Please note: the frame of the "Standard" 6904 is a Compact frame. Confusing.
My previous 3rd. Gen. (5906: solid Steel frame and slide) was bought just for variety at the club.
But being curious about the lighter weight 3rd. Gen. options, bought both a 908 and 6904 last December on GB (prices weren't bad, considering...). * Despite the 908 having only Three numbers, it's also a 3rd. Gen.
Sometimes the 6904 is carried, and prefer the even better ergos of the 908. Mostly carry the Walther P99 AS in the summer, Only due to the > plastic frame against sweaty inner t-shirts< .
If you are Really Into these guns ("obessesed" ,
my wife's words - never mind her dozens of hand-made 19th Century German Meissen figurines) , there is a > list with tiny print < on Google images ( ** won't let me paste
), which lists many more variations. That long, Non-graphic list "blew me out of the water".

S&W 3RD GENERATION DISASSEMBLY/TEARDOWN (FRAME) VIDEO #1 OF 4 - YouTube His videos are excellent, close-up, well-illum. and his techniques are clearly explained.
My only previous dis- and reassembly of Any handgun frame (never did any slide) was the Sig P6. You can easily 'do' both guns' frames with the right videos.
