Slide not locking on empty mag is a frequent problem with the 226. Either from riding the lever from a high grip or weak ammo not giving enough time for magazine follower to spring up. I see it every time I see someone shoot a 226. "Just change where you put your thumb" is usually the 75% solution. You can try replacing the lever with a 224 or legion one where it sweeps forward more. Also the wraparound e2 grip makes it easier to ride the lever. The other 25% is shooting a slightly hotter load then regular 115s, or go 124gr. My personal opinion is da/sa is obsolecent for the reason that having 2 different trigger weights is questionable. 226s do come in SA only version with no decock and manual safe. Beyond that, the 226 is very serviceable.
