Well, I took my new PPS43 to the range today. The only ammo I had was some Norinco and some Seller Bellot. Well, I loaded a mag with 5 rounds of Norinco. First shot, no problem, second shot fires the second and the third round. Third shot/ fourth round, no problem. Fourth shot/ fifth round no problem. Load up a second mag with another five rounds of Norinco and the same thing happens. So, I drop the mag and clear the fourth round from the chamber. The fourth round has a hit from the firing pin, but it wasn't hard enough to fire the round. So I decide to switch to the Seller Bellot. I load three rounds in the mag, walk up to the line, insert the mag, rack the bolt, and all three rounds fire without me pulling the trigger. Luckily I had the muzzle pointed at the backstop. Seems to me the firing pin spring isn't strong enough. Looks like I'll be calling MGS in the morning. I wish I would of had some surplus, but the tin I ordered didn't come in yet.
Here's a pic of the round that chambered, but didn't fire.
