RE: glock ???
I once went to the range with a bunch of Glocks - a model 27, 23, 22, and 34. Stuffed a 15 round magazine into each one. Laid them out on the picnic table. It was a good comparison. As the guns get smaller, the amount of muzzle jump between shots increases. At the end of about 100 rounds, I decided to purchase the 23 instead of the 27. Roskoe
