Byron, yes Sir. Most manufacturers including Glock make firearm packages that have 10rd magazines so their pistols can also be sold in state that have magazine capacity restrictions. The pistols are exactly the same but just have 10rd mags included. The pistols will accept either 10rd or higher capacity magazines just fine. Cheers and stay safe!

byron, Yes. Glock and other after market companies make 10 round magazines for every model and caliber of Glock pistols for the restricted states. There is not a model that the standard capacity is over 10 rounds that there are not 10 round magazines for.
