Out of the G21,G19,G17 what would be the best one for home defense? These are the Glocks that i am considering to buy.
+1. Shoot them at the range (most will have Glock rentals) and see which one you feel comfortable shooting the tightest shot groups the fastest.swinokur said:which one do you shoot best? That's the question.

Cartridge pressure does not necessarily equate to sound pressure - http://www.freehearingtest.com/hia_gunfirenoise.shtmlHowever, for HD only, I have an affinity for a low pressure cartridge like .45 ACP to hopefully save some of my hearing. If you've ever touched off a high pressure round indoors you know what I mean.
Besides just personal preference one would have to give the .45 caliber a slight preference as there is a smaller chance (being sub sonic) of this bullet going through walls creating collateral damage.
That's interesting because, after passing through either wallboard or plywood Winchester's 124gr 9mm +P and +P+ loads penetrate less ballistic gelatin than any of their 230gr 45 ACP loads under the same tests. Even more interesting is that their subsonic 147gr 9mm loadings had more penetration than any of the 45 ACP or other 9mm loadings. Ref - http://winchesterle.com/SiteCollectionDocuments/pdf/Handgun Bullet Barrier Testing Protocol.pdf. The study of ballistics involves far more than simple velocity. Without factoring in things like BC, SD, and bullet construction you can't even begin to make worthwhile predictions before doing actual testing.i would go with the 21. less penatration then the 9mm.
