i second buds. they almost always have the best prices bar none. esp if you dont live in kentucky. you take their price, add 3% if you are paying by CC which i always do, and add $25 for my FFL transfer. even after all that they are still way cheaper than local which is the price you see + sales tax, and any other online store. plus they are fast. you can get a gun in a week of ordering it. ordered on monday, got it monday of next week.
honestly I think the other stores just resell buds guns at a markup, cause they never have anything buds doesnt have for lower.
impact guns sucks, they take forever to do anything, and they are expensive.
I live in texas so i dont shop with them, but you can also try out able ammo
they seem to have good stock, and fair prices
