COLT 9mm OWNERS – PLEASE HELP!

I’m thinking of purchasing a Pre-Ban Colt 9mm and have some concerns.
When I was looking at the gun I had notice where the 9mm block pins go through the mag well, it looks like round circles around the holding pins from some tool Colt had used. Is this typical or do you think somebody had been screwing around with the gun?
Any pictures of Colt lowers showing the holding pins would be appreciated.

Thanks Colt 9mm fans.

I think you are talking about the old 9mm block system that Colt used to install the lower. In order to hold the adaptor block in place, Colt had to drill and insert pins to hold it place. The newer block uses set screws to hold it in place.
Go to these places to order the newer block design.

All factory Colt 9mm guns did have the pinned in mag blocks.  More importantly than just being pinned in, they also had springs tensioning the blocks into place.  Colt never used the one peice blocks in a production gun, but they are nice for conversions.
As to the marks on your lower, I've seen them on every 9mm guns I've seen.  It looks like the tool that they used to hold the pin was not dressed nicely, and was definately harder than the finish on the receiver.  This left a small ring or blemish on the reciever just off the pin.  Don't worry about it, as it really doesn't hurt anything, and they all have it.

I have the 9mm car, nomarks on mine!
and as far as the pins go, its the best set up for 9mm.
