For those of you in need of a bluegun, but dissuaded to make the purchase because the Bluegun thumb safety is in the “safe” (a.k.a. not cocked & locked) position, here is a couple photos of my recent attempt to modify my Sig P938 dummy to put the thumb safety in the locked position. Unfortunately, I didn’t think to snap a pic before I made the mod, nor did I snap any pics during the process.
If you’d like to attempt this on your own bluegun thumb safety, you’ll need a couple tools:
- Heavy duty razor blade – I used a box cutter style folding pocket knife with replaceable razor blades
- Super Glue
Begin by slicing along the frame as best as you can, making incrementally deeper cuts. In other words, start slicing close to the beaver tail (in this particular instance), then slowly cut deeper, moving towards the grip area. You’ll eventually get to a point where the material is too difficult to cut, or you can’t get your blade any deeper because it’s hitting the slide or grip area.
At this point, switch to the chisel. You’ll need to make “stop cuts” around the grip area to help free the safety from the surrounding area. Place your chisel vertically (perpendicular to the dummy) and gently hammer the chisel till it touches the “frame”. If you forget to make these stop cuts, you greatly increase the chance of your safety breaking if you proceed with the next step.
If you place the muzzle against your table, you should be able to gently hammer the chisel to cut the safety away from the rest of the dummy. I can’t guarantee your safety won’t break when you try to remove it, but the material these dummies are made of is relatively flexible. My safeties flexed a bit as I carved them away, but they did not break.
Do a little clean up around the top edge of the safety if it’s supposed to rest flush against the slide. You may also need to shave away small bits of the slide and back of the safety to make them flat for a better mating surface.
Using regular super glue, you should now be able to position the bluegun thumb safety in the correct “locked” position and glue it in place.
