Been thinking about getting a Colt 1911 for the 5-inch barrel and .45 ACP ammo, for the express purpose of getting a backup weapon for hunting. How did the 1911 pistol get the nickname, Jam-o-Matic (at 56 sec in the video below)?



During live fire training at KHSC, I experienced a misfire in an unidentified .45 pistol. I wish I wrote down the name of weapon for future reference.

....
The 1911 pistols earned the jamamatic name when competitive target shooters tried feeding the pistols with wadcutting-type ammunition.
As the name implies, the bullet cuts out a wad of paper like an office hole puncher. That target-style of ammo is usually loaded at reduced velocities to make it gentler on the gun and the shooter.it also helps recovery for succeeding shots especially during rapid-fire competition.

The problem is that the original 1911 pattern was designed for combat use with full power ball (round nose) ammunition.
Thus, it took a significant modifications to make it reliable with low-powered target ammo.
Compounding the problem was that the barrels were usually replaced with match-grade barrels which have tighter tolerances.
Compounding that problem was that the slide to frame fit would typically be tightened to reduce accuracy-robbing variations.
Compounding the problem was that the magazines were designed to function with military ball ammo, not with wadcutter ammo.
Compounding that problem was that the traditional wadcutter ammo for 45acp was a short stubby thing as compared to ball.
That change in ammo length screws up the entire geometry of the feeding system.

But fear not, modern manufacturing methods have made the 1911 platform much more reliable.

Why would you buy HK mags? You own mags?

#notrealdoctors are very generous.  They are willing to buy HK mags for "a friend" who has say VP9s.   

So a FYI, I called Colt's custom shop seeing if they can basically make a M45A1.  And they said no. Their custom shop is to modify existing Colts.  So there's like 4 pages of prices, descriptions at what they can do.  But you need the existing Colt 1911 to start the process.  So send in your Colt 1911 and they do what you need.

there's this option - Make your own!

not bad for the price. A week of hands on building your own 1911. Most major tools are provided. A set of Mitutoyos are about $120

I got a Colt Gold Cup.  I like shooting it.  Thing is probably more accurate than I am.

A short but true story.....

I go the park by my house to walk the dog and practice his tricks.
There is an elementary school next to the park.
The kids sometimes watch me practicing the doggy tricks.
So one day I'm just walking around with dog and a little girl yells out....

JUST DO SOMETHING  ALREADY!

Hypothetically. . .

Maybe if the gun shots low and left. . .

What made you decide to go with a Colt M45A1?  Because of recent adoption? 

I considered a Colt competition a while back.  Those had a good, or at least decent reputation.  I think they were a little overpriced for the pony, but I think good gun. 

When you get yours, we can have a 2a 1911 day and everyone can challenge you and your new spiffy 1911.

#1 was cause of holster selection. The SIG Scorpion has a squarish slide.  So although I did contact a guy who has a Safari holster for it, I've read on other forums that said holster doesn't fit.  With the M45, I know for sure Safari makes a holster and it will fit.  The shitty part is that I am spending like $600 more on the Colt.  But I could spend just as much and headache trying to fit a holster.  The other route is custom Kydex, which is easy to find, but no foreskin.  I like the foreskin.  See pic below.

Then #2 most recent (due to checking out mags)  was a vid of the 10rd Wilson mags not ejecting from the Scorpion due to the textured grip. The front of the pistol digs into the plastic of the mag.  CM mags seem to work.  So not too big of an issue.

You basically have to strip the mag out with you hand, or dremel the 1911 or file the mag contact area.  This was 1 guy on YT.  I haven't seen others run the xtendo clips with this gun.  The grip on the Colt is smooth, this is the area on the inside of your fingers (under trigger guard).

I can appreciate looking at support gear for a handgun.  That, or lack thereof has made me not buy some pistols along the way.  Even when I was in the "try everything" phase of firearms.  That said, seems like you're really gearing up for about the same use/purpose as your current handguns (classes, training, etc).  That the Scorpion didn't work well with Wilson mags is disturbing, and hopefully not a common thing. 

For me, my 1911s are primarily for plinking as well as just having them.  I thought about competing with one in single stack, but that urge went away a long time ago.

Since this is my thread, I'll add this:

If the 1911 was over a year wait, then I was gonna get my first RDS and Gucci type Glock.  I was gonna go with the WarPoet M920 (Shadow Systems) that you can order with a Holosun RDS. Bascially a G19 platform.  Instead of RDSing the VP9 and buying a 6th holster.

He had a class (or used to have classes) where you build your own 1911.

Can you guys see if a 1911 mag fits enough into a double stack mag holder?  Or wont fit at all (like putting a circle peg into a square hole) .  Esstac to be exact if you got it.  Cause I would have to order mag holders too if they don't fit well enough.  I say well enough because my G-Code mag holders for AR mags, also can fit 2 VP9, double stack mags well enough.  They don't move around when running or fall out when running/jumping, but IDK about hanging upside down.  So when taking a pistol skill builder, I bring 6 VP9 mags and put the extra in my rifle mag holders which is on my plate carrier.

It does, and I've done it.  But not sure how secure it is.  I just have done it to get to the line and casually shoot.  Not in a class.  I can check more and let you know.

Cause depending if it fits or not is what my warbelt set up will be for HD.  That's another good thing about the Safariland holsters. They can fit the G-Code RTI hanger, so I can quick detach/attach the holster. No drilling needed.

But then again, it is easier to get a VP9 than a M45.  So in theory if the VP9 gets confiscated, then no biggie.And it's a way cheaper gun.

yes, yes.  I get why you're asking. . .

I am the only one who shot it so, no comparison data.
