Need to hear from some Glock experts.. I have a few tech/mod questions that I want to answer. Recently purchased a Glock 19 Gen 4 for the wife, she is a new handgun shooter and does fairly well with it, in fact she shoots it as well as she shot my 1911 (4” group at 25 yards) so I was able to get that back now that she has her own gun.

Purchased at the same time was a Glock 20 Gen 4 for me as I have wanted to get into the 10mm power range for quite some time, I got this for knocking around backcountry, bear country etc.. Not so much for self defense against 2 legged critters but as a potential hunting sidearm. I’ve been hunting with handguns since I was 18. I have shot just about every style of handgun out there from CZ and clones, BHP, 1911, S&W revolvers and semi-autos, ROA’s, XD’s, HK’s and Sigs..

What I shoot the best: MY ROA .45= 1.5” groups at 80 yards, Over 20 Whitetails to date.
My Dan Wesson .357= 3” groups at 100 yards, 17 Whitetails/Mulies and 2 Elks
My 1911 .45= 4” groups at 50 yards, 4 Whitetails, 8 Turkeys
My HK .40 = 5” group at 50 yards, 3 Whitetails
My Buckmark .22 = .5” at 25 yards, More Rabbits, Squirrels, and Grouse than I can count.

With the Glock 20 so far = 3” at 25 yards.

So here come the questions:
1) What aftermarket barrel should I get for her 19? I say this because I do reload and want the fully supported chamber without the little dimples on the brass and the ability to shoot my cast bullets. If at the same time I can get a little better accuracy then even better. I’ve looked into the Alpha Wolf threaded at 4.6”.. Suggest any alternatives?
2) Same question for the 20 for me.. 10mm ammo is really impossible to find over the counter anywhere around here so I’ve picked up the dies to reload it as well. The stock barrel seems to like the 200 gr. pills the best, but that may change with the new barrel. I’ve looked into the KKM 6” Match barrel in 10mm. Suggest any alternative’s?

The overall goal here is with practice to end up at a 5-6” group with the Glock 20 at 100 yards. I don’t think that is an unreasonable nor unattainable goal.

3) I’m getting a set of SlantPro Straight Eight Night Sights, I think they should help extend the range a bit to end up with some hunting accuracy and low light sight picture. The Glock sites leave a bit to be desired. Suggest any alternative’s?

I am also considering making up a Glock Pistol Pack on the Glock 20 by picking up extra barrels to shoot other calibers thru my 20 with the same Glock 20 Magazines.

4) That said I’m looking at another KKM barrel in .40 cal conversion standard length 4.6”. Also looking at the Lone wolf conversion barrel 9mm in 6”. Suggest any alternative’s?
5) And lastly I’m thinking a 3.5# connector for the trigger group. However, I Don’t know much about alternatives.. While I know I’ll never get say a 1911 style trigger, I can get used to another trigger if it will enhance the accuracy of the weapon or keep the same trigger and just change the connector. I don’t want to and won’t do anything for a better trigger that affects reliability.

So please limit the discussion to answering the questions if you can.. I’m not trying nor do I even really want a which is a better gun argument to erupt. Guns are tools and I’ll learn to use them as is or I’ll make the mods so that they are better if I can. So far I like our Glocks, I just want to do what I can to make them a little better.
 
KKM, Barsto, Briley, Wilson, just make sure you buy a gunsmith fit and not a drop in.

Wish I could find it again, but somewhere on Youtube, there is a guy with 50 lone wolf barrels for a 10mm (I believe). He tested after he had a kaboom with one. Not a single barrel had a correctly spec'd chamber. I personally wouldnt give 10 cents for Lone wolf anything. YMMV
 
Skip the barrel replacement to shoot lead reloads. Hardcast lead works fine in Glock barrels. Many reloaders here have shot thousands of properly sized hardcast lead bullets in their Glocks with no problems at all. Also consider plated bullets if the lead makes you nervous. Plated costs about the same as good hardcast bullets. If you want to shoot a different caliber then you need a good quality barrel.
 
Not sure how good it is but Glock offers 6" "Hunting barrel". They also offer adjustable rear sight which they put on competition long slide guns including "Hunting Glock" which they gave model number 40. I found the best ammo to be HPR 180gr JHPs.
 
KKM barrel for the 20 and the right load should get you close to your goal. I'm shooting 10.5 gr Blue Dot under a 180 XTP out of my G20 with the factory barrel and grouping 2 inches at 25 yards. No other load (factory or handload) has been able to duplicate that accuracy. Though I'm getting too old and blind to be as consistent as I used to be, others have gotten excellent results with that load. I'm not getting much of a bulge either.

With the KKM it gets slightly better with that load and shoots pretty tight with most any other loads. I like the KKM and it is my preference having shot a few of the others--LW, Barsto, Federal, Briley...

Have you looked at the new Glock 40?

My G17 shoots fine with the factory barrel with most loads. The KKM barrel for it measures about .002" tighter chamber measured at the halfway point and seems to shoot a little tighter. It does like the WWB 147gr hp a bit better than factory. No bulge with either barrel.

The wife's G19 stays in OEM configuration, thank you.

Good Luck

Thanks for the suggestions guy's keep em coming.. I looked at the Glock 6 " hunting barrel but it still said polygonal rifling. There is no saying that I will settle on a cast lead loading but Right now the 20 shoots BB LRFN and HPR XTP 200 gr.. the best..

The wifes 19 likes 147 Gr. Noslers the best so far, Followed by BB 147 LRFN..

Has anyone ever tried putting a heat sink inside the barrels on a glock and then welding a bead around the end to then hand fit it to the slide? I've done that to a couple 1911's and got excellent results all but once.. Ouch....
 
I recommend NOT getting a lone wolf barrel. I tried a 6 inch one in my G20 a while back. It would not feed factory ammo. I think they're made in Korea. Plus their customer service is not good either.

Why not coated bullets? Cheaper than plated, no barrel leading or smoke from bullet lube.

Win...win. [emoji6]

1. You may not need an aftermarket barrel. Measure your chamber and look hard at your casings. My Gen 4 Glock 19 has a nice, tight chamber. My casings don't have the smiles or anything like that. If you get an aftermarket barrel, I second the above suggestions. Lone Wolf is a joke, but I've had great experience with KKM and Barsto.
3. Heinie sights are great, but look closely at the sight heights available, and their POA changes based on load and range such. It's a sensitive science and you might end up changing out your front sight a lot. For that reason, you might want to look into an adjustable set. I like Dawson Precision personally. The competitive shooters mostly seem to like black tears and fiber optic fronts. That's become my favorite combination. Sight widths and heights are a whole new world though, so prepare to read a lot.
4. My KKM 40-9 was fantastic.
5. The 3.5# connectors will be effective in lightening your trigger on the cheap. It's not going to change the feel, just the weight. As well, I very highly recommend lightly polishing all wearing surfaces in the trigger mechanism. Just don't remove any material. If you're not satisfied after that, there are some really nice drop in trigger options. I don't know much about those.

Edit: Oh yeah, and definitely look into powder coating your bullets. It my change your life.
 
I don’t want to and won’t do anything for a better trigger that affects reliability.

most of the aftermarket triggers wont effect reliability unless you start messing with the striker springs. I exclusively run Vanek triggers in all my Glocks. Vast improvement over stock..
 
Powder coated bullets for everything has High potential.. My Nephew already does my .357 bullets for me like that with great results. May give him a bunch after I settle on some loads.

KKM barrels seem to be the overall favorite so I'm guessing that's what I'll order.

Trigger work on the cheap a Ghost 3.5 connector or a Glock (-) connector... May try them first and then look into Vanek.
 
Another vote for KKM. Good accuracy and easy to clean. I've also shot pretty hot 10mm through it and no brass bulges either
 
I've had good luck with my cheapo Lone Wolf in my G19. Home cast 125 grainers shoot fine. I size a little over recommended. Zero leading, zero malfunctions and it shoots better than I can. YMMV I guess.
 
I would leave the Wife's 19 alone. Give it plated or coated bullets, don't overload them to where you get "dimples" and she will be in fine shape.

Shooters hereabouts consider the KKM to be the class act in aftermarket barrels.
 
Weird, haven't had any issues with LW in my G20.4 - Feeding, case support, and accuracy are all quite good.
 
If your at all handy a after market trigger is not needed. My Glocks have reliable 2 1/2lb triggers using a 3.5 connector, lightened firing pin spring, lightened firing pin & a further stretched trigger return spring (this also eliminates the take up).
