i also have a M1, some beretta shotgun, ruger mkII, and a bunch of other guns i don't shoot. also i realized in my first post that i said i have a 229 and 220. this is false. i have a 226 and 220. whatever.. 9mm and .45 is all i know. i put whatever rounds in that fit and clean it religiously, don't know much else about them.
i consider myself a good shot with a pistol though.. i shoot [at] playing cards at over 50 yard [and usually hit them]. though there isn't a place in my house that is open for 50yds, so that can't matter much.
rule number 4: the double-tap.
