I guess I’m building a Glock...

    A coworker and I have talked several times about me buying his 10mm witness and he seems like he wants to sell it but just can’t turn it loose. Today he told me that he had bought a polymer80 Glock kit and would be replacing the complete lower on his g20. So a quick back and forth exchange ended up with me agreeing to buy his complete lower, a couple mags and other small bits for a flat hundred bucks. Sooo... as much as I dislike the feel of a Glock, I guess I’m building a gen 3 g20. I want it to be affordable but also interesting and light, so slide cuts and a custom barrel are absolute musts. Where should I look for the slide? I think I already have settled on a barrel.

    Not sure I’d want extra holes and less weight on a 10mm slide but it’s your project. I’m not up on the Gucci Glock scene but I know Lone Wolf sells plain and milled slides in about every variant you can think of.

    Lone wolf is the maker I’m most interested in for a barrel right now because they seem to blend quality and price nicely. If I can get a LW slide and barrel reasonably then I’m happy. I might even go as far as buying a complete upper just to get it all together. Of course this is project gun #10 so it may take a year to get it together, or I may bump it up the list. I really want a 10mm and was considering a witness limited or witness elite. This gets me a more marketable gun in the same price range that is more easily customized and is known as a good gun.

    I had Lone Wolf barrels in a G19 and aG34. Very good barrels, especially in the G34.

    I was thinking the same thing. Are you planning on shooting the resulting gun with light loads?

    I can't see enough a weight savings in a custom slide to be worth it.
    A slide milled for optics is another story.

    I have a G20 gen4 and have left it 100% stock. It shoots anything I feed it including cheap 40 S&W ammo and up to the hottest Underwood ammo.
    I suppose it could be improved on, but in its stock form, it has been 100% reliable.
    BTW it is my every day carry.

    Your 10mn reliably handles .40 S&W?

    I vote for Lone Wolf barrel as well. May not be the cheapest barrel you can find, but I know they are quality. And I don't even shoot Glocks on purpose.

    I also might be roped into a Glock-ish project gun for a customer of mine as well. Mine is more interested in a G19 size and caliber. So I have been looking at Polymer80 builds as well.

    Yes. I shoot 40S&W in my G20 often with no problems.

    I actually know several people that shoot 40 in their Glock 10mm's.
    Not recommended in 10mm 1911s though, so I am told.

    I have built a number of polymer80 frame guns, and they fit my hand much better than the Glock. I love them. I have a glock 29 in 10mm and a witness stock in 10mm, so I was searching for a long time for a Glock 20 slide to build a glock 20 on a polymer80 frame. I could not find g20 slides anywhere for under 500 dollars. I ended up buying a glock oem 21 slide for $160 and an oem g21 barrel and then a g21 10mm conversion barrel from storm lake and an 18lb recoil spring from NDZ. I use the glock ejector but filed down some--you can google the topic. It's been totally reliable in 10mm and 45 acp, and I have two guns in one; I simply change the barrel, recoil spring, and magazine. I don't think it's a good idea to lighten the g20 slide.

    The g20 will grow on you. I'd just buy stock or near to stock you can get for the price, shoot and enjoy. They're great general handguns for just about anything that needs a good shootin'.

    I bought a lone wolf Glock barrel and it did not shoot any better than the factory barrel . I would recommend Bar Sto . Not cheap but worth every penny . On my 3rd Bar Sto barrel (3 different guns ) noticeable improvement every time .

    The Polymer 80 lowers have more of a 1911 grip angle than a Glock grip angle. A completed Polymer 80 lower with a couple of mags for $100 is a good price (if he did good work). It's looking like complete G20 uppers are gonna run you about ~$500. Now mind you, you can get a brand new Glock 20 for $550, so even at the discount you're getting, that G20 type pistol is gonna cost more than a new G20.

    Custom built 1911s will cost more than factory. The worthwhile expense is you are getting what you want instead of spending 550 on a new Glock and 300 on upgrades and changes.

    Check Brownells for slides. I couldn't find anywhere close to their price. May not have 10mm, but they have other stuff.

    Actually no. I very much dislike most things Glockbut I intend to change that by avoiding stock parts. I will end up being roughly same-money into the gun as buying new, but with a much better aftermarket barrel. From what I am seeing now, there is a good chance I can come in right at $500-550 total with a 6” threaded barrel with comp. cheaper still if I do a “featureless” slide or wait for an alphawolf to be available. If I do featureless I will mill the slide how I want it. Straight light cuts are simple if you take your time on layout and clamp. Rounding edges is also fairly simple so im not worried about finishing that out. AND I have a line on a used advantage arms 22 kit cheap enough to justify.

    I would not mind seeing the parts list with prices and where you got them from.

    Doing it all in AlphaWolf parts from Lone Wolf would only be $520 in parts in addition to the original $100 purchase. That includes no sights, but for what I would do with a featureless slide I would have it slick-topped anyways except for a cut to mount a fastfire3 or similar optic at the rear of the slide. Again, waiting for a sale on a barrel or a deal on a usedfactory slide would cut likely 50-75 off of that. From what I’m seeing, a 20 is roughly a $600 gun after shipping and transfer so right there I’m at $620 if I buy parts now, or 550 ish or less if I wait out a deal.

    OR even better if I buy the used g21 I saw today that’s cosmetically challenged for $325 after haggling (asking $359) and have a complete 45 then just buy barrel, mags, and recoil spring. The deals on used 45 guns are making me seriously consider dumping this one and buying a complete trade-in to build which would cost a touch more but would give me an extra caliber.

    The other thing that is holding me in consideration of building up this frame is doing a Glock 40 build. Long slide, long barrel, threaded, with comp. doesn’t add much in cost, but it adds a ton of weight to a gun that’s already a pig.

    Glocks are like AR's. You don't build one you assemble it.
