Lam,
Have had and have several Charter 44 Bulldogs, 2.5", 3", 4". They all shoot and carry great. However, one caution! Their "unbreakable" copper / berylium firing pin, is very "breakable"!!! I have about six extras. Nonetheless, if you "dry fire" with snap caps, you will be OK. Great guns, I've had 'em for over 25 years and can't wear them out.
