I have three Sigs.....P226 made in Germany, P220R made in Exeter and P220Gen2 made in Germany. To me, there are no discernable differences between any of them from a quality/reliablity perspective. Personally, I wouldn't drop the grand until I had a chance to shoot both pistols you are considering. You might find the stock on the P226 too large for your hands, or you might find the positioning of the decocker lever on the back of the HK30 to be poorly placed. Or....you might find the double action trigger on the HK sucky. I learned long ago not to purchase a pistol until I've shot one first. Personally, I find the location of the decocking lever on the Sig to be better placed than on the HK....but that's just me. Good luck with your decision..... Wanna kill these ads? We can help!
