I sent both my Sigs (220--.45 ACP & 226--9mm) back to Sig after shooting them about 2 months...they had some creep and I had been advised that at the Sig factory shop they will take a look and if possible improve the trigger.
Well, I didthis... I got back two "factory" guns tweaked by "factory guys/gals" which are so fine, I would refuse a free "trigger job" from anyone on these two guns.
Sig gave me such impressive customer service! I really enjoy spending my money on Sig products!
Let's see, my Sig "want-to-buy" list...220 Stainless, 6" Trailside, 210 (I know, I gotta keep buying lottery tickets for this one)...on and on!
