Tried the CZ 75 P01 and loved it so I just purchased one and joined the CZ Forum. Okay, any recommended upgrades, alterations, etc. that I should consider and why? I only thought about this subject when I noted one of the firearms for sale. The seller pointed out he had made several upgrades (see below). Frankly, I have no idea for the most part what these are so I thought I'd ask. In short, is the firearm perfect out of the box or, through experience, are there some things I should be considering having a gunsmith change?
Here is what the person did to his/her gun: "CGW reduced power trigger return spring, 13# hammer spring, reduced power firing pin block spring & firing pin spring, floating trigger pin, firing pin retaining pin, and I will include a reduced power recoil spring."
