HK45 D/A only?

[Sun_Tzu]

Is it possible to get an HK45 LE trigger, and have it tweaked to a 3.5 pounds reset like my G34? I know they are entirely different pistols, but I love the trigger of the G34, especially in a D/A style combat pistol. Has anyone ever done this? Feed back is always appreciated. I'm wanting a nice .45 pistol. I don't want a 1911 (too finicky), and my only other options are HK45, M&P .45, and SPA XD .45 (hopefully they come out with an "M" version). The reason for my choices are simple, grip size! USP's, and G21 (SF as well) are too big for my hands. I would like to think the HK45 is the best, and most likely is probably the best one by a long shot on many levels, but I know the new M&P .45's are quickly becoming a favorite amongst many shooters, not to mention that it's much less expensive, and you can have that trigger work done that I mentioned. All I need to know is if it's possible, and how much am I looking to spend? If it can be done, then I'll be getting one before the year ends.

Thanks in advance.
