Sorry...I have found .45 and .40 are the same price on ammo, maybe a little higher on .45.
I believe the 38 would be close to the 9mm. Don’t quote me on that though.
Walmart doesn’t sell ammo in California.
Aim has .38 for $11.95 and .45 for $15.95
With our sales tax at 7.75%, it should come close to covering shipping.
