Yes it can the 10 round mag is just a modified high cap mag for use in restricted states

Nathan, yes Sir it can. Most manufacturers including Springfield make firearm packages that have 10rd magazines so their pistols can also be sold in states that have magazine capacity restrictions. The pistols are exactly the same but just have 10rd mags included. The pistols will also accept any standard capacity magazines just fine.
