I have Nightguard 315. For personal defense I bought some Magtec 125gr +p ammo. It fits so loosely in the cylinder that if I point the gun upwards the bullets will actually fall backwards in the gap between the cylinder and the frame. I have never fire the weapon with this ammo but the inexpensive rounds I use at the range do fit more snuggly. I am just wondering if this will hinder the rotation of the cylinder should I ever need to use the weapon. I am a fairly new shooter. Thanks.
