Look in the used section, likely your best bet. We have to keep in mind, typically, a new aftermarket slide costs roughly between $120 to $200 (and up) in Canada: A&A has an entire G23 for $220, so about 260 after taxes and shipping. Best case scenario, cost is about half a whole new Glock: Worst case, you're less then sixty dollars away.

Best idea: look for a "possessed" G23 for sale for the parts. I've seen a few at less then half the retail price, which will get you a metal slide, occasionally some spare mags, and a bunch of parts for future replacement if need be.
