Series 80 slide in a 80% 1911 build?


I've been slowly accumulating the parts and tooling for an eventual 1911 .45 acp build. When doing an inventory of the parts I have so far to determine what I need to order, I noticed that I had gotten a series 80 slide. Is it possible to use a series 80 slide in an 80% 1911 build, or should I get a series 70 slide? I have a Tactical Machining 80% government frame if that makes any difference.

If you leave out the vertical lock out for the firing pin it should work. How’s the slide fit the frame?

I want to do a build too I have a complete slide with parts and all the frame inners. I’m having a hard time finding a dealer to get me a new 1911/45acp frame. I purchased all the tooling from brownells for my norinco build already.
Ask yourself is what i'm about to do SAFE???? (From the national timber fellers association)

Gun Safety never sleeps or takes a day off, be safe do it right......

Yeah, just ignore that it's Series 80.
If you use a non-S80 extractor, the hole for the safety plunger is mostly filled.
If you're not shooting you should be moving. If you're not moving you should be reloading. If you're not shooting, moving, or reloading, you should be taping or picking brass. - Z.C.

Just ignore the hole. Tens of thousands of Colt M1911A1s with removed Swartz safety parts were issued during World War Two, yet we still managed to win the war anyway.
Avoid the temptation to replace everything on your brand-new 1911 just to make it "better". Know what you're changing out and why. You may spend a lot of money fixing things that weren't broken to begin with. Shoot at least 500 rounds through it first, then decide what you don't like and want to improve. Regarding vintage 1911s, pre-1970 pistols are highly collectible in original, unaltered condition and should NEVER be refinished or modified as it completely ruins their monetary value.
