I have two T/C Hawken flintlocks, which are very similar to Investarms, they're serviceable, and usually reliable, the only issues have been the tiny fly tends to work itself loose during long shooting sessions, and fall out causing the hammer to fall to half-cock when the set trigger is used. This was a frustrating until I figured out what was happening, now I recognize what's happening and know what to do. Also, I think the spring is a bit stronger than it needs to be, which is hard on both flints and the Frizzen. Am sure a skilled and experienced gunsmith could probably tune the lock to correct these issues. I have debated whether to have it tuned, replace it with an L&R or other lock, or just enjoy it as is, until I can eventually get a Kibler kit or custom gun.
