    Putting in a new barrel

    I am thinking of putting a Glock 19 barrel in my 26. I carry my 26 and it seems that getting that extra 1/2" or so of barrel length improves the ballastics a bit.

    But that is not my question. I currently installed Big Dot sights on my Glock 26. It is sighted in perfectly. Very accurate. If I put a new barrel in, will that change the zeroing of the sights?

    Should have no effect since positioning and lockup will remain the same.

    Maybe, maybe not. You won't know until you drop in the barrel. Manufacturing tolerances are such that it could be right on the money, or substantially off.

    It shouldn't. At most you're picking up less than 50 ft/sec muzzle velocity*, so at defensive distances you would barely notice a change in POI due to the higher velocity. The actual fitment (lockup) of the barrel relative to the slide (think machining tolerances) will make more of a difference, but at most I think you might have to drift the rear sight a hair one way or the other.

    *based on "Ballistics by the Inch" (google it). I'm curious how much this new barrel will cost and the extent of your perceived benefit from the change.

    Any difference in balistics or POI will be nil in the world of SD. Now if you're shooting steel at 200 yrds with your Glock....

    The G19 barrel is completely compatible with the G26. It increases velocity without any effect on concealability or comfort, so there's no downside to installing it. I don't think you'll notice any difference in POI. Does it make a difference in a SD situation? It can't hurt.
    Gun control is not the answer. Gun control is the question. The answer is NO.

    I second this great idea of a longer barrel in a compact pistol. Many manufactures, like Beretta, design their barrels to protrude past the slide an extra 1/2".
    Aim for the Thoracic Triangle Area between the armpits and the base of throat.

    1. Shot Placement: Center Mass Between the Armpits & Base of Throat
    2. Heavy for Caliber Bullet Weight / Construction
