A 5906 slide on a 3906? I'd rather have fixed sights than the adjustable ones.... 

Like it was made for it.
P.S. It was.

Please post photos when you're done doctor!![]()
cpeblue,
Does that say SLPD on the frame? Could that mean St. Louis PD?
I don't recall seeing St. Louis Police Officers carrying the 639.
BTW I also prefer adjustable sights on 4" and longer barreled pistols.

Could also be Salt Lake PD or San Leandro PD or . . . .I never found out what organization SLPD stood for but you are correct in assuming it's not St Louis, they were never issued 639s.
A 915 slide should work - there are differences in the 910 slide that would prevent it from working.
Why change slides when you can install aftermarket adjustable sights?
