Nice builds. What kind of drill press set up are you guys using?

DO NOT USE A DRILL PRESS. Seriously.
The way these frames are built, and the material used - a drill press will drill too cleanly, and the pins will walk out.
Drill it by hand, one side at a time. DO NOT run the bit all the way thru. The slight misalignment actually is beneficial, as it keeps the pins snug in the frame. Poly80 even advises against the drill press on their site and in the instructions, for good reason.

That's good to know. Now I can buy more of these kits now that I don't have to get a drill press to build them.

I’m by no means technical but if you need any help I’ve got a few under my belt and would gladly help

Out of the 'few' I've done, or assisted with, only 1 had an issue with the pins trying to walk out. And it was the one where I ran the bit thru both sides in one pass.
Fixed that by 'pushing' material in around the pin holes with a soldering iron, lesson learned.

That would be awesome.
I will keep that in mind when i'm ready to build one. I still have some parts I need to get first. I just ordered my first one today in ODGreen. I never heard of these till I saw this thread today. Where is a good place to get the slide and parts kits? What brands are good? Thanks in advance.

Lower parts arrived Saturday, just need a barrel and I'll be all set.

Slides, factory seem to be the least troublesome on new builds, but aftermarket is cheaper. Parts kits, I snagged a bunch of frame parts kits when Midway had them on sale for $49 a piece. There's plenty of vendors where you can find them, but sometimes availability is an issue.
Depending on desired caliber, the sky's the limit. I may end up just selling my G31 slide. Seems I prefer the 32.

Question for you:
How different are the ergos?
I'm a SIG guy, for the last 20 years or so. I've always owned and shot classic P-series SIGs. I competed with them, etc. Glocks, with the different grip angle, just never worked for me as instinctively. I know that I could re-train myself to shoot them well, but with all the SIGs in my safe that just doesn't make sense.
I'd like to try my hand at a P80c, just because, but am I going to run in to the same "issues" as with standard Glock ergos, or are they different enough?
What I really need is for one or another of these companies that keep promising them to actually offer one of their 80% P320 kits. I freaking love my X-VTAC.

The Glock being compared is a gen 2 so keep that in mind. I added the sig in there for you but the sig is obviously a full size and both glocks are 19s.
The ergos between the glocks aren’t really different. The P80 just took the upgrade ideas and ran with it. Undercut guard, no finger grooves, bigger beaver tail, and i got the RTF frame. I believe the P80 frames are a little thicker as well. I didn’t 100% confirm this statement but with a factory Glock i need a grip sleeve, with the P80 i do not. My pic makes it look more thin but that’s my fault and the factory 19 has a grip sleeve. The P80 also has a large bump at the bottom of the mag well for your grip and the mag well has a slight flare compared to my gen 2 Glock. I didn’t pull out the gen 3 19 i can do that later just trying to show you the differences real quick
Keep in mind it’s a Glock copy so it won’t have the ergos of the 226 i tossed in there. It isn’t 1/4 as comfortable as a CZ75 but they are still decent and I’m happy.

The thing that drives me crazy about OEM Glock frames is the thumb shelf/cut-out. It puts my thumb WAY too low on a draw and makes it harder than it should be to get a good high grip. I mean, you can nominally ignore it, but it's hard for me, at least. I never noticed it until I started doing serious training, and then it drove me insane. The P80 doesn't have it, which is a very good thing in my book. (I've heard that there are ways to deal with it on the OEM frame, and I'm getting desperate enough that I may be willing to try.)
I tried running my P80C with the new TBRCi stubby comp, and lo-and-behold, it didn't cycle _at all_. Like, failure-to-extract, stove-pipe, failure-to-feed, etc. The slide is clearly not getting enough juice to deal with the recoil spring, which I expected, but was still fascinating to see. I'll probably grab 12lb and 14lb recoil springs to see which one works best.

mpdc4511 thanks a ton for that.
They kind of removed the "Glock hump," too, didn't they?

I agree with Brad, 100%.
I'm a "read-aholic".
I read EVERYTHING I could, before I even took my first frame out of the box.
I used a cordless handheld drill.
Aligning the drill as level and plumb as possible on each hole, and stopped the drill as soon as the drill 'broke through' the frame material, through the jig.
I backed the drill bit out, without the drill running.
I firmly believe that with a drillpress, even if you shut it off as soon as you get through the frame material, that a spinning drill bit will open the holes up, more than needed or wanted.
There was a tiny bit of 'flashing' (sliver of polymer) on the inside of the frame, on a couple of holes.
They clean up really easy and clean with a sharp X-Acto knife.
IF you feel that you need to 'chase' one of the holes, slowly hand turn the drill bit in the hole with your fingers.
Sorry guys. I don't mean to sound like I'm an expert at this, but, I've drilled enough holes and screwed up enough stuff that this MAY help keep a frame 'usable'.

The reason they say not to use a drill press is because of how the Vice would hold the jig. The jig is designed to be clamped together like a clam shell, not clamped top to bottom.
They found when you clamp them top to bottom the hole locations were no longer correct, the jig was compressing and the frame moving around inside.

I feel that the undercut trigger guard gives me a more natural POA. More like a Sig, but not just like a Sig. Also, the Glock hump is gone.
And the 13lb recoil spring doesn't quite get my comp'd G19 back into battery after shooting. Fun times. Time to move to the 15lb spring... hopefully that's the sweet spot.
I swapped out my 18lb recoil spring with a 15lb one. Zero issues with bulk range 115gr ammo.
