Flintlock LARP Pistol

I am working on repairing 3 of these items for an acquaintance. The sear cracked apart on all 3 of them. I am trying to drive out the spring dowel that holds the trigger/seer in place, so I can epoxy an aluminum C-channel to the broken portion for reinforcement.
I recommend increasing the width (not material thickness; that should be fine) of the seer so it is more resistant to breaking at the failure points, as well as adding a radius where it holds back the spring, to remove the stress concentrator that leads to snapping.
If the company is able to provide replacement parts and repair instruction, let me know (email recorded), and I will get you connected with the purchaser, fix this flaw, and adjust my review.
Thank you for your consideration.

...Ha, I see the owner posted his own review as well. Adding mine for awareness.

Bought 3 of these for larp and I got to use them for 3 events before all 3 broke as once the part the secures the firing mechanism is very weak for that it need to put up with. Were good but for the price vs durability I cannot recommend them.

Good for LARP, reenactment with youth, and/or certain SCA/HEMA specialist matches. Fairly durable, easy to use, and not too expensive. Wish it could fire darts better, but Nerf Elite balls are dandy. 8/10 would buy again if I had the money.
