rifling grooves than a standard 9mm locked breech pistol barrel. This lowered pressure to safe levels, but it also chopped off a good chunk of velocity (something in the 175-200 fps range less that similar length barrels with standard rifling, iirc). Ruger SR barrels are not made this way, so, barring perhaps someone getting an out of spec barrel or something, this sounds like a case of bad information. I'm totally open to looking at the info, though, if you can find it again.

Obviously you have found it since you never reposted to this ridiculous thread in more than two weeks
