Took the new sig 1911 tacops 45acp for it's maiden voyage at the range today. Worked well, had a couple of issues with the magazines. I also got 3 new wilson combat mags i brought along also for a comparison. These are all 8 round. 4 sig and 3 Wilson combat. I would load 8 rounds in the mag, which was very difficult to get the last round in. My big problem was when it had 8 rounds it wouldn't always chamber the round. Tried slide stop and sling shot method and it would half pipe. I would take one round out of the mag (7) and it would chamber ok. When 8 were in it seemed the round was sitting too flat not tipped up to enter the chamber correctly. The issue happened witb the factory mags as well as the Wilson mags. There was a point where i was trying to tip the round up with my finger to a point where it was sitting at the correct angle. If i did that it would chamber better. Is this what you have to do? I've never had to do that in the past on anything.

Truth be told im a revolver guy so the auto pistols are not my specialty (yet). I have some experience but am i missing something. Is there a break in period on this equipment?

The gun ran perfectly after the first round chambered. The only other issue i had was in 250 rounds the slide failed to stay back on 2 occasions when the mag was empty.

Some advice and or opinions would be greatly appreciated

Thanks fellas
Corey

As you used mags from 2 different manufacturers I wonder if it's a gun issue rather than a mag problem
It would be interesting if you could borrow other types of mags and see if it happens with them as well. I wonder if the extra tension on the mag with 8 rds in it results in too much resistance when the slide is trying to push that 1st round up the feed ramp (not going fast enough)

I recall having similar 1st round feeding issues with a Browning Hi Power chambered in .40 S&W. In that case polishing the feed ramp was the solution.
 
I just bought a sig 1911 nickel 45 and just waiting for it to be transferred. But on the 9mm sig I own the mags when new were almost impossible to load 10 in. I left them fully loaded for a month and they finally settled. I think the spring was in need of some break in. I’m guessing maybe that’s your problem. If the gun works fine with 7 rounds loaded then just work that mag spring in a bit.

Im leaning toward this also. I just loaded a wilson and a sig mag, if i didn't know better i swear the ammo went in a bit easier. I took a single round and loaded it in a mag then compared it to a full mag, the single roumd sits at a good angle where the full mag, the round sits flatter, its better but not the same. Im going to load them all full and leave them till i go to the range again. Maybe that will loosen things up.

Have the mag fully loaded and sit for a week or ao before ahooting it. I do this to all mags and i never experienced any problems with them.

Also the sig are built a little better and when they are new , they tend to not run properly for the first few mags
 
My colt M45A1 was having the same feeding problems you described when I first bought it. I was actually disappointed, but I called Colt and they told me to buy a whack load of ammo and shoot it all and if it wasn’t working after 300 rounds they would refund me. After about 200-250 rounds it has not had a hiccup in almost 1500 rounds. I know it sounds like I’m just another one of those guys but it could be break in period. I certainly never believed in it myself until I had to do it with this pistol.
 
Ok, ill just keep shooting it (if i have to) :) . Been thinking its probably just a magazine issue and not a gun issue because it never fails to return to battery when shooting, it just won't pipe the first round of a full mag once in awhile. I'll run a bunch more ammo through and see what happens.

Thanks

HI; People trash talk PARAs out of the box. They do not read or follow the requested 500 round break-in request. My PARA worked fine after the 450 rounds were shot.
 
Bit of an update, I've been researching the heck out of this issue and found that what I'm experiencing is known as "nosediving". It seems most people consider this a magazine issue and there is even "anti nosedive" magazines. It seems it kinda hit and miss if you have this issue, very strong mag springs seem to cause it. I got my hands on some act mags also so i have 3 different brands now. Most people deal with it by just dropping one round out and running 7. I have my mags loaded up now trying to soften the springs then a trip to the range to see what happens.

I think this should help a lot. BTW, I have a couple nickle plated Remington 1911 mags; they were $28.00 and are they ever slick operating!
 
I watched a video on 1911 magazine issues and you can also have problems if the rounds point too high. This was apparently why the checkmate mags that come with the Sigs use the hybrid feed lips.
In my new 1911 mags the rounds are quite flat when fully loaded and as they get down to the last three rounds or so the rounds begin to point up more. I think this is the design. Under high spring tensions the rounds are flat and pop up quick. Under less tension they angle upwards slightly.
I can’t wait to try mine out soon. Waiting on the paperwork. If the checkmate mags give issues I’ll buy mec gar ones and try them.
 
Update on the feeding issue. I had all my mags loaded for 2 weeks. Hit the range today, sent 250 rounds of 230 grain hollow points down range with no ftf's. No issues at all for that matter. The sig worked like a champ. Very happy. Used all my mags, factory checkmate, wilson, and the act mags. All worked perfectly, the springs were noticeably lighter from being loaded up. I will perform that break in on all future mags. It was absolutely the issue.

Awesome, glad that worked out for you! I need to remember to charge my mags tonight and see if that helps my issues.

Cheers
 
Basically, with 1911 mags you want to stay away from this:

The first mags look like checkmate that came with my sig, they now work with loading them. The second look like Wilson mags,have 3 of those also. They had the same nose diving issue until I loaded them for 2 weeks also. Same with the act mags. The act mags did work the best for me. I will probably get.more of them.

Yes those second image mags are the Wilsons. They prevent nosedives because the follower is far more sturdy than the metal strands of the cheap mags up to. But you don't have to buy Wilsons, there's many options for those kinds of mags out there.
