Y00PER, congrats on your G-20, hope it brings you all the best the 10mm has to offer! ${$default_grin_smiley}$

Thanks! I've wanted one for a loooooong time (15+ yrs), but kept blowing my money on other guns that were too good (price wise) to pass up.

Congrats to Sean from Vt and the other new G20 owners.

New member here, also a new owner of a Gen 4 G20. I appreciate 4949shooter's advice on getting the Glockmeister 24 lb RSA. Ordered one same day that I ordered some Underwood ammo. So far I've only shot mild factory loads (HPR 180gr FMJ), all good with the gun so far.

Enjoy your Gen 4 Gunbug! ${$default_cool_smiley}$

Let us know how it handles the Underwood..

Thanks 49, sure thing. I'll report in a week or so.

The Underwood ammo didn't arrive yet, but the 24-lb recoil spring assembly did. I'm glad to report that the HPR 180gr FMJ (pretty mild, around 1100 fps I think) cycles 100% with the heavier recoil spring. Now to see how it works with the full-power Underwood.

Can't wait to get my hands on a new Glock 40. Also considering a a G20 gen 4.

Also recently picked up a Gen 4 G20. It is all stock. I ran 200 Underwood 180 gr XTPs through it just fine. The trigger may be a bit stiffer than my 26 and 19, unless I was imagining that. Since it functioned well, I may stick with the stock spring. It was throwing brass a bit far. I really need to reload for mid-level loads and keep the Underwood for protection in the woods. Fun gun and pretty accurate.

The trigger on my Gen 4 was stiff also in the beginning. It should work itself out after 500 rounds or so.

I agree. It smoothed out noticeably after the first several hundred rounds. A 25-cent trigger job is also very useful if you want to knock off the bigger stuff early on. It makes a world of difference right away.

Finally got the chance to shoot the G20 with full power Underwood loads. Mostly good with the stock recoil spring and also with an aftermarket Glockmeister 24 lb spring, which was suggested to me in case the stock spring hiccupped on the strong non-JHP loads (which it doesn't). LOVE the gun. With night sights on it now I feel like it can be a trusty companion for all outdoor excursions.

One less than joyous thing to report -- Underwood 180gr Gold Dot JHPs don't feed consistently. It appears the hollow point cavity is so large as to cause feeding problems. I think other JHP bullet designs with smaller cavities in the bullet nose would not cause this problem.

How can the bolded be true at the same time? If it doesn't feed the Underwood consistently, why would you consider that "all good"? Does your feeding problem look like my OP in this thread? http://10mm-firearms.com/10mm-semi-auto-handguns/g20-gen4-ftf-issues/

Yes, I was inconsistent, obviously. All good EXCEPT for the wide-mouth (180gr Gold Dot) JHPs.

The 24-lb recoil spring didn't help with those JHPs.

Full-power FMJs fed 100%.

The increased weight RSA won't necessarily help feeding issues, if it is a feed ramp / HP issue.

Yes, this is what I was thinking. I'm familiar with JHP feeding issues from other semi-auto handguns. The wide-mouth JHPs like some of the Gold Dots are particularly susceptible to causing feeding issues.

And don't worry that I'm thinking your recommendation on the 24-lb spring was bad in any way.

I am slow to jump to conclusions or freak out when I have a bit of trouble with a new gun. Everything has a logical explanation. Eventually I, or Glock, or someone else will figure out how to get these Gen 4's (actually I'm only concerned about my Gen 4 but I'll share all I learn with other owners) to function with a wider range of power and bullet types. Not worried about it, just sharing and gathering data.
