I recently got my first 1911; a Rock Island Armory Tactical Two-Tone. I love it, but have been reading up on 1911s in general. I've heard you shouldn't drop the slide on an empty chamber, is this true? I haven't done it since I read not too, but I've done it about 10 times since I got the pistol brand new; you reckon anything is messed up? I've also dry fired it around the same; maybe 10-15 times. Is it ok to dry-fire a 1911 like you can a Glock? I know; two different animals. I'm used to Glocks and other polymer pistols, so this is new territory to me; I will say that I'd like to get a higher end 1911 some day; I like the look and history of the 1911 design. Thanks for any and all help!
