Do I want a 20 or a 21?

DrtyHarry · 02-09-2010, 17:53

It's about time I picked up another Glock, this will be my third as I have a 17 and a 27.

Looking for a large cal., more for the woods as well as HD/range. Maybe some hunting after adding a longer barrel. I think 10mm is the way to go here.

I started toying with the 10mm cartridge and am really liking it. Got to plink my buddy's Delta not long ago and I was blown away by it's accuracy and power downrange. Anyway, I'm a 1911 guy, most of my guns are 1911s so I am rather familiar with the .45 ACP cartridge. So, in a way I do want something new and different.

I will primarily be shooting 10mm, my understanding is that I can buy a G21sf and drop in a 10mm conversion barrel. I see KKM makes a barrel for this application. My question is reliability. How reliable are those "drop in" conversion barrels? Would you trust these barrels for HD?

If I'm going to be shooting .45, I'll more than likely be using one of my 1911s. The 20 is $50 cheaper than the 21 in my neck of the woods (can't find a 20sf RTF2 though).

I saw pics of a 21sf RTF2, did they start making 20sfs with the RT2 frame yet? Not sure what way to go...20 or 21.

20 ONLY if you reload, in my opinion.

20.

10mm ammo is pretty damn expensive, but you can offset the costs if you reload. I was ready to pull the trigger on a 20 til I checked out ammo prices and availability.

I'm going to start learning how to roll my own soon enough.

My buddy rolls his own and hooks me up.

The slide on the 20 is heavier. It's better suited for hot loads.

up1911fan · 02-09-2010, 18:03

You definately want a G20SF, or wait, maybe that's me.

Hmm. I buy my ammo (9mm and 10mm) from DoubleTap. About 40.00 box of 50 or 385.00 for case of 500. Always in stock ... and can't imagine wanting to load my 10 any hotter than DT does. The probably won't find a better round for "the woods" than his 200/230g hardcast. Tax free unless you live in UT.

I suppose for low(er) cost practice ammo (which I don't generally buy/use) this might be a concern though.

I have read some grumbling about DT lately though ... not sure what that is all about.

I own the G20, and have never tried to convert a 21 to 10MM, but I do have an opinion about it. The extractor and breech face are not exactly right in the G21 for shooting 10MM even if you do change the barrel. I realize that people are doing it and it seems to work, but I'm still suspicious enough to say I'd limit the idea to a range or hunting gun, and wouldn't bet much that it will prove reliable enough for HD.

Then again, you may do it and find that it never ever jams, proving me totally wrong. If you decide to risk the money on the experiment, please post here as to the reliability of the combination. I'd really like to know.

Just buy a chronograph (For the price of about two and a half boxes of DT ammo - not worth not having one.) and you'll see almost instantly what most of the grumbling is all about.

Interesting. I haven't bought any ammo since mid-last year (bought a couple cases then).

What are the specifics and when did they start ... or is this a taboo subject on GT (is DT a sponser)?

20 to a 21 but not a 21 to a 20 is what I understand. Get the 20sf and reload. I do not think converting the 21 to a 20 is a good idea IMO. Leave the 45acp to your 1911's or get the 21 and be like me. I have a Kimber 1911 and a G21. I do not have any other calibers besides 9mm and 45acp. I like other calibers but stick to the basics in my pistols.

Just buy .40 cal. I heard you can shoot them in the 10 mm guns.

DEADLYACCURATE · 02-09-2010, 19:17

Get a 20 and reload

You can also shoot .357 Sig in .40 and 10mm but I'm not gonna do it

MatGlock · 02-09-2010, 19:20

I've got both. Get the G20.

DrtyHarry · 02-09-2010, 19:36

G20 it is. Too many variables to go to 21 to 20.

Only question I have is if Glock started making RTF2s for the 20sf. Anyone? Thanks again all!

oISHUTupNrocKIo · 02-09-2010, 19:39

If your a 1911 guy, leave the .45 ACP for the 1911s then... the Glock 20 is the most powerful Glock and hell of a time shooting at the range and the perfect HD weapon IMO.

Max1775 · 02-09-2010, 19:41

If you want something powerful and different than .45, then 10mm is the way to go. Personally I love the .45 for the power, availability of ammunition, and cost... Having said that, I wouldn't mind a 10mm, especially for hunting.
