The Sig 229 has 13-round capacity in 9mm. The 226 has 15 rounds.Just to add to that, I carry a personally owned Sig P229R .357 SIG for work and I absolutely love it. It's an all around great handgun. I was going to get a USP Compact in .357 SIG, but in my opinion, the Sig balanced better than the HK. I've held and fired the P30 and it certainly lives up to the hype. Like the Sig, it's also a great handgun.
Are you looking for a 9mm or will any caliber do? The P30 is currently only available in 9mm. The Sig is available in 9mm, .40S&W, and .357 SIG. If I had to choose between the two, I'd still go with the Sig because my preference goes to the .357 SIG cartridge. In 9mm, the guns are both about the same in terms of what they have to offer. Both have 15 round magazine capacities, DA/SA triggers, decockers with no manual safety, and lifetime warranties. So I guess it would just depend on how you think the guns feel in your hands. Best thing you could do would be to handle both and if possible, shoot both.
I don't even own a 229 in 9mm so I am not qualified to opine. My suspicion is that you don't own one either, because if you did, I would have hoped to see a pros & cons post instead of the typical HKPRO blind devotion.Actually you got that right and the question is what fits your hands best! So you might like the P229 better. I daught it on the other side!
Well, to start with, I am a FFL and "see" therefore all kinds of guns, including the P30 and P229.... My suspicion is that you don't own one either, ...
