I think the answer is still gen3 Glocks everywhere... I have enough G17's to do that, but for some reason I have different models everywhere... two are G17RTF and one is a G22C though. I like a 30S in the kitchen. If you love those PSA's you could just buy a $120 slide and build it up or whatever they cost... and slap it on your gen3.
What are the hot new roster guns now? P320's, XDM's and VP9's? I guess we don't have it that bad right now.
