I e-mailed him about the Welsh Willy triggers maybe a week or so ago and there's some turn around time (14 days?) but as of my e-mail, they were available, I think it's about $38.60 US, but you might want to try e-mailing him to see how much shipping to the States is.Sent him the e-mail because I've been looking for a fix for the trigger on my Hatsan Edge .25 which from the little I can find, is a less expensive version of the Striker and has the same trigger set up. I posted with pics of the trigger in the Welcome section if you want to take a look and compare yours to mine.
I went looking for the original reply he sent me and can't find which folder I buried it in, but I do remember him saying it should work on my Edge which led me to figure they were available. The only reason I didn't order and kept looking for more info was because I figured if the shipping prices to Canada and the US were roughly the same, it works out to almost $39 for the trigger and close to $45 for the shipping and I only paid $89 for the rifle. Love the rifle and definitely want a better trigger, but the cost for now is something I'm still in serious debate about, which is why I suggested e-mailing him to ask about US shipping fees and something I had a brain fart on and didn't do and should have.Here's the pics of my trigger and thanks for the welcome to the group!
Found the link to the other post I saw, pretty in-depth, but worth reading maybe? http://www.gatewaytoairguns.org/GTA/index.php?topic=84653.0The screw on mine took a flashlight to find, it's seriously small and tucked in at the very base of the trigger on the backside...never did try getting a screwdriver on it.
