The DS-10-SPEED is a custom made speed loader for the 10 shot S&W 617 revolver. --- I use these for my pin shooting competition to reduce the time required to load. --- I searched for years for a speed loader for this model but no one made them, so I decided to make my own. --- These were designed for 617 revolvers with the stock rubber grips and other grips that accept speed loaders. --- No color choice for loading blocks.----- (Don't click on "Join Now") --- Please send email to: ds-10-speed@hotmail.com -----(Click on PICTURES for more info) ---- ( for .22 rimfire only ) ---Dave Skrzela (New redesign on 10 shot speed loaders reduces the force required to load the revolver, June 22,2008)
