Fixin to shoot this afternoon:
A 1911 with Norma .45 ACP JHPs. 50 rounds out of 7 mags.
A S&W SD9 VE, two mags of 15 each (I just can't fit 16 in these, though there is a witness hole labeled 16). This consists of JHP from Cavalry Ammunition,
National Police Ammunition, and Speer Gold Dot.
RANGE REPORT
.45 ACP Charles Daly Field 1911
I had the 8-round magazine that came with the gun, and six 7-round magazines, an Ed Bailey and five of a low-priced no-brand off ebay. The Norma JHP, for all 7 magazines, failed to chamber the initial round. I had to monkey with them until they chambered. Seems they were nose-diving. After the first round was chambered they cycled flawlessly except a failure to eject the second from the last case on the Ed Brown (there was a fresh live round in the chamber and a spent case jamming the slide). I decided to proceed with some FMJ Armscor ammo with the 1911 because it is so much fun to shoot. Again I ran all seven magazines with a box of 50 rounds (7x6+8). Here the gun performed flawlessly for all seven magazines.
The NORMA JHP are short (about 1.16") so maybe that is part of the problem, but I experienced the same thing in the past with longer JHP rounds.
One of the best things about the 1911 is that this time I did not get a grip safety spur bash mark on my hand. I think the finger grove grip insert fattening the grip slightly and forcing my hand a tad lower on the grip, as well as my filing off the sharp edges and the downward part of the spur is what made the difference.
The 9mm S&P SD9 VE was a different story.
I only ran`two magazines of 15 rounds each, but fell short of using all the ammo. Here are the results:
Speer Gold Dot: 9 rounds ran flawless
Cavalry: 7 rounds and one jam
National Police Ammunition: 8 rounds and 4 cases stuck in the chamber. I had to pry three of them out with my keys and the salesman got a rod to remove the 4th one. My range bag now has a wooden dowel in case this happens again. So I was left with 6 unshot rounds of the National Police. I thought the extractor might have broken but it looked okay and after clearing that last case, I fired the 9 Speer Gold Dots and, as I said, they ran flawlessly, so I know it is the National Police ammo not the gun. So I have a little over 2 boxes of that ammo to figure out what to do with. I think it is either a bad batch or my gun does not like this ammo.
EDIT: in the interest of fairness, National Police Ammo will give me a full refund, does not know why my gun would not shoot their ammo, and said it shoots fine out of an M&P.
