    The item was exactly as described brand new in box and unfortunately i was unable to keep it due to financial issues and will have to sell the firearm associated, Nimrod has and always will have high quality items for sale. He accepted my return and it took a little longer than usual but once I contacted requesting the refund it was promptly issued. He has the best prices and highest quality items for those prices. Will continue to be a customer always! Everything else worked flawlessly from him

    My Glock 17 magazine springs arrived today. They're the standard 10 coil for the 17 round magazine. They arrived well packaged and in perfect shape. Seller stated that these springs are Glock OEM. They look as described by the seller. They look good. Color is correct. They came in a clear package. Good price as well. Can't speak for quality until I give them a workout. They are installed though. So far I'm happy. I will purchase from this seller again.

    The package arrived 2 days early based on the tracking on eBay sight. Seller also requested a signature for delivery which I really appreciated. It was a small order of relatively low value but they insisted that it arrive to me with verification. I have done business with these people a number of times in the past and they have always been great. Bid and buy with confidence from this seller. Thank you .

    A bit of Promag awesomeness!

    I was using my S&W M&P Shield at the range some weeks ago and my aim seemed to be off. The more I tried to stabilize my weapon as I shot at the targets, the more off target my shots became. Then I realized that the recoil was causing my hand to slip at the bottom of the grip. Of course I never have this problem with my full size M&P. Additionally, I only shoot .40 cal and there's no way I would switch to 9mm just to reduce some recoil. I spent many weeks doing lots of research. I saw many brands out there that offer magazine extensions with modifications to the original. I dont have time for all that and many were too expensive. I was about to give up and then I saw it. Not only did Promag offer an extended magazine for the Shield, it needed no modifications and it looked great. Bought ...

    Strong feed spring

    The mag functions well enough. It fits in the weapon easily. It operates the slide lock when the magazine is empty, as it should. The empty magazine slides out smoothly when the mag release button is pushed. My only drawback with this magazine is the extra stiff feed spring makes it very difficult to load it up fully. Initially, I could only load four rounds the first try. So, I took a wood carpenters pencil and worked the carrier up and down multiple times to break it in. After that, I had a hard time putting 8 rounds in it. My next step will be to disassemble it and smooth any friction surfaces inside of it. If that doesn't work out, I'll try modifying the spring to get the full 9 round count inside of it. I'm not going any further on my recommendations or assessment of it ...

    Well it sounded like a good idea...

    REAAAALLY extends the grip which isn't horrible at the range, but the sleeve has a gap (on the two that i got). They will NOT feed flat nosed target rounds (Federal and Aguilla) and had feed problems with round nose ammo as well (FORGET HOLLOW POINTS). I have filed down and rounded off where the mag well meets the feed ramp in hopes this fixes it. My stock 6 and 7 round mags worked perfectly. The quality of materials is very good, just operates like a 'Second' mag.

    Good idea poorly executed

    Bought two, one works fine, the other does not. They load comparable to any other mag and I need a loader. The spring is too tight on one of them and the Maglula loader finger gets stuck between rounds. Also one of them can only load 7 because if I put in 9, the first two rounds hang up on the lip. I will have to file it down a bit if the spring doesn’t relax. The grip extensions are too rough and should be smoothed out. A better design would be to match them with the handgun grip. Also, the grip extensions move up and down the mag. Overall, the quality is just not that good.

    Improves the capacity of my Shield

    I only fired two magazines through this as of yet, a pretty small test. The three star rating was because I experienced a failure to feed on the second round of the first mag full. Not uncommon with a new mag, as is the heavy spring pressure. I suspect the two are related and also suspect a little use will solve both glitches. In northern Minn with two foot of snow, so I'm not going to loose a bunch of brass testing this any more for now. This will need to prove itself before I will trust it with my life. But it's a good usable range mag at least, and may prove dependable. I'll be ordering another.
