I got a deal on a HK P30 a few weeks ago and it's the DA/SA version with the decoder and without the safety.
I was at a store today and fondled P30L with an LEM trigger and it was much better than the version I have.
I vaguely remember hearing that it was possible to swap triggers but googling it is turning up a lot of mixed info so I thought I'd make a post. Sorry if this is has been covered before.
