I’m curious how you can have 15 round Glock mags if you can’t have 15 round Ruger mags.

“I’m curious how you can have 15 round Glock mags if you can’t have 15 round Ruger mags.”

When I bought my Ruger P89 the only ones that store had were 10 rounders. The model I have is a single stack, not a double stack.

I said “single stack” mag because the cartridges load atop one another, rather than a distinct offset as one would find with a double stack mag. However, it appears the main reason the mags are 10 rounders is that there is a “pin” near the bottom of the mag that keeps a bottom plate in place, and that limits the number of cartridges. There are P89 mags that do not have that pin, and that particular bottom plate, and those mags will handle 15. I know there are after-market P89 mags that are like that. But, for whatever reason, the store from which I purchased this model only carried the 10-round mags.

Also, I changed out the grips a few years ago and that made a difference in ergonomics, for the better.

I consider my P89 as more of a back-up gun to my Glock 19.
