In the rest position, the hammer on my 715 has a bit of play both side to side and fore/aft. Is this normal?
I'm thinking of cutting a ptfe shim to take up the side to side.

Mine has it too.
I did so something similar on an air arms trigger previously. Very thin PTFE sheet off eBay and just cut the washers to shape, I used scissors, I know one guy used a hammer and punch to make perfect circles depends on the clearance you need.

This is normal for the DW715 hammer, you can cut down on 'excessive' lateral play with some shims but you will need to leave a small amount of play to enable the hammer to move freely, otherwise it'll add weight to the trigger pull in double action, make it harder to cock in single action and even reduce the power of the hammer fall onto the valve. All three of my DW715s have a slight wiggle in hammer play but it is only slight, just be careful not to cause any binding and it might be worth thinking about using aluminium shims, which could be cut from cans of Coke etc.. The reason for the play is that the hammer spring is totally at rest (therefore no pressure is being applied to the hammer) when the hammer is down otherwise the hammer would rest pushed up against the (so called) rebound bar. I'd be very interested to know how you get on if you decide to go down this route and any information you can give to us about the thickness of the shims that you've used would be great too. I hope that helps Buddy  |

I was working on my DW715s today as I had to test fit a trigger rebound bar that I was making for one of our members ( pinguisgod ) and thought that it would be a good idea to check the hammer play on mine whilst I had the opportunity. The 2½" & the 4" were both 'spot on' with only a small amount of forward play (to be expected) and no lateral play at all but the 6" had the same amount of forward play and quite a noticeable amount of lateral play. So I decided to take it apart (which I had to do anyway) and investigate the reason.  The hammer had the exact same amount of 'wobble' once the side plate had been removed which was caused by either a worn hammer pin (which there was no sign of) or a misshapen hammer hole, which in all honesty I think it is due to the fact that the pin is made of hardened steel and the hammer is made of a much softer die-cast alloy and the action of the gun is just gradually 'rounding' out the hole. So in an attempt to remove this play, I tried to fit a small aluminium shim inside the hole to take up the slack but no matter how small I cut the shim it just wouldn't fit into the hole with the pin. Next, I tried a LDPE shim cut to fit the endplay where it meets the side plate, this turned out to work absolute perfectly. Before... After... It removed all the lateral play completely without causing any binding, I just lubed it up with a bit of silicon & PTFE grease and I'm very happy with the results. The LDPE came from an old 4pt milk container, once cut up you'll find that there are thick and thin areas to choose from for a suitably sized shim. I just punched it out with a hole punch and intentionally cut the inside hole too small so that it stays firmly in place once you take the side plate of, nothing worse than losing parts when you take the side plate off any gun. My thanks go to nikvanorton for noticing this minor fault and suggesting the possible solution, it's something that I hadn't previously noticed especially as it only seemed to effect the 6" version of the gorgeous Dan Wesson 715 revolver replicas. |

I can just picture the satisfaction on your face  What you do yourself you do better. |

Just done the same to mine - I had some ptfe shim material but it was too thick so I stole your milk bottle idea. No play whatsoever now, feels SO much better. It may be binding a fraction (and I mean a fraction) so I'm going to bed it in for a while and see. It's absolutely spot on now, can't believe the improvement.  |

I think that your shim might be too wide as the side plate has a recess for 'hump' in the hammer centre around the pin.  The red arrows match the far edge of the recess in the side plate for the 'hump' to fit into and the green arrows represent the maximum size of the shim, otherwise it will be distorted out of shape as the side plate presses onto it which will definitely cause binding buddy. You might just have to trim the size of your shim down to stop it binding against the recess in the side plate. It was something I noticed when I did mine. |

WTF:) I tried to do this right down to the smallest shim i could find. I tried a piece from a pop can, I can't remember off hand what was the smallest material I tried. It would not let me cock the hammer no matter what  I actually was talking about it in the 715 post in here a while ago, need to take some notes  This is the only problem I found really with this 715, |

If you still cannot get a shim in there, of any size, then the gun doesn't need a shim it that position and the fault lies elsewhere. If that's the case then I'd check the hammer pin to hammer fit, as that maybe be overly worn (rounded out by the action of the gun), if that's the case try putting a 'pop can' shim between the two to take up the slack. |

If you had calipers how thin are the shims you's are using?

I might have tried to shim in the wrong place.
