I've had my LCP for a couple of weeks and have put about 100 rounds through it on two separate occasions - 50 rounds per session. Towards of each of the session I've encoutered a "stove pipe" issue. Is this typical for a break in period? Could this be the sign of some wrist fatigue? How many rounds do I put through this pistol before I conclude it's ready to be carried for personal protection? I would love some advice on this.
