The gun is one year old with approx 1,200-1,500 rounds through it. I put about 400 over the past two days. Out of the 8 mags I've set aside 4 that are giving me some issues but will be cleaning and inspecting all of them. For IDPA next week I may just use the new Wisom ETM that I have. Is there a break in period that I need to be aware of?
