In general, yes! The 5900/5906 series served the Illinois State Police well for many years during it's issue with many Patrolmen opting to purchase their issued Pistol and Magazines when the agency transitioned to the Glock 22 and the, then trendy, .40 S&W Cartridge. Also note that during their service, these Pistols were fed a steady diet of +P+ 115 grain Ammunition from various makes and took it very well.
Parts that have occasionally required service have been Ejectors, Extractors and Extractor Springs, and regular replacement of Recoil Springs.
It should also be noted that the earlier S&W 469, 559, and 669 series Pistols were very good Pistols also. One of my relatives still carries an S&W 669 as his EDC and it continues to serve very well.
I had an early S&W M39 that proved to be a real lemon, barely feeding FMJ-RN, and it's ejector broke after about 300 rounds. Sent it back to S&W twice for repair, then after it's second trip back, traded it off for an S&W M19, which also proved to be a Lemon. This was back in the Bangkor Punta Days when S&W quality was quite problematic. I wound up arming myself with a used WWII Walther P-38, which I still have, along with two post war Walther P-38's.
Later on S&W stepped up their designs and quality and more local agencies adopted the second and third generation 9mm, .40, and .45 Caliber Pistols, and doing some gunsmithing for a local gunshop, I occasionally serviced them. Also later on, I acquired an S&W 4506 which proved to be a very good .45, but I preferred my EAA/Tanfoglio Witnesses to it, so it was sold off to an S&W Collector.
IMO, the third generation S&W 9mm handguns are very good, but you are better off with a Cz75 pattern handgun.
