Problem removing sausage Rated 4 by Anonymous
I install auto glass and have used the 14.4 version for several years and is why I stayed with Milwaukee. This gun has great power, battery, and accuracy. The only problem I can find is that the sausage consistently wraps around the end of the plunger and is very difficult to remove. I would give 5 stars if this wasn't the case!

full time caulker Rated 4 by Anonymous
im a construction caulker. I have this gun in my hand 6 days a week. all in all great gun. the problems I have with every day use is: 1. not an optional ladder hook to go on end of the drive shaft. the 2 hooks are to small for most areas to hang your gun especially when on a 20-32 ft ladder. 2. plunger after time starts to lose its seal and allows sausage to get by the side of the plunger making it a pain to get out. people using make sure to push the shaft all the way forward before unscrewing the cone, thatll make the empty sausage come out easier. 3. if the motor gets the slightest bit wet the release action seems to freeze up. ur pretty much screwed after that till it dries out. 4. speed goes to 6 with a full control trigger which I love. I just turn mine to 6 then adjust speed with the pressure of my finger. a subcontractor we work for has the mikita model. in Milwaukee numbers the mikita turns up to about 9 but is more all over the place. a 7 or 8 speed on the Milwaukee would be awesome for big windows or tilt panel buildings. my forearms have never been so happy tho, no more pumping a gun. the electric is quite a bit heavier but not having to squeeze makes 1 handed shooting possible. if your getting this gun and usind it a lot it may be worth ordering a couple extra plastic plunger pieces with it. the metal washer behind it should not need to be replaced sawtooth caulking
