How did they feed with the Lone Wolf barrel?

LW barrel is gone, they sent it back to me after testing that there is nothing wrong with it and I sold it.

I will try the heavier RSA today as a test but not real confident in this g20 anymore.

There was a guy on Glocktalk, his handle was 3/4Flap, who had a problem with a G20 similar to your Gen 4. The rounds were misfeeding to the left like in your picture. I don't know if his posts are still there, or if Eric purged them out. It's interesting though.

He ended up getting a replacement gun from Glock, in a different caliber though.

Best of luck to you with your gun issues. I am sure you will get it worked out somehow.

Just got back from trying the heavier spring set up and it made things worse, I guess its time to move on.

Very same thing but now its jams with the DT 200 which ran fine the the factory RSA

So now it's sounding more like a magazine issue.

That's funny because I was just looking at them ${$default_grin_smiley}$

DA/SA or Single action only?

The Hunter is a great SA only 6". If you want the shorter 4.5" barrel DA/SA get a Stock II. In the 4.75" SA only size, it's hard to beat a Match, although the Limited is the bees knees. Don't forget the Limited Pro as that's the 4.75" DA/SA version with no rail and shortened dust cover... basically between the Match and Limited.

Stock II

Are they ok to shot HOT ammo out of ? I have seen a few posts online that they are not rated for +p ammo

Intercooler · January 26 2014 09:23:03 AM MST

That's some EAA stuff they put out there. With just a $8.00 20-22lb spring you are good to go shooting the nastiest stuff out there. While doing the swap though put a $25.00 Henning flat bottom firing pin retaining block and a $35.00 Henning Cone-Fit guide rod in there to help it last a long long time. We have StockIIBoss on here that owns one and could give more information about it.

I have a 22# Wolf spring and a LWD steel guide rod/Gen4 adapter bushing I run in a Gen4 g20. It won't run 135g Underwood. You can feel the slide slam at the end if its travel and when it does, the impulse twists the pistol upward. I suppose I could tighten the grip and wrist beyond normal, but the same ammo runs fine with the stock dual gen 4 spring.

That dual spring seems to be a decent idea. It also appears the aftermarket (or Glock) would be wise to build heavier copies of the same idea. I wish I'd have gone with the 24# with the setup, but a 28-30# setup might be what's needed for running the big heavy stuff with a single spring. As it stands now, it seems the aftermarket support simply just isn't there for the Gen4.

Cash flow is a bit of an issue right now, but the Limited Pro seems like an excellent idea.

Hey all. I heard my cage rattling! ${$default_cheesy_smiley}$ Yes, I have the Stock II and couldn't be happier with it. As for shooting full loads like Underwood, I've had zero problems. They're built like a tank, and that coned barrel is massive. Yeah, they're more $ than a Glock, but you have to pay for all that 'awesomeness' going on... ${$default_smiley_smiley}$ I have tweaked mine a bit, but that wasn't to resolve existing problems. More of a 'to suit' kinda thing, such as a trigger job, fluff n buff, coned guide rod, various recoil springs, etc. On mine I had no issues with slide battering, but followed the advice on here to go with the Henning coned guide rod and heavier spring for some insurance. Works great, just like before, but if it can help save a little beating, I'm all for it. I finally settled on an 18 lb spring. I've had no problems mechanically with the various spring weights, either with Underwood or the weaker offerings out there (Armscor, etc). Everything feeds and extracts/ejects just fine. I don't recall ever seeing a +P option for it. Of course, they shoot like they're "hot" loads! But that's just what the 10mm is supposed to feel like. Yes!

Tanfo prices are creeping up. Figures, right?

mt10mm · January 27 2014 08:25:16 PM MST

I do like them but they are getting up there in price. I am going to keep my eyes open for one local.

IC,

You have ammo inbound, should be there Thursday.

Intercooler · January 28 2014 03:30:14 PM MST

Cool. I'm doing a bunch of 9mm Saturday and will do those 10's with them.
