    PT145 Magazine Nosedive Problems

If the magazine hasn't been dropped on the feed lips...it is hard to understand why they would be changed from when you first shot it and they functioned okay. That is why I didn't address the feed lips on the mags or the extracter initially.
    I've been having the same problem with my factory PT145 mags and JHP ammo. I've used 4 or 5 different brands of FMJ with ZERO problems (around 500 FMJs shot so far).

    I initially tried Winchester JHP a month back and had multiple nosedives where the round was not coming all the way up into the chamber from the magazine.

    I then ordered Speer Gold Dot, Federal Tactical Hydra Shok, and Hornady XTP Custom (ALL JHP) and NONE of them will feed reliably out of the magazines. I received them on Aug. 4 and it's Aug 18 now, so I've been trying for 2 weeks with them.

    I have not gone to the range to shoot them, as I already know I'll be dealing with nose dives when I get there and don't want to waste the 30 minutes to/from the range to verify a problem I know I have.

    I've loaded each of the 4 brands of JHP in each magazine and with a full 10 rounds in, they will not feed properly -- either as a manual slide eject/load through the gun or manually cycling out the rounds in the magazine.

    With all FMJ rounds, I have ZERO problems with either of the two procedures above and they all feed out of the magazine perfectly.

    I've cleaned both magazines and they both previously had small notches/grooves on the feed lip that I've smoothed out. Neither have been dropped.

    I've read MULTIPLE threads on this on many forums and have tried most, if not all, of the solutions: my feed ramp is polished and smooth and the magazines are cleaned. I've tried bending the tip of the spring of one magazine up a little more and made sure the openings at the top of the magazines allow enough space for the JHP to pass through.

    I've left one magazine fully loaded with the Hornady JHP for 3 days without touching it to see if that would help in any way. I've also manually loaded and unloaded the magazines multiple times a day previously to see if that would help.

    Before I'd try to manually run the rounds through the gun, I'd make sure I was getting smooth ejection out of the magazine by hand. It seems like the spring doesn't push the rounds up high enough in the front to go over the lip of the magazine as it exits.

    The best I've gotten so far is if I load only -7- rounds in the magazine, I can get all 7 to feed out of the magazine manually -AND- through the gun with no issues. However, once I add another round into the magazine I get a nosedive. I have to rack the slide for rounds 10, 9, 8, and 7 to come into the chamber when the magazine is fully loaded. Tapping the magazine has no effect.

    Wednesday is the last day I'll try to fix the magazines before I call Taurus for their assistance.

    I have no worries if the gun will fire if I need it while loaded with FMJ, but I'd rather load it with JHP for self defense. And with JHP not working AT ALL, I just keep the FMJ loaded.

    Any suggestions or ideas other than what I've tried would be greatly appreciated.

    Re: PT145 Magazine Nosedive Problems

    Jflorida, in reading your thread, I get one possible clue, and that is you have loaded individual rounds through the ejection port. This may have caused a bow in the extracter which no longer allows the extracter to keep a firm enough hold on the rim of the cartridge. The longer fmj rounds would be affected less than the than the shorter jhp rounds. Just a possibility, nothing in concrete on my conjecture. Autos are designed to load from the magazine allowing the cartridge to slide into the groove of the extracter. I used to load into the chamber the same way (from the ejection port ) and was warned against doing so. You may need a new extracter. Since it seems you've tried everything else, that is the only suggestion I have.

    Re: PT145 Magazine Nosedive Problems

    It sounds like you need to tweek the mag lips a little. You can take a pair of needle-nosed pliers and just grab tge forward portion of the lip and bend outwards ever so slightly. Do that to both sides and then try cycling the rounds through the gun. make tiny adjustments and cycle, if it doesn't work try it again. You'll think you aren't gaining anything, but eventually you will make it work.

    Another thing to check: Make sure you have the spring turned the right way, there is a wrong way. Hold the spring vertically and look at the side, the angle of the spring should be pointing up towards the front of the magazine.

    Also, when you take it apart look inside the mag and see if there are any unfinished bumps from the being welded together. File them off if they are there.

    Don't worry about screwing them up, they don't work right anyways.

    Mine work fine, but on did get bent and I had to tweek it back into submission.

    Re: PT145 Magazine Nosedive Problems

    Seabear, since Jflorida is having the same problem with four different mags, I have less tendancy to think it is a mag problem.

    Re: PT145 Magazine Nosedive Problems

    It may not be Jake, could be a feed ramp issue but the mags are an easy place to start. He mentioned four brands of ammo, but I think he only has two mags because he said.

    "I've cleaned both magazines and they both previously had small notches/grooves on the feed lip that I've smoothed out. Neither have been dropped".

    JFlorida, it doesn't take dropping to bend the lips on the magazines. One of mine got bent when a shooting buddy of mine slammed a mad in like he was serving a volleyball. Hell, it even bent the back wall of the mag. Took quirte a bit of tweeking to make it function again. I couldn't even eject the rounds with my thumb. Stanger things have happened.

    Re: PT145 Magazine Nosedive Problems

    There is definitely something wrong with my PT145.

    1st issue is the magazines. The first 2 hollow point roundsnose dive (down and to the left side of the feed ramp) in both original magazines, they load without issue after that. It's only when releasing the slide on a HP and then the follow up shot and even then, tapping the bottom of the magazine pushes the bullet up enough to let the slide close. Both magazines have a slight gap when locked in place so I'm wondering if stiffer springs would help at this point since Taurus can't get the clearance right.

    2nd issue is the throat of the barrel. Today is the second time I've had brass get stuck in it so hard that I could not cycle the slide. Granted, it's only happened twice in about 500 rounds but that's way more than it ever should.

    It bothers me that I had ZERO problems shooting hollow points and regular FMJ for almost 400 rounds and all of a sudden these problems appeared. Guess I'll be sending my only carry gun to Taurus for a couple months

    I've tried tweaking the magazines, removing/cleaning/replacing the mag springs, both mags have the new followers and I've cleaned the whole thing several times and lubed enough.

    I wish I could say "oops, that's what I did" but I haven't. I've always loaded the magazine, inserted it into the gun and either let the slide lock go (if it was locked back) or racked one in the chamber (if the slide was closed). After loading that one, I'll add the 10th round back into the magazine and reinsert it.

    Also just to clarify, I've only got 2 magazines. The original poster in the 24/7 thread did have 4 magazines.

    I'll try tweaking the magazine again. I've cleaned and made sure the feed lip on both are smooth, but any other tweaking (adjusting the opening, bending the spring top some, etc) has been on only 1 magazine. That way if I mess it up, I still have one that works

    That's why I believe it's a magazine-related issue and not the gun itself. I can't eject the first few rounds by hand with JHP, but can with FMJ.

    When I get back home later, I'll reinspect the "non-tweaked" magazine and spring vs. the "tweaked" one to make sure the springs are inserted the same and see what else I can figure out.

    Thanks again for the insight.

    Re: PT145 Magazine Nosedive Problems

    Just a thought ...

    I wonder how many magazines have the feed lips altered and/or damaged during loading by hand? I know I have a VERY difficult time loading by hand without using the lips for leverage against the follower and spring.

    The UpLULA loader (http://www.youtube.com/watch?v=Zos_7e-c4t0) is the best thing to ever come along for loading magazines with out doing any damage to them - or to one's fingers.
