I have been shooting for years and have bought many firearms, but I have never purchased a 1911. They have always intrigued me, but I never fronted the cash to purchase one. However, last weekend, an uncle of mine gave me his 1911. It's a Colt .45 Government Mark IV Series 70. I traced the serial number, and it appears to be linked to those models that were made in 1971. I am highly interested in firing it and perhaps one day carrying it. I didn't know if anyone had tips on the weapon concerning replacing parts etc. It's in excellent condition. My uncle had installed Pachmayer (sp?) grips on the gun. It fits great in my hand. I also need some new magazines. I heard that Wilson Combat made some killer mags. True??? Any tips/suggestions would be appreciated. It sounds like many of you know what you're talking about. Thanks...

Welcome to the forum aerox711!

Your uncle gave you a very nice gift. I have one just like the one you've received. I've still got the box with it. If yours is in excellent condition, its worth 700-900.00

The only thing that you may want to do some watching over is the barrel bushing. Instead of it being a solid piece, it has been split into 4 fingers. Which if not fitted properly from the factory, can break. Generally due to insufficient clearance in the slide causing the fingers to bow inward, which puts undue stress on the skirt of the bushing (where the fingers meet the solid part of the bushing). After time this will cause the fingers to fatigue a bit then eventually break. I've seen then go for a life time and not cause any problems as well. If you're going to carry it for........say defense purposes, I would suggest replacing the bushing with a solid type.

As for other parts.........go out and enjoy it before thinking about any mods. Do some research on 1911's. You'll find some great reading on this forum, and the home page as well.

I use Wilson 47D mags. for duty use. One thing that I'm sure most folks here will chime in on.........don't get a quality gun, then give it cheap mags. Your nice gun will give you fits ever after.

Happy shooting.........

Wichaka is right to the point. Quality mags are important. Also, do yourself a favor and get rid of that barrel bushing, as soon as you can.

Then, go out a shoot the pistol. If your hand gets scratched between the index finger and the thumb, have a decent gunsmith install a beavertail for you and you are done.

Welcome to the Forums.

Welcome to the 1911 family, you have a pistol that many 1911 afficionados would want to have(including me! )

Do what Wichaka and John have advice, go out and shoot and have fun before you do any mod. with it.


'I rather have it and don't need it, than not have it when I need it'

Great! Thanks alot guys. I spoke to someone today who advised that I should atleast replace the guide spring. He suggested one rated at 18.5 lbs. I have a MIDWAYUSA catalog that sells Wilson Combat accessories...is that a good choice? Also, where can I find one of those bushings? Any links would be helpful. Does anyone suggest purchasing a full length guide rod, instead of having the shorted 2-piece? I have heard of guys doing that, but again, this is all new to me. I am an officer in NC and I would love to wear it off duty, but I NEED it to be reliable and dependable. Thanks for all of the great advise thus far. Keep it coming....

aerox711, you might want to look at replacing the spring...........afterall, sitting in the gun for the last 30years........I'm sure it has taken a 'set'

I would advise heavily against putting a 18.5lb spring in it. All 1911's if made properly will cycle with finger pressure. If you put a heavier spring in it, the forward motion of the slide going back into battery while cycling will jar the gun more. Which means its slamming itself more than it should, and its harder to keep it on target for followup shots. Most springs coming out in factory guns these days, don't measure up to the lbs. they're rated for. Example, the ones I've tested for the gun you have (which is supposed to be a 16lb spring) usually rate out anywhere from the upper 14's to mid 15lbs. Commanders are to have 18lb springs, but rate out in the 16-17lb area.

If you're going to replace the spring, go with a 16lb Wolff. Wolff seems to make their springs closest to their advertised rating. I've got one here for ya that I'll send to you. Just give me a PM with your address.

As for aftermarket parts, I would suggest you look at Brownell's. They have their own web site brownells.com, and you can order a catalog. They have everything you need..........or don't need.

Guiderods.........uh...........well, you're going to get differing opinions here.
I use 2 piece full length guide rods on all my 1911's. There's no advantage to using them as maybe you may have read. I just like the spring to ride on something.......and not snaking around inside the gun. I've heard of the 2 piece styles coming loose during firing. I've not had that problem. If they're tightened up properly, they'll stay together. However, should you have a problem with one coming apart..........dab a bit of blue loc-tite on the threads. It will only come apart when you want it.........not when it decides.

The only other thing that may need attention...........is what John mentioned..........that's the grip safety. After an extended shooting session, that safety will dig into the web of your hand........and eventually blood will flow. If you're not wanting to alter the frame, Wilson makes a drop in type safety that requires no grinding on the frame. And they fit pretty well and look good too.

If you need reliability done on the gun, you can send it me. I build 1911's for L.E. personel.

There are people on here with alot of experience and knowledge. Don't be affraid to ask any questions. You may want to use the 'search' function to look for past forum threads on some of the questions you may have.

Again welcome aboard and have fun with your 1911.

I'll have to differentiate my position, as far as the guide rods are concerned, with reference to Wichaka's view above.

I agree that they offer no advantage, actually they make your life more difficult, by making the disassembly more complicated. I disagree on the fact that the spring is shaking around inside the gun, if you do not use a full-length guide rod (FLGR). There is no much room in there, to let the spring move around.

I used to have FLGR in both my pistols for years, actually when my good friend Alan Tillman customized my 9mm Springfield, it was one of the first items on the list. After years of using them, I got rid of them and went back to the original setup. As expected, no difference, and now I can strip the thing without using any bloody allen key.

Of course, this is only my 2 Eurocents.

I agree that the term 'snaking' is really not accurate. True there is not much room between the frame and barrel for much movement, but there is some. I just like the spring to coil in a straight(er) line.

Again aerox711, its going to be a personl pref.

So John whats the exchange rate for the Eurocents?
Are you in the hole, or do I need to send you the diff.?

Thanks guys. I spoke to a guy that works at my department today, and he basically said word for word what you said, Wichaka. I was just on the Brownells site a moment ago, and there's plenty of options to choose from. I'm looking at a new hammer/trigger as well. It all depends. I'm sure the girlfriend will have my head when she realizes just how much money I'm about to put into this weapon. I'm excited about it though. I WAS told however today, to go towards a 18.5-20.0 lb. spring system. If I can afford then, I'll try the 16 and the 18.5, and just see what works. Wilson Combat seems to have alot of the parts that I need. I'm pumped about it all!

You've gotten alot of good advice about your colt so far, the best I can give you is to put in a new wolf or wilson combat recoil spring, get a couple hundred rounds of ammo and head to the range. If you know anyone with a 1911 set up differently (long trigger, full length guide rod, better sights, whatever,) see if they might let you shoot it, that might give you an idea which direction you want to go. It sounds like you are already hooked so look at it this way, since the gun was a gift, even if you spend a few hundred bucks on it you're still in good shape. I've got a series 70 MK IV myself that I recently paid $600 for and was happy with the price. Have fun with your new gun. Also I've had very good results with wilson combat and chip mccormick magazines.
