I love 10mm.
If anyone is really serious about bangin 10mm hard as hell, the Glock 20 can take it all day long.
NO OTHER 10MM HANDGUN:
1. Have a variety of aftermarket match grade barrels for target shooting or hunting from stock length to 6".
Here is what I rock during deer and hog hunting:
2. If you like to reload, you can rock some serious hot 10mm Norma loads in your aftermarket barrel and have the polymer frame take up the snap.
3. You can get conversion barrels to rock 357 sig, 40cal, and 10mm out of the Glock 20 platform.
4. A great amount of aftermarket accessories: Several choices of adjustable target and night sights, lots of holster choices, cheap factory mags, etc.
And yeah, the trigger is different but my targets with 2" groups at 50 yards offhand tell me it's a great 10mm gun. A good CGA can polsih your firing pin channel, your firing pin, lighten the firing pin spring a touch, polish your trigger bar connector and drop a 3.5# connector in there and it's a very different trigger than a stock Glock. Straight up - and I rock 1911s with slicked up trigger too.
It's all in your time behind that trigger.
You can't do any of the above with most if not any of the other 10mm handguns. Maybe another expensive barrel but that's it.
With the G20 unit, you have options - like the AR-15 in the carbine world - where is my grenade launcher honey?
Love my SW 610 revolver though
