    Just curious if using a G19c for defense would suffer enough velocity loss as to not have reliable expansion of defensive ammo.

    My main carry loads are Winchester T-series 127gr +p+, Federal 124gr +p, and Speer Gold Dot in 124gr+p.

    I used Rem 115g +P in mine and a 33 rd mag. If the first round doesn't work keep pulling the trigger.

    I suggest that you consider using the ported barrel at the range and use a standard barrel for carry.

    Velocity loss is in the 5% range. Premium JHP ammo will expand just fine.

    I wouldn't mod the gun if its for carry in court they would say he modded a 19C to get more killing power or some other BS.

    Chronograph the loads with your G19C to find out how fast they're actually going, and call the ammo maker to inquire about what velocity is needed for reliable expansion for the specific load.

    Is there a loss? Yes and it is miniscule. The Glock ports are not large.

    For a high power rifle, one loses about 25 fps for every inch of barrel loss. Magnums are a tiny bit more.

    Butch to the rescue again.

    I just got a 19c. Thanks for the links. I figured it would be similar to a short barrel.

    I don't know about velocity loss being an issue since the 19C ports are not much farther back than a standard G26 barrel's end. What I do know is that my 17C sometimes has trouble cycling standard power rounds with the ported barrel installed. It does not have those problems with an OEM unported barrel installed.

    If you carry with the ported barrel I would carry with +p or +p+ rounds like you listed just to make sure the action cycles everytime you need it to. As long as it cycles velocity should not be an issue.

    The gun is not modified by installing a non ported factory barrel in it. Glock approves of using standard barrels in their C models I know because I used to have a 23C.

    No, not a concern with any standard ammo. Only downside of the c models is additional cost to purchase. Fine for plinking and ccw, fine for LE use. If you have a c model that isn't cycling, you have a separate issue that you should be concerned about. The porting isn't causing it.
