Hey guys, just joined. I bought a G19 gen 4 on the 25th. I can't get out to shoot it for a week sadly. But I was wondering what if anything I can/need to do for a break in period. Also if there is any must have tool for cleaning and maintenance. I do have a cleaning kit, but any like all in one tool. The plastic tool I got with it for the interchangeable back strap came broken. So I need to replace that. Also taking my safety class in a few weeks so that must have is covered too lol.
