One of the users here asked about 9mm Gold Dot 124 +P velocities in a G19 vs. G19C (factory-ported model). I had a partial box of this ammo, along with some other loads, so I ran them all over the chronograph to see how they compared in the two pistols. Temperature during testing was 68-70 degrees F.

The loads:

The Glocks (G19C has NP3 coating, but coating is not applied to inside of barrel):

The setup:

Not a great deal of speed lost, with the compensated numbers.

I picked up another compensated barrel today, a 19C, for use in my 23C.

I like the feel of the compensated fire over the non compensated fire.

So close, I'm not even sure you can point to the compensator. I've found two of the same gun having bigger spreads. Just the difference of one barrel to the next.

Numbers not theory or speculation. Thanks.

I shot a borrowed 22C in an indoor range against a black background. I had no problem whatsoever with flash. I liked the very slight reduction in muzzle flip.

If I were to choose between a 22 or 22C, I was choose the C. BUT, I still would carry my Revolver.

What loads were you shooting? Some powders are better than others. Most of the time, flash never bothers me. If I load anything with Blue Dot, I feel like I could kill something and cook it at the same time. :embarassed:

Win 296 is the same way (in magnum revolvers; not suitable for most autoloading pistol cartridges).

Even with magnum cartridges, H110 / 296 is a dragster - throttle is open or closed. Nothing in between.

Actually tried Blue Dot in 9mm once. Didn't perform any better than my normal Unique loads, but it sure was an impressive fireball. :supergrin:

Not your typical C thread where internet experts warn of severe burns, deaths of family members being torched and permanent night blindness. Refreshing.

It turned in that direction in the other post. Love all the numbers DJ Niner put up though, sure others do too.

I put a 9mm compensated barrel in my G27 just so my wife can handle the +p+ ammo in it.
