Re: Worth the risk?
The newer models will probably function just fine, but the fit and "feel" of the weapon just isn't quite the same. Statistical differences in reliability would be almost impossible to come by, but it should be noted that there's a certain anecdotal trend in LE circles within the last year or two away from Sig products due to QC and CS issues. One of the largest agencies in the state just de-listed Sigs as an approved carry option, leaving Glock as their de facto standard. Publicity issues over certain large federal agency contracts are widely visible online, including Sig's response to criticism.
Put bluntly, Sig management needs a shakeup, and the people in charge need to return back to their focus on making a superior product their highest priority...not just boosting their quarterly profitability.
