I have always wanted to bob the hammer on my SA MilSpec since I got it. Is this going to have a negative effect on ignition?

I cut mine down with a dremel tool to avoid hammer bite and it had zero effect on ignition.

This^^

Mine was done by a smith, but the end result is the same. No more hammer bite, but enough of a spur to allow thumb cocking and no problems with ignition.

Bobbing hammers is also done to decrease lock time (the amount of time between hammer release and impact), which can improve your accuracy (not the gun's inherent accuracy).  I've only heard of ignition problems when done to revolvers in conjunction with lightening the hammer spring. Bobbing the hammer probably had nothing to do with the ignition problems, which were eliminated by tuning the hammer spring. .

Nope,.......many will shorten the spur by two or three serrations

A bobbed hammer is functionally no different than various light weight hammers in terms of ignition.  Assuming the hammer spring is adequate, the lighter hammer will have more than enough momentum to activate the primer.

Seriously, you could have the hammer cut flush to the slide and still have reliable ignition.

Hey thanks guys I will probably go ahead and have my smith do it unless I can find a dremel to borrow

True.  I did a lot of work for a fellow who used to like to do this to his hammers.  Never a problem with ignition.   Plenty of OTHER problems but nothing hammer related.
