Yer, you can get every bit as high a grip with a safety model as a decocker. That shouldn't factor into your decision. You also shouldn't factor in your concerns over manually decocking one. The simple fact that you are concerned about it takes you out of the running for someone who is going to blow it. I just Frog-lubed my thumb and did it over and over. It's not difficult. It's not iffy. If I can do it one-handed with my thumb lubed, you can do it with a little sweat out at the range. I understand your concern. You feel like when you pull the trigger, the hammer will suddenly exert force and might slip from your thumb if you're not holding it right, but that's not how you do it in practice. In practice you pull back the hammer with your thumb first, then pull the trigger, then let the hammer down. There's no sudden force against your thumb because your thumb is already fully supporting the hammer when you pull the trigger. If you pay attention to what you're doing, you're not going to blow it. NOW...
... just get the right gun to start with and save some time and money.
The above quote is key. If you want to compete, you should receive a gun with a good trigger. If you want one with an FPB, get one, and if you want one with a decocker, knock yourself out, but get it WITH a decent trigger. This means you buy a Shadow, or you buy an SP-01 Tactical from a custom shop and have them work the trigger over before they send it to you. The stock 75/SP-01 trigger sucks. I'm not saying you have to get every single custom option you want up front, but at least a trigger job with a race hammer. And since the hammer is an external modification, make sure whatever hammer you get qualifies as an OEM part so that your gun isn't disqualified from Production/SSP.
The extra $260 for a Shadow or $250-$500 for some gunsmithing up front will make you happier in the long run. I promise.
