Nice choice, I LOVE mine. Can't seem to get a foldable charging handle though, Ive been trying since april. Weigh down your EP9 with sight, optic and a light, it needs the weight because it's so light. Makes it much better to shoot. I also have a full 32 round mad attached to the side of the brace, with velcro straps. See my avatar for my setup. I tried to convince myself to buy a more expensive 9 pcc, but the only one that shoots better is a Sig MPX. It's more durable due to less polymer, but it's 4 times the cost. Ive shot scorpions, EP9 has far better trigger, and better recoil. I did get the $16 JP spring kit, not sure it did anything.
