Recommendation Glock 30S or Glock 20

[neomedic]

Hahha....I like how it went from buy both to now buy all 3!!!

I prefer the feel of the Gen 4 G20 over my G20SF and G29SF.

Having said that, I probably will pass on the Gen 4 G20. There have been far more reported problems when shooting hot ammo with the Gen 4 for 10mm Glocks (mostly all you ever see are the problems, so I am not saying they all have problems, but compared to the Gen 3 models, definitely more issues).

There is a very experienced 10mm reloader guy on the GT Forums who is convinced the Gen 4 frame flexes more and this is at the root of most of the hot ammo feed issues. He actually sent a letter to Glock outlining his theories.

On the idea of buying a G21 and using a 10mm barrel, again, not my first choice. The G21 slide in lighter than the G20, so slide velocity will go up with equal ammo. On the hot stuff it might again start causing issues.

So, all this brings us back to what to do? Maybe SSE the 30S and save for that G20SF (Gen 3) down the road, there won't be a rush for that one.

Why waste money on SSE a gen 4? Just get a gen 3 20sf.

^^^After shooting other glocks (17, 19, 21), I much prefer the Gen4 grip texture. It makes a huge difference in feel for me. And the larger magazine release is big bonus as well. I like the gen4 over gen3.

I guess some might say get it stippled or talon grips, but I if I like the gen4 grip as is so I figure might as well get gen4.

[neomedic]

What is considered to hot for the gen4 g20? Is it too hot for a good defensive ammo? Or are we talking about extremes and the upper limits of the 10mm?

Don't let the mag release deter you. Like you, I much prefer the gen 4 larger mag release. But for some reason on the big ol' gen 3 G20 SF, the mag release is a piece of cake to find and press. I can't stand gen 3 mag releases in general, but it's very good on the G20. Try it out in a store if you can find one.

I also agree on the better grip texture on the gen 4. But you could always stipple a gen 3 yourself to improve the grip.

I have to admit I wasn't aware of the gen 4's having hot ammo issues. I'll have to look into that.

I suspect they're talking about hard cast gas checked bear loads from Underwood and Buffalo Bore.

Damn..wish the G20 gen4 was flawless. Would of made my decision much simpler.

Generally, the problems I have seen posted were with VERY hot loads from companies like Underwood, Buffalo Bore or nuclear loads from reloaders.

For example, a 180gr GD Underwood round that will clock in over 1300fps out of a stock G20 barrel. It is ironic as you don't need anything near this hot to have a very hot SD round. In fact, at 1300fps you are over driving the Gold Dot bullet and will like have jacket separation, etc. XTP's at this speed will likely hold up better, but you are looking at 17-18" of penetration in calibrated ballistic gel (way more than plenty for the biggest "penetration" addict).

Realistically, 180gr going 1150fps will do everything you will likely need in SD ammo. If you are going fishing where real bears might be an issue and you want some backup (not that it is any guarantee), then 200-220gr WFNGC bullets running at nuclear levels might be what you want. But if you are going that far to fish, maybe hire a guide that owns a rifle with a big hole.

Good luck.

I wouldn't let it stop you. The only place I could find any problems with the Gen 4 G20 was on the 10mm-firearms board. There was also one problem here on Calguns.

Other than that, I can't seem to find any problems. And Glock took care of the guy that started the thread on 10mm-firearms. So I would say go for it.

No issues with underwood 200gr xtp in either of our stock glock 20's or the doubletap 200gr wfngc as well. Only had an issue with an aftermarket lone wolf barrel that needed a feed ramp polish, now all is good.

[mag360]

I fully agree with what bill steele posted. That man knows the 10mm well. For self defense in the 10mm it would be hard to neat the factory hornady 180gr round, the critical duty 10mm, or id wager the new federal trophy bonded but it has a lot more speed than you "need" along with the extra recoil. Unfortunately hornady does not case mouth or priner seal the "custom" loads. Only the critical duty and of course federal trophy bonded is sealed. For water protection.

[neomedic]

That's good hear. So only a few isolated incidents.

Not as much as the G17, G19 Brass to face issues and ejection issues. I consider that a real issues as it was pretty wide spread (even though people on forums keep pointing out that only people with problems report issues and there are more without issues). It's enough for me consider it a problem.

I might lean towards the G20 gen4 then. As much as I like the G30S, having a nice 10mm for outdoor activities and the ultimate HD is nice to have in the "collection."

Buy a Gen 4 G21 and get the .460 Rowland kit.

I just went through a similar scenario (G30S vs. Gen 4 G29). Then another CalGunner introduced .45 Super to me and it made the decision a no brainer - 10mm ballistics in a .45 ACP sized cartridge. G30S is what I chose.... Still waiting to DROS due to 1 in 30.
