Colt SP1 6001 carbine

[Bill Hollinger]

I was looking over the 20 round magazines I have and comparing them to the magazine that came with the carbine and notices the pop rivet. Wondering what the heck I started putting rounds into it and sure enough, only five will fit. Is this how Colt did these? I know that all the books say they came with a five round magazine but I have never seen one. I have 15 Colt 20 rounders and none have the same round hole in the slit of the floor plate. I tried to remove the floor plate and it won't budge. I also noticed the five rounder that came with it has a small tab broken off Does the rivet need to be removed to remove the floor plate? I have no intention of messing with it at all, just curious.

Yep. I tried drilling mine out but haven't achieved it yet. It's pretty hard. I just set it aside. I have other 20 rounders.

That's a really nice carbine. Those stocks alone are worth a small fortune. Well, not that much, but they go for a good amount of money. Over 200.
