Well I went and paid it off a little earlier than I should have because I'm impatient. Disassembled it to find there is a recoil buffer installed so at least I know whoever had it before me actually cared.
I don't know a whole lot about the 1991's, or Colts in general for that matter, and what they come standard with. I do know (thanks to you guys) that the sights, the extended safety lever, the magazine well funnel, and the grips are all add-ons to this pistol. Not sure about the beaver tail grip safety though. I'll take a better picture soon so that can be seen.
I've read that the triggers the 1991's came with were plastic but this one has a metal adjustable trigger so I'm assuming that was added after the fact as well. The trigger feels good to me but I don't have much experience with anything to compare it to.
Someone mentioned that the roll marks look faint but it was just the crappy picture I took. I inspected it and had some others look at it too. The consensus is that it hasn't been refinished or shined up. Just a stainless Colt someone put some bells and whistles on.
The tritium on the sights seems to be spent so looks like I'm going to be in the market for something to replace those. Anybody have recommendations for some good sights?
Someone asked about the wear on the inside. The feed ramp looks good and it doesn't look like its had too many rounds through it but I'm no expert to judge on that. Standby for some better photos.
