re: Sig Legion

Having shot both 226 and 229 legions with DA/SA there's little difference. 226 grip is longer and narrower while the current 229 was built for a 40 caliber and is beefier all around. Depending on which grip you'd rather is a personal choice.

I like the 229 more due to it being what I consider a full size gun (fills the grip/all fingers with my glove size large hands) while maintaining shorter barrel/slide/grip. You can get 229 magazines with 15 or 17 (15s with a plus 2 basepad) - 10 rounders are for magazine restrictive states. 226 comes with 15s I believe but can easily get 18s with the same mag size. Good thing to note is the 226 mags fit (extend further out grip) in the 229s.
