The TM 226 safety completely blocks from firing. It doesn't just make pulling the trigger harder. If that's what your gun does, then there's something wrong with it.
And with the strong double action trigger on the P226, there's no need for a safety. If it's decocked, you can't set that thing off except if you deliberately pull the trigger. And the idea is to be able to draw your pistol, disengage the safety, and fire ASAP. Unless you're left-handed, that's impossible to do with the 226 if the safety is on. And even for a left-handed shooter, that's awkward.
