serial #s on a glock?

[Domingo]

question about changing the slide and barrel from my glock19.
I have a glock 19 all #s match but Im thinking of tradeing my slide for a glock 23 slide if I do that will I be breaking any laws since my slide and barrel are not going to match my pistol frame, when I bought my glock it came with 2 empty shells,
thank you for the input

Slides and barrels are not the regulated parts of a handgun. Only the frame. This is true at least in the US. Other countries have different requirements and that's why manufacturers, such as Glock, put the serial #'s on frame slide and barrel. With what you want to do is perfectly legal and many people will swap barrels and slides on their Gloxks to be able to shoot different calibers.

Yup.

Might hurt resale value if you plan to sell your franken-glock one day. Some prefer all three components to have matching serial numbers.

The two empty shells are to prove to you that the gun was test fired twice by the GLOCK factory, and passed inspection.

As a side note, aftermarket barrels and a Lone Wolf slide may be a solution that is to your liking as they don't have serial numbers. You will still almost certainly reduce the resale value though.

Legal, but I would keep my slide. 9mm > .40 anyways.

Go for it. If turns out you missing your 9mm after, you can always get a conversion barrel from vendors like Lone Wolf. They only cost $100 new.

IMO hold on to your OEM Glock parts for that day when you may want to sell.

I try to buy up as many reasonably priced Glock frames as I can find to go with all the extra slide assys I have!

While this is true to GLOCK and a lot of firearms out there its a bit of a blanket statement to say only frames are the registered part in the US.

For example the receiver (barrel and "slide") of a Ruger MK series pistol is the registered part not the frame.

I haven't heard of a 9mm to 40 conversion for the Glock pistol. It's different from converting a .40S&W DOWN to a 9mm
There will be an issue with the ejector angle on the 9mm v. .40SW change over.
.40SW to 9mm conversions are quite common and only replace the barrel, recoil spring and magazine. They compensate the different ejector angles with a slightly off set chamber and bore.
The conversion from 9mm model 19 to a .40 cal. will take more than a simple barrel swap.
I see a slide change (to accomodate the larger .40 cal rim/case size at the breech face) a trigger housing change to get the right ejector angle. When it's all said and done you'd be better of trading/selling the M-19 and buying a M-23 and if you wanted to shoot 9mm out of the 23 it's a way simplier/cheaper conversion IMO
As far as matching numbers....only a collector will care.
