which glock to get for 10mm.....20 or 21?

ive decided i want a 10mm glock woods gun, but im not sure of the route to go (theres a gunshow tomorrow so ill be buying soon). Ive done some searches on this but most of them are old so ideas might have changed. Should i look for a g20, or would it make more sense to pick up a g21 and then get one of the conversion barrels for 10mm (i already shoot 45acp so its not a problem in that respect). Just curious about reliability of a conversion, but i also hear 10mm is going higher and higher so it would be nice to practice with 45 then change over when im going bowhunting or something. Any experiences or ideas welcomed.

To me a woods gun is the same as a SD gun, if a wild dog (or anything else) attacks it needs to be drop dead reliable.

I'd rather have a 10mm with me for a woods gun than a .45, and I would feel confident with a conversion barrel.

Some people have had 100% reliability with various convrsions.

I'd get the 45 and convert it to 10... as much for all the OTHER conversions available as for the 10. If you don't care about those other conversions, go with the 20.
Fact is, if ammo cost is a concern, it's time to start thinking very seriously about reloading.

If you want a 10mm, get the G-20. The slide is actually heavier than the G-21. The 10mm is really a reloader's cartridge unless you have the funds to dish out major $$ for ammo.

Get the G-20. I'm not a fan of conversion guns. Some are reliable, some not, but most end up being used in one of the chamberings 90% of the time anyway. You already have 45, so why bother and go to the extra expense.

i dont reload but i definitely want the 10mm for bears (we just have black bears here). Does the heavier slide mean that much more? If i went the conversion route id probably shoot it mostly in 45 form, shoot it enough in 10mm to be comfortable and know its reliable, but rarely shoot it in its 10mm form. Are there any other fullsized glocks that convert to 10? i know the 29 and 30 do but i wont ever carry this gun concealed so im more interested in the larger version.

Get the G20 or G20SF to shoot 10mm then buy an aftermarket LWD 10-40 barrel so you can shoot cheaper and more available .40 S&W ammo. Shooting .40 S&W is less expensive that .45 ACP as well. Use only G20 magazines.......

^ My review of my G21 conversion. That's the route I'd go. It really is two guns in one. If you want to shoot full power loads you'll probably have to change out your recoil spring anyway; that puts you 1/4 the way to a full conversion!

If you really want a 10mm, just buy the G20. The G20 has a heavier slide and IMO a converted G21 is never as good as a stock G20.

I would and did get a 20. Although some have good luck, a conversion will never be as reliable as a stock gun. The cost of 10mm is not substantially more than .45. BVAC is around $18 to $20 a box, and defense loads are similar in cost for the two. I love having my G20sf along for the rise in the woods.

changes

I'm thinking you'd need to change the extractor too, and the mainspring. If that's the case, that's more converting than I want to do. I'd reather get a .40 barrel and drop in the G20 and shoot .40, than all those changes to shoot .45.

The 10mm is more cartridge than the .45, and if power is the issue the 10mm is the winner. The G20 holds a few more beans also.

There are extensive and lengthy threads on "Glocktalk" about the 21 45acp to 10mm conversion. The conclusions are all the same. Except for a small weight difference, the guns are the same and the conversions have all been very successful. There is even a long thread about the stock G20 barrel being used in a G21, with no difficulties. I had thought about the same thing and I decided, after a lot of reading, to get a "fully supported" aftermarket 45acp barrel and load my 21 with 45 Super. The ballistics between 10mm and 45Super are really close. Just take a look at Buffalo Bore's website and compare the two rounds. I chose 45 Super, for the obvious reason; it is a 45 caliber bullet.

the FBI didn't like it because it is hard on the gun and the shooter+ the rounds are pricy
