I’m going to list a few facts about me so that you will know that my choice is not brand biased, but from experience.
I’ve been shooting 10 mm since the introduction in the 80’s and have accumulated quite a few tens.
I am a 1911 guy at the roots.
By looking at my Sig collection you would think that I’m a fanboy, but most Sigs leave me disappointed. I think most are overrated.
While I have a handful of Glocks, I don’t shoot them, even my semi custom G20 10mm. I find them mediocre, not enjoyable/fun.
As of now, I find the Sig 220 10mm to be a beast! I have the Legion, not that it matters. It does a great job at taming the 10. I’m not a fan of the 45 220, I never shoot the 2 that I have. But I was pleasantly surprised by this 10 mm 220. It’s a winner for me.
If the Sig is not in your budget, my second choice is the XD. I was surprised how much I enjoyed that 10 mm as well. Mine is the 4.5 model.
I am very curious about the SW MP 10 and XD 3.8.
