you can convert from da/sa to LEM I don't remember the exact cost but it is cheaper than going from da/sa to DAK in the sig. I have both and while i like the DAK trigger a better than the LEM. And i like the DA/SA in Sig better than HK. But that said i would go with the p2000 sk ether in LEM or DA/SA. I do want to say that while every one is bashing the 224 for being to heavy i really like the size and weight for a 40 cal. The grip length allows me to conceal it very well and the weight allows me to shoot it very well. It is a god compromise for me. But overall i would suggest the P2000 Sk over the 224. I just got a very good deal on the 224.
