I have two single stack detachable mags one that will hold 5 rounds and one that will hold 10 rounds that I don't need any more if you are interested. will sell at a good price (1/2 of what i paid for them) they are new and come with the floor metal.
I will have to measure the inside length to see what COAL it will handle.
PM me if you need them and I will text you pictures and specs.
