Glock 23 still available...
Fresh list of full and partial trades I would consider:
1911s of all shapes and sizes
Glock 17 or 34
Ruger .22 semi auto (prefer stainless)
Ruger Single Six
S&W J-frame (prefer alloy frame, prefer pre or no lock)
A good 12 gauge shotgun (870 polices especially, but will consider all)
Seriously, make me a trade offer! I will kick in cash and/or high end accessories for the G23 for the right deal.
