Glock 34 and coated bullets and upgrades questions

[kmaultsby]

Hello all, I have just shot my first IDPA match with a Glock 34 I mostly shoot XD'S but this my first with a 34.  I added a Zev competition spring kit and a Wolf barrel.  The only reason I added the Wolf barrel is because I am using coated bullets.  Is my question does the stock factory barrel work with coated bullets?   

[Beef15]

Three different commercial coated brands and my own have all worked fine for many thousands of rounds in my G17s' factory barrels.

Stock barrel is fine with coated.

Thanks.

Glock barrels work with everything.

Including lead. You just have to be diligent about cleaning the barrel on a regular schedule.

So it depends on the type of coating. Have you seen the blue bullets, it has a thick polymer coating, basically a polymer jacket. Those are totally fine, you’ll have no issues with the stock barrel. But the hi tek coating that a lot of people are making these days are kind of ifffy imo. They’re still really dirty in my guns. I wouldn’t trust them. I had a kaboom with lead in a Glock. Gun was fine, except the mag release and the mag. I was shooting a mix of coated lead and regular cast lead. So I been weary ever since then. But my guy who makes the hi tek bullets says he’s been shooting them in glocks for ever. So imo it depends on how thick the coating is.

You are 100% correct Sir!

Other than Blues I think fit matters more than thickness.

 

I get tolerable fouling at .356, and really none at .357 with Hi Tek. Lubed lead runs fine at .358. Larger diameter bullets will increase gauge or chambering failures, especially with import brass.

 

I clean somewhere between 2k and 6k when the action pieces start getting so carboned I can't stand it.

I might have to try .357 then. I usually get the .356 in hi tek coating. I really like them cause they’re cheaper then the blue bullets and they shoot well. I get the hi tek for .55 cents, compared to the blue bullets at about .75. Really pretty minuscule difference. But it adds up over time. 

 

The blue bullets are great though IMO. And they’re made right in the town I live in. Might have to go stop in and see how many id have to buy to get them for closer to 5 cents a piece.

I shoot blue bullets out of my G22 with a factory barrel and it works just fine and produces 6” groups at 40yds

[pskys2]

Bayou and Acme also seem to have a good coatings.

[dapribek]

Precision Bullets are terrific, I’ve shot them for years through 4 different Glocks. 

[Jamese35]

I've put 15k trough my 34 this last summer with no isues. I run bayou bullets.

[bulldog009]

I used to run Bayou's through my 34 factory barrel before I switched to a Storm Lake barrel. I never seemed to have any issues. Since switching to a 2011, I've switched to Blue Bullets, and I've run some of my 2011 loads through my Glock 17 MOS and it seems to do just fine as long as I'm diligent about cleaning it after. The coating on the Blue Bullets seems to hold up pretty well, they recently switched to a coating more like Bayou's, so it doesn't turn your fingers blue when your're loading, and you can hit it with a hammer and it won't flake off.

I've well over 150K of Bayou HiTeks thru several OEM Glock 17s. They do not lead at all because I've recovered fired bullets and are of the same weight as loaded, and no scratches. If your gun runs dirty on Bayous then it's the powder. 

 

Jfitz, blowing out a mag and mag button is not a KaBoom. That's just a case rupture, could be caused by anything but most likely bullet setback. Kabooms split t he barrel, crack the slide and blow the frame to bits.   Even .030" of setback can double the pressure. Article by Speer.

That’s exacrly what happened, the case ruptured. My hands stung like crazy for about 2 hours after. I’ve never been able to say for sure what caused it. For all I know I picked up a piece of brass that somone had discarded after 20 reloads and the case blew. Bullet setback is definitely a possibility. I just remberred I’d had been shooting hi tek coated for a while without issue. That day I was shooting cast lead with no coating and it happened. I’ll probably never  know for sure

I have shot blue bullets exclusively through my 34 and the stock barrel stills looks brand new other than the exterior finish wear.

Have thousands of rounds of the 200g blue bullets through my Glock 35 stock barrel with no problems 

[pskys2]

Even in gen 4 barrels jacketed bullets are more accurate for me.  Not a lot of difference at 25 yds but just finished some 50 yard testing and quite a bit difference from 8" down w/ 124 coated to 7" w/145 coated to 4" with 124 jhp at 50 yds.

Still don't see any pressure/leading issues though.

[Mac_Menamy]

I personally have had absolutely zero issues with factory barrels and coated bullets. I have not had any bad experience as far as accuracy, malfunctions or anything. I personally see no need to waste money on an aftermarket barrel, but that is just me. 

[HCH]

I’ve put lots of lead through a glocks, coated or lubed. Never had a problem.

I've put lots of lead through mine too.  Just clean them good after each outing.  No issues.

Glocks hit the market in the late 80s,gun forums hit the internet in the late 90s and informed shooters that lead bullets in Glocks were bad.That was big news to shooters that had been using lead bullets in their Glocks for 10 years.[emoji23]
