Hi! I've been doing some Internet research for a while now on which first pistol to get, uses will be range duty first and then when proficient, home defense. It seems like the 10mm offers the best of all worlds as far as power, range, accuracy, modularity (can swap different barrels easily but not the other way around for pistols based on lesser calibers). My question is, how realistic is it to expect me, as someone who's never shot a real gun before (.22 rifle a few times about 20 years ago), to be able handle even the light 10mm loads (to practice with)? If 10mm is too much to learn with, should I still go with something like the Glock 20SF and then just right away buy an "easier" caliber barrel to start learning with? Wanna kill these ads? We can help!
