I like my Sigs. I carry a P226 in .40 on duty, a P239 9mm off-duty, and keep a P220 with a weaponlight attached in my nightstand for HD.
Congrats on the P229, its a great gun. Remember to lube those slide rails. I prefer a light coat of grease on the rails to oil. Stays in place, doesn't cook off, and seems to last longer during extended shooting sessions. I use white lithium of Hoppes grease, both are very affordable.
Owning and shooting alot of Sigs I can always spot the guns that were properly lubricated and the ones that weren't by having a glance at the slide rails. I recommend carrying the gun with a light coat of grease to ensure function. Dont be afraid to slather it on before you hit the range.
