I saw a Sig P226 357 CPO in my local gun store for ever priced at $499. I kept thinking I'd buy it but would never shoot it due to the cost of the ammo. Went in there the other day and it was gone, regret....
You can buy 40 cal 226 and 229 for dirt cheap on gunbroker right now. PDs are switching back to 9mm so they are dumping their 40 cals. Get one of these and a barrel and you are good to go. 40 + 357 for <600.
