need to buy a hammer extention for my T/C ENCORE scope is mounted low [the way i want it to be ] and now it is not very easy to release the trigger ,in a no fire situation ..i saw an aluminum hammer extention which looks good ..also red on the forum that i could run into some problems with the hammer extention because the spring is not strong enough ...

Have a bunch of hammer extensions. The best one for the Encore is the one inyour photo.

Never had a misfire using the original hammer spring with the hammer extension and the muzzleloader barrel.With centerfire barrels it is another situation.Installed my .30-06barrel at the range. Another shooter told me: "You will have a misfire with that hammer extension." He was right. Get the stronger hammer spring from bellm:
