Just curious but why can't you retrofit a P30 with a safety? The P30s' already have the decocker on the thumb area so it's not as if you would effect that function.
This is just what I have heard on here. Something about the parts not aligning correctly. If someone has both and would be willing to try, I would love to see the results though.
The slide release lever on the P30 is longer than the one on the P30S. So is the cut on the P30 frame to fit the longer slide release lever. My guess is that if you were to retrofit the safety lever onto the P30, there wouldn't be enough room for the long slide release lever + safety lever. However, would it work if you swapped the longer slide release lever with the shorter one (like on the real P30S)? I don't know if anyone has tried this, but the consensus is that it is impossible or not worth the effort. It'd be easier just to buy the P30S.
Besides the frame/part differences, I think price and part availability would prove it's not worth the cost and/or effort. The shorter slide release lever + right slide release lever cost around $56, plus you'll need a new safety lever + hammer axle + detent plate + slide plate + slide plate compression spring (if available).
HKparts.net... Adam and his staff are great and will walk you help you with all your questions. Adam even spent time on the phone with me to talk about his preference between DA/SA and LEM. They should also have manuals if not I know they have part diagrams.
