Took my 19 out the range and put about 200 rounds through it on Saturday. Everything seemed to run smooth but I have a question about proper functioning... Situation is... Shoot the magazine dry, slide catch works fine and I get a last shot hold open. I slap in a fresh loaded magazine, and the slide automatically releases and chambers a round. This only happens with loaded mags, not empties. I was under the impression that I should have to either hit the slide release lever, or manually cycle the slide to go into battery. I'm sure I'm not accidentally hitting the slide release when loading the mag. So, pardon my ignorance, but is it proper function for the loading of a full magazine to automatically release the slide catch?
