To the OP congrats on the sig I have several great guns.
And as for the posters that have had trouble with the trigger springs breaking were they installed wrong or something?
I had a friend with the problem and it was caused by after market grips being installed incorrectly.
I have four sigs all p220's and have thousands of rds thru them all and and have never had a problem. Two of them I have changed the trigger springs simply because of rd count suggested it was time.
BTW to the OP sigs are great dependable guns things can break on any gun but learn to take care of it and a sig will take care of you!
