A few years ago, I purchased SW 642 with the factory lock. It has been flawless, and has a butter soft trigger action and I have had no problems with the lock. As I have seen some very negative reactions to buying a SW with a locking mec. I was wondering what the experience of everyone was with them. Evan Marshall on his web site said an average owner should expect zero problems, but I see there's even a YouTube video on removing said lock due to possible malfunction. If you own or have owned a locking SW revolver, what has been your experience pertaining to reliability? Again, I have never tampered with the lock other to check its working. I have kept it unlocked since purchasing it. Zero problems with several boxes of ammo including +P. Thanks in advance for the replies. Gray_Rider Wanna kill these ads? We can help!
