The Battle of the American .45 ACP Pistols, late 80s to early 90s edition.

The late 1980s and early 1990s was an era of rapid transformation and transition. The last final gasps of the Revolver as the Primary Duty Sidearm of American Law Enforcement was being heard. Criminals, Cops, and Citizens alike were rearming themselves with the latest and greatest of the Wonder-Nines. This article is in no way about those guns. Instead, this article is going in a different direction. The same direction that some Police, Citizens, and Ne'er-do-wells went. Today, we're talking about the .45 ACP, or more importantly. Two pistols of the era that were chambered in them.

Yes, you read that right. We're goig to discuss the two guns chambered in the cartridge that Americans romanticize about but has always been treated as the stepchild in the Law Enforcement world. The biggest hurdle that the .45 ACP has always faced has been its size. Many love the 230gr behemoth because it harkens back to the days of cavalry charges with sabers and shooting a horse out from under its rider. But that also was its detriment. The size of the .45 ACP meant it was and is a big mamajama of a cartridge and to fit it in guns, you need a big old honking chunk of steel. And today we're looking at two massive chunks of American made steel.

Colt's Patent Firearms Manufacturing Company of Hartford, Connecticut has been making guns in .45 ACP since 1905. They invented the bloody thing. So it makes since that one of the guns we'd be looking at is a Colt. I know, some here are gonna ask, "is it the Colt Series 90 Double Eagle?" Alas dear reader, no it is not. For you see, I am poor and have not found one yet at poor people prices. No, the gun we're discussing today is a gun made for poor people like me; the Colt 1991A1 Government Model.

Image

Colt took the basic MK IV Series 80 Government Model 1911 and looked at what could be changed to lower manufacturing and production costs. One of the things Colt learned from their competitors was that at the time, the no-nonsense military look was actually selling well. Both the Norinco and Springfield Armory made guns looked like WWII era USGI contract guns. Luckily for Colt, that meant less time finishing the guns. Instead of the polishing and blueing; a "no frills tough guy attitude" set of features was included. A matte parkerized finish was applied, black plastic grip instead of woods, a nylon mainspring housing and trigger pad instead of alloy, a set of plain black sights, and they shipped from the factory with two seven round magazines.

Image

Also, with a bit of clever marketing, a simple "COLT M1991A1" slide rollmark and the serial number range picked up where the original USGI contract pistols left off in 1945. Colt even cashed in on the general gnashing of teeth that former service members and gun aficionados had towatds towards the adoption of the 9mm and the Beretta as the new military service pistol and had it all ready for release by it's name sake, in 1991.

Image

The other gun we're looking at is a gun of 80s Reaganesque Awesomeness that comes to us by the Smith & Wesson Company of Springfield, Massachusetts. S&W had some history with the .45 ACP, but prior to 1985, all of the company's endeavors with the cartridge was with N-Frame Revolvers like the M1917, Model of 1955, and the Model 25 & 625. S&W was doing fairly well with their 1st and 2nd generations of their DA/SA 9mm guns. But the market was demanding something in .45 ACP. So after some fiddling around with math, science, along with some Dungeons & Dragons Satanic gun alchemy. The Mod 645 was born in 1985 and replaced in 1988 by the 3rd generation Model 4506.

Image

Taking everything S&W learned from their 9mm guns, they produced a hell of a gun in stainless steel. Everything on it is stainless steel except the plastic orange insert in the front sight and the carbon steel rear sight. Shipping from the factory with two eight round magazines and wearing a set of plastic checkered grips. You got a hell of a gun.

Image

But this gun was not cheap new, even in 1980s Cocaine Fueled Economic Stimulus Money. S&W pushed this gun heavily and it even became the "star" of Miami Vice in season 3 & 4. This gun was marketed as being so cool, it required a windbreaker.

Image

Yup, that's what is being compared to today. A 1980s Movie Star and a 1990s Grizzled Old War Vet. But both have their share of charms in their own way. The Colt weighs in at 2.3lbs and the S&W just tops it at 2.4lbs. Both sport a five inch barrel and have been slightly changed by me.

Image

My Colt is wearing a pair of period Hogue wrap around grips the the S&W is wearing a pair of Pachmayr Signature grips. I also swapped out the main spring housing on the Colt for an arched one. You can clearly see the 1911 inspiration in the 645. The slide profile and general layout shows it, but with the modern touches like a ambidextrous slide mounted safety/decocker and squared off combat trigger guard that was all the rage then. The sights are similar too, but the S&W just has a little bit more flair in theirs.

Image

Neither are bad and my blind self is able to see the sights clearly and feel confident and comfortable in using both.

Image

Another difference between the guns is the extractors. The Colt has the ever classic internal extractor while the S&W has an external one. Both guns are reliable enough that they feed and extract empty shell casings.

Image

Capacity is what you'd expect. The factory shipped the Colt with seven round mags, but I have a pile of Colt eight rounders. So both guns are equal with an 8+1 capacity. Also, both mags are all metal with metal floor plates.

Both guns take down in a similar fashion too. Unload, remove the magazine, pull the slide back about half way, and drift out the takedown/slide stop pin.

Image

The Colt breaks down into nine parts. The Colt likes to eject the recoil spring plug half way to the Moon.

Image

The S&W breaks down into seven parts. It has no recoil spring plug and no removable barrel bushing. But it sure does love to launch the guide ride to Pluto.

Okay, now that we got the nitty gritty techno junk out of the way. Let's look at what's really important. Worthless personal opinions from a cop who's professionally carried nothing but GLOCKS in 9mm, .40 S&W, and .45 GAP in his entire decade and a half career!

So, the Colt of course being a Series 80 1911, it has the firing in block safety installed and that is something true dyed in the wool 1911 aficionados hate. Why? Because they claim it ruins the sweet succulent pull of a 1911's trigger. Me personally, I don't care much and can't really tell the difference. Having cut my teeth as a wee pup on guns like a Beretta 92FS and a S&W Mod 64. I pretty much don't begrudge what some consider a bad SA trigger pull.

Honest, I don't mind the factory trigger on a Series 80 1911. The gun shoots fine to me for its intended task. Being able to sling 230rd chunks of copper jacketed lead at paper and bad guys. Being a SAO gun, I'm fine with that too. But I can tell you this, Agency Administration would have a heart attack for the most part in seeing a cocked and locked 1911 in a Patrolman's holster. Yes, I know some agencies allow 1911s to be carried for work. But some agencies also allow Firemen into the squad room for some reason and it isn't fornhazing or ridicule either. So for the most part, a 1911 is verboten for police work. But I wouldn't feel under-gunned with one if allowed.

Now, the S&W was made specifically for Law Enforcement and the Agencies that have mental conniptions towards 1911s that rival those of a college student when you tell him he actually has to get a job and pay for his own things.

The S&W being a 2nd generation DA/SA from Big Blue means that there was still a lot of refinements needed to be made. Those were fixed with the 3rd generation. But I feel there were more issues with the 9mm guns than the .45 ACP guns. Comparing my 645 to my 4506-1.

Image

The changes were not as dramatic with the .45 ACP guns as they were for the 9mm guns. The 645 and 4506-1 are pretty much the same except the 3rd gen gun was a post 1998 model so the trigger guard was rounded instead of squared off and the sights are Novak pattern. The original 4506 had a very similar appearance to the 645, except it had the one piece wrap around grips that also worked as the mainspring housing instead of the two piece panel grips and a separate mainspring housing. I actually find the grip profile of the 645 to be better than the 4506-1.

Another good thing about the 645 was that since it was replaced by the 4506, that means in the early 1990s. You can get a new 645 for a good price since dealers were trying to clear out their inventory to sell the new hotness that was the 4506.

The trigger pull on the S&W is very good for a DA/SA. Smooth in DA and a very short reset and pull in SA. And that means the gun can be carriered with one in the pipe, hammer down, and safety off. And for police work, that's damn good because there is no safety to fumble with. Sure, I personally feel confident with a 1911 and having to disengage the safety. But we all know that not every cop is a gun guy just like not every soldier is a Green Beret.

Personally, the S&W edges out the Colt on the fact that it is a DA/SA gun. Like I said, I grew up shooting them and I like not having to fiddle with a safety if I don't have too. Not that I have anything against the 1911, I'd feel completely confident with it and I do carry them off duty from time to time. But the S&W to me just had that little bit of difference enough that if I were poor and broke rookie in 1992 and could only afford one gun. I'd go with a S&W 645.

What would you choose between the two?

IMO the 645 was a pretty gun but the barrel sat way to high up and muzzle flip was only mitigated by the weight of the gun. You just couldn’t get the feel and follow up shots like you could with a tuned 1911.

Around 1986 I purchased a used 645 from a friend. It was a huge pistol and had terrible ergonomics for my hands. It shot okay but it never felt good in my hand so I sold it off. 4506 felt better in my hand but by then I discovered Sig 220 and it was my preferred SA/DA 45 ACP pistol.
I picked up a Colt 1991 at a gun show with idea of having it built as a customized carry gun. It was rough externally with cheap parts but it worked and felt like the familiar Government model in my hand. I was surprised the MSH was plastic and thought it would break but I never heard anybody having problem with them. I shot that pistol for a while and found it reliable but not very accurate but eventually sold it off as I had other quality 1911 pistols and I had lost interest in custom carry guns. That period was low point for Colt factory and 1911 pistols in general.

BTW. around 1999 I was shooting at the range and noticed a Hollywood uniform officer carrying the 4506 and a Pembroke Pines uniform officer carrying a Colt 1911 Government pistol.

A friend of mine bought a 1991A1 back in the early 90's. It doesn't suck.

Great post.


I also prefer the 1911 over the S&W's.

I've only shot the 645 of the S&W's, it was a gorgeous gun.

I bought a Para LDA that I could never get running right right, I feel like it was an important branch of the 1911 evolution path as well.

I always wanted a Para Ordnance double stack, but could never afford one. Then some years ago I bought a LLAMA double stack which was pretty much the same thing. I think people didn't like them because the magazines were no longer available and Para mags didn't work in them. I figured that for the price I would try to see if I could get Para mags to work on them, and fortunately, it just took some modification to the mag catch hole. It worked perfectly for me even with these modified mags. I even put a threaded barrel on it and ran it in some competitions. Unfortunately last year I ended up selling all my 45's as I needed the cash, and that was the last one I held on to. It's a good choice for a double stack 45 if you can't afford the Para. The only PITA is that the grips are proprietary so unless you can make your own, you pretty much have to stick with the ones it comes with.
