My dad has an older .38 spl s&w, it's a six shot snubby so I'm guessing its a pre-K frame (no letters , just a serial #)
Once in a while it wont fire a round on the first strike and I'm thinking it may need a new main spring. The same ammo shoots fine in all our other .38s and .357s
How hard is it too replace it, and will a newer K frame spring fit or are they different ?
