I'm planning on building a G19 Gen 4 to be my new EDC. I plan on using mostly OEM internals for the slide and frame along with an OEM frame and slide that I plan on in the future milling for a red dot, barrel I was thinking about trying out a AIM surplus barrel as they're local to me and under $100. I have yet to order or purchase any parts yet so my question is what are some good sources to order from, just looking for the better deals around the interwebs.
Thanks

My G19.4 came fully built. Why buy something you don’t like?

1) You will find that it will be much, much easier to source Gen 3 parts.
The aftermarket build market is based on Gen 3

2) I would forget the AIM barrel and pay a little more for a KKM barrel.

3) Midway had the best prices for upper and lower OEM parts kits.

4) I used a Suarez slide but their shipping is brutal.
I bought during a free shipping event.

I never owned a Glock before building (assembling) these two.
34 parts....caveman easy and they are extremely accurate.

What do you mean? I can buy one already put together?

That’s certainly true about aftermarket being geared towards Gen 3 but there’s aspects of a Gen 3 that don’t like so that’s why I’m building a Gen 4.
Can you elaborate more on the AIM barrel and KKM barrel? The barrel is the one part that I’m willing to spend a little more on.
Why did you decide to use the Suarez slide?

The only thing I don't like about Gen 3 is the mag release button.
That was solved by using a Vickers button which is in between OEM standard and OEM extended.
I also used an Overwatch TAC trigger which reduces length of pull by a lot.

Also for peeps that have to order from out of state, AIM has brutal shipping costs and an unfriendly return policy, in my experience.

Can you elaborate more on the AIM barrel and KKM barrel? The barrel is the one part that I’m willing to spend a little more on.

Glock barrels are relatively cheap, so why buy an entry-level barrel when you can have a premium barrel for a few bucks more ?
And they don't reveal their "mystery maker" of these barrels.
KKM and Blacklist seem to lead the pack in the barrel shootouts.
I have found KKM to be an outstanding company as well.

Why did you decide to use the Suarez slide?

I wanted forward serrations and I wanted them done correctly.
Some aftermarket slides use 1911 type (fine) serrations....to me, they look weird on a Glock. (Lone Wolf and 80P Builder for example)
Some aftermarket slides put the forward serrations in the wrong place. (Brownells for example, on some of theirs)

Glock established the type and coarseness of their serrations back in the 80's.
To look correct on a Glock, it has to be a play on this design.
Suarez, after a few revisions arrived at the ones you see in the pic.

1) Serrations are OEM depth and width
2) Forward serrations placed in the correct location
3) Forward rake, matches grip angle
4) And here's the secret, 7 in rear, 6 in front (for balance).

And Suarez uses a sanitary, recessed panel (blood groove) for a well executed effect.
So in summary, it's an architectural thing.

Yes at your local gunshop. Glock sells complete handguns.

I’ll have to check into that, thanks.

The Gen III Magazine Release Button was mentioned above. I have the area around the magazine button scalloped on both of my Gen III's. That seems to have cured the problem of pushing the button in far enough without a longer button that can be activated by accident.
I have both Gen III's and Gen IV's. If I were to build another Glock I would probably go with a Gen III. I would buy a used complete gun and build it to perfection.
I would first go with a good sight set, or get the slide milled for an optical sight.
Then I would have the finger grooves removed and Grade II stippling added in a panel on the front leaving a border between the front stippling and the factory side panel. I would have Grade I stippling done (Gen III Only) to the side panels to make them a little more grippy. I would also have the area around the Magazine Button Scalloped at that time. A Gen IV does not need the side panels worked on.
I would add a One Piece uncaptured Guide Rod and appropriate recoil spring.
Then next would be trigger work.
Then a Cut Rifled Barrel.

For me buying a used Glock would be the way I would start on the project.

The mag release is the main reason as to why want to go with a Gen 4. I run a Vickers Tactical mag release on my G43 that carry now and I like the larger surface area and I can roll my thumb across the mag release instead of pushing in. Appreciate the input.
