I have both a Glock Model 19 in 9mm and a Ruger SP-101 in .357 Magnum. They are of similar size and weight, but I lean toward the Glock due to the 15 round capacity vs. 5 rounds in the SP-101. It is also quicker to reload. Love the Glock, reliable, durable, don't shoot lead bullets or super hot loads to avoid kabooms, and it will serve well.
