New series 70 Colt
So I picked up this very nice Colt Series 70 the other day at my local shop for $600 and I'm very excited to own this gun.

I didn't know much about this gun when I bought it but it seemed like a good deal and I couldn't pass it up.

To be honest I don't know much about this gun but I've been doing some research online and I'm pretty sure this gun was designed to fire wadcutter/semi-wadcutter ammo and that shooting ball ammo can cause damage, is there truth to this? I can't find an markings on it to determine who did the custom work on it either.

The person who owned this gun before me is an employee of the gun shop where I bought. He put this gun on consignment with the shop and he doesn't know that I bought it yet. He's been on vacation for a week and will back at the gun shop tomorrow so I plan to go in and see what he can tell me about this gun, in particular what has been done to it and who did the work.

Here's a few pics....

not true they were designed to fire 230grn FMJ.

i see you have a buffer recoil pad on your guide rod. those things can cause feed issues by not allowing the full operation of the slide.

The BoMar rib is an add on. As stated, you have a standard Gov't model modified for the rib addition. From a value standpoint, the slide modification takes away the "original Colt" price point and diminishes the value. This means that it's worth what someone will pay for it. To a Colt collector, this gun is of little interest, unless a S70 original slide is fitted.

The pistol may have been intended to shoot wadcutter low velocity target style matches.The target rib was pioneered by Jim Clark over 40 years ago. It is a quick and dirty way to get a flat top slide, with the rear sight overhang to extend the sight radius
for target work.

Make sure you check what recoil spring is in the gun before cutting loose with major power loads.

Like the previous poster states, I would loose the shok-buff as well. When they fail, your pistol will lock up, you can't tell when it's coming.

I'm sure you are happy with your purchase, not trying to flame here. Looking at your pics, this pistol has been used pretty hard, especially with what I can see on the internals. Not to say that is a bad thing.

I personally would have put that $600 towards an unmodified S70, which, depending on condition, can be found readily on Gunbroker for just a few more bucks. But, I'm not you, so if you're happy good luck and happy shooting.

I thought there was some new type of Colt rifle.:eek:

That looks like a Clark Custom setup for wad cutter in old Bulls-eye matches.

I'm not so sure, Dan. My 70 Series Clark Longslide had a full BoMar rib and there were no screw holes through to the inside. Clark also marked the guns they turned out with their name. I'm thinking this one was done by someone else.

This gun has seen a bunch of use and looks great. That rib adds weight and will slow down slide velocity. Who's barrel is in it? I can't make it out. Nice Kart NM bushing, if it was installed right. Does it need a bushing wrench to remove?

From what I can see, I'd pay $600 for that gun all day long (but I'm a sucker for old Colts). Can I have it?

Great pictures. I would love to have a pice like that.

M14, that is why I added the word "like". I think that the AMU also did some of those, also.

Still, it is a good looking handgun.

My Clark longslide was one of the 100 made for the AMU with the 6" S&W barrels. Did AMU make some as well?

I built quite a few similar to yours back in the 70s for bullseye competition. I used the same rib, but all of mine had a lowered and flaired ejection port, skeletonized trigger, extended slide release and safety. If you decide to use 230gr ball, be sure to install the appropriate recoil spring.
