Thank you for that.....You may have provided the answer....Yes, while I have / had been learning to rack the slide on my G19, which was very hard for me at first. The mag was empty....Thus far, I have put any round in my Glock or mag,,,,I was just learning to rack the slide..I have a cocked left hand (Former broken wrist) and very fine (small wrists) So, thus far I have only been learning to properly rack the slide and handle the gun safely.....I can now pull the slide quite nicely. Especially as I mention, adding some practicing "trying" to rack my CW9 nicely...Which I am still working on and find much harder then my G19.....So, other than my practicing the ability to rack the G19's slide...So far neither the gun nor the mags have yet had a round in them.....From your reply, now that I can strongly pull the slide, it sounds like I am pulling back to the lock position because the mag is empty??? Maybe I should have been doing this with some dummy rounds in the Mag!!!! ...(Maybe??) Thank you!! --- Karen
