A former employer issued Beretta 92s and Sigs of all models. I personally used three different 229s in 357Sig.
They bought the 229 because of its similarity to the 228, and chambered for the 357Sig cartridge for its flatter trajectory with greater energy downrange and, at the time, significant advantage over 9mm ammo. (Some European 9mm was hotter than our +P, so it was the exception.)
I found they felt like an extension of my arm and just seemed to know where I wanted the bullets to go. We dragged them all over the world, beating the &%$* out of them and they never faltered, even when inadequately cleaned and lubed.
I easily learned to deal with the DA/SA trigger and never saw anyone who could not.
I have purchased three of my own, all the older model without the rail. As someone else said in a post, I prefer those. One was given Novak's "Reliability Package." It already had SigLight sites or I'd have added Novaks. I have Novak sights on a 228 and prefer them.
I have not kept a round count on any of mine, but I know most of the ones my former employer had (all their Sigs, actually) had tens of thousands of rounds through them. I can tell you that for 10 years I put 120 rounds through mine each month, plus qualifying, and used it in IDPA competition. It will still hit a quarter at 12 meters, standing, hand-held.
"My" fourth 229 is being held in custody for one of our sons, who is professional military. He knows how much I appreciate Sigs and made the mistake of leaving it here when last he visited on leave. Somehow, it failed to go with him when he left . . ..
It is the Custom Shop Equinox pictured above, chambered in .40S&W. It is also the first Sig I have ever had trouble with. It just won't shoot straight. I had another .40S&W Sig 229 barrel lying around and installed it for a test. Same problem. Sooo, it's going back to Sig. Hmmm. I wonder if our son deliberately "forgot" it here so *I'd* be the one to do this.
I see by your subsequent post that you have made a purchase. I think a 229 in any caliber for $700 - $800 is a good buy.
