Recently installed a JP enterprises fire control system with their low mass hammer. Took a little bit to get everything installed correctly but I finally believe I got this accomplished. Now that it is installed, I was trying to verify if the system would actually produce the 3-4 lb pull as advertised. As a comparison, my handguns have 1-2 lb triggers (setup for IPSC shooting) so when I tried to compare against this, it felt like I was pulling a ton. I don't own a trigger weight device to verify the pull, so what are my options? By the way, the trigger pull is relatively clean with a slight amount of take up at the beginning of the pull, but it lets off very nicely. |

You can build a "poor boys"trigger scale. Take a peice of steel rod or even a length of No. 9 wire about 30 inches long. Bend about 2 or 3 inches of it at a right angle at both ends. Next get a large tin can "about a gallon size" and with some more light wire or even duct tape fasten one end of the long wire to the can. Take this contaraption to the hardware store and weigh it on an accurate scale like they use for nails etc. Record this weight by writing it on the can with a magic marker. bend a 1/4 inch or so of the other end (not the can end) and put this end through your trigger guard and rest it on the trigger. With a little experimenting you can make the little bend hook onto your trigger and not slip off when you do the following... With the firearm pointing toward the ceiling, and the butt resting on the edge of a table, the can should swing freely being supported only by the trigger. Next add water to the can until the trigger breaks and drops the hammer. Do this several times until you are adding water a drop or two at a time to get the "precise" amount of weight to trip the trigger. Next poor the water into a common house hold measuring cup and that will tell you with in a quarter oz. or so of what the water weighs. Add that to the weight of the metal parts and now you have a very accurate measurement of what it takes to trip your trigger. It works. have fun... mark223 |
