Nice choice, you improved it nicely. And I agree with the above sentiments, Sigs are the Cadillac of pistols, especially the Classic P Series. I have a 1989 W. German I bought new, only malfunctions were 2 decades ago trying to get through a box of surplus Egyptian army ammo (stuff was turning green!), otherwise it's been 100%.
I have several, including a P226 DA/SA .357 Sig ex-Texas DPS Highway Patrol I bought when we transitioned to the DAK system, a DAK P226 .357 Sig ex-THP, 9mm M-11A1 in FDE, 1994 DA/SA P229 .357 Sig, P239 DAK .357 Sig, a P229R like yours in .357 Sig (my Dept. still issues that round, so as long as I can get it easily I fortunately don't have to struggle with its price) and a blue P230 in .380.
Next up, whenever I can, will be a P225 9mm (the old one, not the new one), a P227 in .45 ACP and lastly, when I sell the kidney I don't use, a P220-10 in 10mm.
Great, great guns! Enjoy it, it'll last forever!
