Not sure where to put this as there is no training forum, but I bought this fun little laser for my 610 off Amazon. it was $25. It's called the Triton Aimsure and you can have the laser on full time to boresight, or in the dryfire mode, it goes off after you pull the trigger.
I just spend 30 mins in the basement shooting DA at various paper targets I have scattered around the basement. So far its pretty cool. Thought I would share.
