Last year I bought a CZ Scorpion Evo 3 9mm Pistol. Nice, large, handgun. Earlier this year I bought a Palmetto State Armory PA-9 9mm pistol with a Shockwave Blade Arm Rest. I liked the arm rest so much I ordered one and put it on my Scorpion. Using the Sig Sauer Romeo-5 Red Dot sight on the Scorpion I dialed it in for this result: I think I'll keep it like it is!
