Gargoyle tech issue
I was able to secure a few 12ies from a friend today. I went out to shoot the garg after work, and ran into a bit of a problem. If I don't hold the pump handle forward, when I pull the trigger, the pump handle moves forward and backward a bit, but the market doesn't fire. Is there an adjustment that I need to make? Thanks for any help! Broch

You can try loosening the quick strip screws slightly. You may also try loosening the frame side screws, letting the bottom half drop as much as possible, then tighten them again.

Otherwise you can do what I did and sand down the sear slightly. Go slow, testing constantly, until it's exactly the way you like it. Then polish is with 1000 and 2000 grit sandpaper.

Just remember this gun has moded Lapco internals. Splattt would know best. I always keep my hand on the pump.

Worrptangl, that is kind of what I was thinking. My Grey Ghost doesn't do this, neither does my Bushmaster. I thought that it was kind of odd.

I would send splattt a PM.

I didn't have any issues with it other than it was 40-50 degrees outside so I had very bad efficiency, and subsequently didn't use it.

I sent Splattttt a PM, and his response may help several people here. It makes absolutely perfect sense. He mentioned that this is a common issue with cocker threaded nelson based pumps, and that it involves the o-ring on the bolt not being able to easily enter the bore at the back of the barrel. I'm going to try using a smaller o-ring on the bolt and will let everyone know the results tonight or tomorrow. Thanks to splatttt for this great tip!

I really don't see how that would cause this. I know it wasn't the case for mine.

Broch 03-15-2012 09:56 PM

I wasn't able to test the theory, as I have no o-rings
