You, sir, have a dilemma. You've chosen two great firearms! Can you afford both? I chose a Sig P220 Compact (it is a wee bit smaller than the P220) as my carry weapon. The grips feel great, so I haven't done anything to this firearm except to shove rounds down the pipe. And it shoots really, really nice. As for the H&K 45's. Excellent also, hence your dilemma. Certain H&K models have grips that are intended to be worn with gloves. (Well, that's the way they felt to me.) Without the gloves, those models can do some serious tuggin' at the range. H&K has other (newer?) models that have "friendlier" grips. The bottom line, no matter what firearm you choose: if it doesn't feel good in your hand, lay it down and walk away. Don't try to "sell" yourself on it. There are too many firearms out there. As for 45ACP, it's "the one" for me. I have never fired any other caliber that feels as good to shoot. I wish you only the best in your decision. As for me, I've narrowed my next purchase down to: another 45! I'm already savin' and plottin'. Good Luck.
