magazines. I have a number of 17 round and 30 round Glock mags for the Ruger PC 9 and have seriously thought of buying Glock 17 gen 5 mod. But am conflicted because I have a number of SW, CZ and Springfield 9s as well. But the compatible Glock mags make it very attractive to buy the Glock 17. In the face of the civil disturbance I'd think that if all hell breaks loose, having the same compatible switch off mags for one or the other would be be great. But I have several 9's now. What should I do?
