the early sigmas have a reputation for jamming,the newer ones are supposed to be "enhanced" how do you tell them apart?? are the newer ones reliable??are the mags the same or did S&W change them??do the 40 sigmas have a reliablility prob like the 40 glocks do??
Sigma's have gone throgh several configuartions Early models were "F" then "V" and now "VE, ie. SW40VE is the latest version of the 40 S&W. I have about 3,000 round through my 40 VE, and about 5,000 through my 9VE. I have not had a single hickup with either.
